What machine has the best return on investment. I've been learning a lot about machining the past year. If I bought an old lathe for $5k with tooling and maybe a bridgeport would I be able to make money? Would the only available work be repairs? I like manual stuff a lot more than automated, but I guess I'm just wondering if there is any money in it. I'm reasonably competent with diy stuff so I'm not worried about figuring it out.

Maybe? If you're doing general job shop work, it's going to be rough, if you find a niche, you can make money.
>>
What is the cost of this huge turbo and how do I install it on my 2003 fiat Panda is the real question here
>>
>>2222644
You wont make any money doing manual machining with stuff like that. The only places you make money in manual machining is in really big stuff (IE large shafts used in industrial purposes) or doing high precision one off or low run prototyping, the latter requiring a lot of experience.

CNC is what you need to be proficient in for employment these days for most machining.

Pirate it. I pirated SW and Inventor.

If you can't pirate it get Fusion 360 for practicing, it comes with a free CAM add on too.

I am currently working on a radial engine in Fusion.

What differentiates Inventor from SW?
I'm learning Fusion 360 right now and think it's pretty cool, but I read a lot of people talk about how it's retarded compared to SW.
And the makerspace I just joined only has SW for their CNC machines area so I wanted to start using SW.
>>
>>2223537
Fusion is cloud based and is useful for group projects where several people work on something. But overall it is inferior to Inventor since Inventor has built in features for generating various mechanical elements such as spur gears, worm gears,etc and Fusion relies on the community for creating these plug ins. People generally say that Autodesk products are more intuitive than SW, but it all depends from person to person.

In SW for example you can rotate your model by clicking the scroll button while in Fusion you have to click the scroll button + shift, which is rather annoying. There are probably hundreds of these little details which make the workflow better in one program and worse in the other. I personally like the look and feeling of SW much more than those of Inventor and Fusion.

how bad is this for a brand new lathe?
it doesn't look like normal rust from water, it looks like some kind of corrosive was spilled on it.
Most is on the chuck and ways under the chuck, but there is also some small pitting on the ways where the saddle will travel.

They are cool as hell for what you get for the money
but you are going to spending $12k+ for one spec-ed to a point where its nice to use
>>
>>2223774
im thinking about that, definitely want the tool changer and such. Mostly wondering if theres any unexpected hurdles I would run into getting this into a home garage setup. I'm expecting to need an electrician to get me 3 phase power and more juice from my circuit, and pay to have tormach setup and test it. But other than that am i going to need any paid subscription software or can I use open source freeware with it.
>>
>>2223782
Tormachs run off 110v single phase
If you want to use 3 phase machines you can just use a VFD off your single phase 110v
>>
>>2222866
probably like $10,000 or so, depends on how nice you want the surface finish and how close to the cad model and the inspection process

material too but since it's likely jet engine related it's probably titanium or inconel or stainless
>>
>>2223710
yeah just clean it off, it won't matter.

unless it's actually pitted to fuck on the ways or something

get all the abrasives out from between the sliding surfaces before use though! rust is abrasive.
>>
>>2223710
Spray with corrosion preventive or heavy oil after cleaning and be sure to operate in a dry room with a dehumidifier if necessary. Flash rust sux.
>>
>>2223818
i think that's too big to be an APU and it's definitely not part of a conventional jet engine. probably stainless for a pump of some sort.
>>
>>2223858
oh yeah my mistake, jet engines don't use radial compressors like that they use axial ones

>money from old lathe

Yes, it's really. You always have a customers who want Waste discs or cut threads.

If you want more money, You have to sharpen the foundation bolts.

It is not a problem to recoup one lathe.

Sorry for my English.

Thanks Russianon. I’ve seen some good machinists on YouTube from Russia using inexpensive equipment. A lot of talent in your country.

What do you mean by “waste discs” and what is a “foundation bolt”?

As I said I have a soft voice and can't project my voice well because I'm a tiny twinklet and my shyness means I always felt too awkward to just rocket 5 meters to the nearest person and strike up random convo anyway.

I don't even care about losing the job as much as I care about the "not fitting in" aspect. It feels like all the effort I have previously put into building my self confidence and ability to fit into workplace banter has been brutally shattered.

Anon, thats a throwaway line they use to try and make it seem like you are the problem instead of their lack of ability to keep work rolling. Tactic to keep you from seeking unemployment.
Every shop has assholes that everyone dosdnt like, quiet guys who just dont give a single shit about you or anyone else. And as long as they keep shit rolling, they keep their job.

Its not a social group, its a machine shop.
Nepotism does play its part for all the big brown nosers. But in this case its literally just a failing on the company itself.
They are going to wait 6-8 months (maybe more) before finding another warm body. Until then everyone will just take on your workload.
They are just pushing their luck trying to play the numbers game during this downturn.

Last year I had an internship in a machining shop as CAD-et for 3 months.

I have social anxiety and when I would show up every day I wouldn't say "good morning" to the workers because I didn't want to make a fool of myself (it tends to be loud as you said, so your greeting is not heard anyways) and just went straight to the office. My mentor said to me that people noticed it and were complaining about it. One time one of the engineers came into the office and asked out loudly "Why doesn't he talk?" and the mentor replied "What can you do, it's just the way he is", which I understood as "He is a socially inept sperg".

Some coworkers would ask random question like "When will you get married", more as joke, I assume and I just said "when I save some money" even tho I never held hands with a female. The workers there were your typical small town, family oriented types of people who tend to be more relaxed/chatty and me being a city dweller who just wanted to mind his own business didn't help at all.

In the end I wasn't offered a long term position and I am certain that my personality was one of the reasons.

>hey john. how's it going?
>did you ever do [X] that you said you were going to do? how'd that go?
You don't even have to give one flying fuck about John, his stupid life, how he is, or how [X] went. Just forget about it all as soon as you're done playing nice.

Its really not hard to be a man of few words, you have to be tactful about it.
When people say good morning, just give a simple "hey" and nod your head.
KHV isnt that hard to lie about either, just say you recently got out of a really shitty relationship and cant deal with bitches right now.
That gets you a ton of leeway, when it comes up again in a year, say youve been going on a few dates and they were fucking awful.
It just stops being a thing you talk about after a while.

Small talk is easy, building a work persona is easy.
The problem is you have to be diligent from the beginning, if not you get blackballed. You fucked up from the beginning.

Youll realize people at work dont ACTUALLY give a fuck about your life, your girlfriend, your hobbies and ambitions. They are just bored as fuck at work and want to talk about nonsense to pass the time.

Do not download the 2022 patcher, the license server emulator is already included with the torrent.

im kinda the same way
peter stanton made a couple videos about this and how his autism/aspergers would always make people perceive him as a giant asshole because he couldn't converse like other people in the shop
not being socially confident somehow triggers this instinctual aggression in other people, even people that aren't assholes outright, its like its hardwired in to take advantage of people with poor social skills
im still abysmal at socializing but I can manage to greet people and express some interest in their space, most people are attention whores and will greatly appreciate you asking the most mundane questions if it revolves around them.
best piece of advice i ever heard was that if you are the initiator in a social situation/engagement you have an immediate upper hand and it makes things a million times easier
IE never wait for the other person to say hello, always be the first and never hesitate, the longer you hesitate the more difficult is becomes
you can become a complete sperg and just really aggressively greet people and take them off guard and unsettle them this way, creeping people out in this regard is a million times better because they can feel a bit threatened by you instead of the other way around
its better to be super obnoxious to the point where you are fucking up other peoples owrk than quiet and introverted and being productive
normal people are faggots
i don't know why they act like this but they do

The true answer is it depends. There’s two paths i saw, one was to open your own job shop making things for other ppl. The other is to come up with some product or component you can make yourself and then sell as a product.

The second involves a lot more than machining but if you make parts for other people you can earn a reputation for making good stuff. Theres fewer machinists now than ever so demand is up.

oh it's already more expensive, the $4,000 I spent was on the machine and it's optional upgrades as well as the cast iron base and some accessories like a vise, and of course shipping. thank God no tax though. I checked back the other day for shits and giggles and just the mill itself in that configuration is now $4,000 on its own. it's nearly $1,000 more expensive to buy exactly what I did right now.

Just buy the 5019 from the beginning.
Unless you have the means, and want, to build the conversion parts on a different milling machine, you will be stuck buying them made by someone else
That will add up quicker than you think.

I'm white and australian, they're a reference surface. before the Y axis slides get scraped I scrape the Y ref surface so I can check alignment while I match the back of the knee to the column. there's no need to scrape the Z ref surface but you can tweak it with little care for depth of scrape and then use it to map out the flat ways. that Z axis ref surface was scraped with a custom granite spotting plate, precision level and planekator to check for twist and convexity. I wouldnt do this on a customers mill but this is a personal mill so i dont really care about the hours

This is the most ugly scrapped surface i've ever seen. No wonder you guys can't build your own submarines.

>>2228185
I think the scrape marks are just longer than most pro scraping, or something.

I would use a machine scraped like that, no prob.
>>
>>2228185
That was about 4 cycles in, I think this was the print at about 8 passes in. cradle was fairly low to the ground so very awkward to scrape. finished PPI was about 32ppi on the exposed ways and 40PPI on the rear of the knee before it was flaked
>>
>>2228187
This is a bit of Biax power scraping with a 60mm radius blade and about a 3/16" length if stroke. I usually finish scrape with the biax and its considerably faster but I am trying to get more confident in the moore style.

no I didn't get the dro version, it was on back order as well and plus it was like $600 for a $300 worth of dro I couldn't bring myself to do it. the only reason I got the pdf version over the basic like I was originally (other than the basic being back ordered as well) is that it's cheaper to get the PDF then to get the head and x-motor later and you can't add the quill feed later, at least not easily and definitely not cheaply. I believe you can CNC this model but the 940 is the more popular one for that especially because you can get it with hardened ways.

Interviewed at a place a few years back that did most of their toolroom work on an old VF-5 (I think at least), thing had the monochrome orange phosphor CRT display. Half the stuff on the production floor had "Y2K ready" decals slapped on them. The guys said it did everything they needed it to do. Ended up taking a job in a shop that wasn't stuck in the late 90s and instead in the mid 00s though.

spent the last few hours after I came home slapping her together and cleaning the cosmoline and metal dust/shavings off and got about half way done. I haven't taken a cut yet but I think so far the only thing I don't like is they changed the head motor switch from an on-off-on to 2 separate momentary buttons. I liked in the video reviews of the older revisions you could just flick it and it would automatically run to the limit switches if you desired instead of having to hold it for the like 2 minutes it takes to go all the way up or down. I think I might replace the buttons with latching ones or something. also I'll have to raise it up by like a foot because the table is right at dick level and I don't feel like hunching over to use this thing the entire time.
I have to say, I know it's a Chinese machine tool so presentation is optional but God damn some of the casting/paint of the smaller parts is horrible and it's already shedding it's cheap white paint and bondo like dandruff. I knew this was going to happen eventually but I thought for 4000 dollars it would at least make it to the first cut before it would get like this. also there are some rust and casting issues I'll be contacting pm about that I'll post here.

and I can't tell if this is rust or a poor paint job or bondo or what on the fine feed. there's a couple other shitty casting artifacts or poor finish on other controls like the drill press handle but I didn't bother with pictures.
oh and 2 more things I remember I didn't like, 1 the main power cable was only like 14 gauge I think, I would have hoped for at least 12 or 10 gauge with a 1.5 hp motor and power feed, and 2 the cable that goes from the box on be back to the switch panel is too short when you try to tilt the head if it's too low you won't have enough slack. I'm not sure when this would ever be a problem if ever but still an oversight that could have been fixed with an extra 2 inches of cable.

Yeah, it was strange feeling, especially on the Z where it would be easy to dent the part.
I looked up this mill and it was surprising to me that they are still made, I think one costs around $25k.

Isn't something like this super obsolete? Where would a machine like this be used to still make it sellable?
>>
>>2228847
Yikes. Thats pretty bad. Is that on the machine or base?

Your situation looks similar to mine with the lathe I bought from them.
They are supposed to inspect these things before shipping but they obviously aren't doing that.

I thought it was pretty lame to offer only 300 bucks back on the lathe I bought because of all that rust, the shipping they are paying to have that one returned and the new one sent is probably costing them over 300 bucks.

that's the base. yeah clearly, I would say they're just giving it a 5-minute once over to make sure there's no exceedingly obvious damage, but that obviously that isn't the case since all these issues on yours and my machine are so apparent even in a 3 second glance even fuckin Ray Charles can see it. I have a feeling they're going to offer me the same thing, maybe a replacement y screw or something too. well I'm sure their margins more than plenty allow for exchanges, just like how shoplifting losses are rolled into prices at the store. I don't think they're hurting too bad over a few hundred bucks for one or two guys.

Fusion 360 is infuriating.
Do one thing, have to do it again, EXACT same procedure, and it won't let you. No constraints, should be simple, nope. Constraints themselves are so tiny and obscure you constantly have to zoom in crazy amounts if you are working a piece thats like 20 inches large. Selecting features is annoying as fuck and always picks something that is farther away from your cursor than the feature you want. Things disappearing, unable to see things in the past history timeline. Lofting makes me want to punch my computer. Constantly crashes. You need a super computer to run it if you are doing any sort of tool paths that aren't ridiculously simple.
This program sucks shit.

>>2230264
Another thing to consider is the lower limit of your spindle speed. I did some work on HY-80 using a 1" endmill on a knee mill recently. Didn't have any real issues, but I was nearly bottomed out on the back gear to get nice chips. The motor sounded a little strained, but not horribly so. .015"-.020" width of cut, 2" depth, .005 theoretical chip load. I think I was using 50 SFM for spindle speed.
Would probably be fine for aluminum and soft steels though.

I bet you're a blast at parties.

I would do it just for fun and so I can take stupid pictures, not because I actually have a need to evaporate material 1.5x5 inches at a time.

Quantity? If it's one or two parts, what I usually do is take two drills of the same diameter. Grind one flat, leave one alone. Drill your pilot hole with the chisel point, follow with the flat faced drill to flatten the hole. If it's a 20,000 part order obviously purchase a carbide flat bottom drill.

Oh look, a retard who has never bothered to read the FTC website for specifics on country of origin label laws, and has completely made shit up in his head.
Even worse, he doesnt realize Obama cracked down on it and made the FTC labeling law much stricter than the original 1997 law was.

There is a reason that "of global materials", "assembled","processed", and "built" in the USA came out of nowhere about 10 years ago.
The wordage was cracked down on.

To be labeled "made in the USA", the raw materials have to be "virtually all" domestic, and the "substantial transformation" of those materials must be in the USA.
They make the distinction based upon the final total value of the said materials.

>The steel used to make a single component of a complex product (for example, the steel used in the case of a computer’s floppy drive) is an early input into the computer’s manufacture, and is likely to constitute a very small portion of the final product’s total cost. On the other hand, the steel in a product like a pipe or a wrench is a direct and significant input. Whether the steel in a pipe or wrench is imported would be a significant factor in evaluating whether the finished product is "all or virtually all" made in the U.S.

>A company manufactures food processors in its U.S. plant, making most of the parts, including the housing and blade, from U.S. materials. The motor, which constitutes 50 percent of the food processor’s total manufacturing costs, is bought from a U.S. supplier. The food processor manufacturer knows that the motor is assembled in a U.S. factory. Even though most of the parts of the food processor are of U.S. origin, the final assembly is in the U.S., and the motor is assembled in the U.S., the food processor is not considered "all or virtually all" American-made if the motor itself is made of imported parts that constitute a significant percentage of the appliance’s total manufacturing cost.

So in the case of the Cle-Line drill bits saying Made in the USA of Global materials, thats a "qualified" made in the USA claim.
The "transformative work" legally must be done in the USA, so all the bits were ground in the USA, and they may or may not have forced the index to be "transformed" in the USA too depending on whether it was considered a substantial part of the final products value.

So the steel is from china, which makes sense seeing how the anon posted the company does
>"from mining the ore, to making the steel, to fabricating finished goods. "

Where retards get this idea that
>" the bits, index and box were all MADE in China, shipped over, and then everything was put together and packaged here by minimum wage Factory workers "
can be a qualified USA claim is beyond me.

When Dewalt says "built in the USA of US and Global Materials", there is still USA made parts in it, just not "transformed" in the factory.
When a brand goes and just says "built" without a claim of any US materials, then sure you can say its all chinese stuff, because it is.

But hey, good on you for hating on the last remaining factories.
How do you expect factory work and independence to ever come back if you are going to kill off even the basic assembling jobs.
Is that how you get momentum going?

Huh, based

I am now more confident in the quality of that index I posted about buying. I wonder if you could find a US-made drill set made from actual US steel, if such a thing still exists.
I was okay with it even after buying because it was advertised as Cleveland, not Cle-Line, and Greenfield Industries which owns those brands (and is owned by TDC) as well as Chicago-Latrobe says that "Cleveland" is their industrial/production tier brand, "Cle-Line" is more home/hobby/repair oriented. Chicago-Latrobe is somewhere inbetween

I might get one of those red box Cleveland sets as well, since they say "Cle-Forge" and that seems like a pre-2009 trademark of Cleveland's.

I have an idea for a tailstock mounted chuck, it's something I could really use when mounting pipes or something long that I can't center drill in the lathe
I'd buy one of those small chinese chucks, 80 or 100mm and machine a backplate with axial and radial bearings to be mounted on an MT3 arbor that would fit my tailstock

vacuuming up a pound of chips spread across the floor in a 6 foot radius from my mill is getting old. I'm thinking of encasing it in a curtain (clear PVC like 1mm thick) on 3 sides and a small magnetic chip shield in the front to keep them contained. has anyone done something similar? i was going to attach the curtain frame to the rim of the stand unlike pic rel to save space and money and so the chips would actually end up in the chip tray rather than just around the floor.

The difference in relief between the two is that metric nominally has radial roots and standard nominally has flat roots. No one gives a shit though because the cutter will have a radius on it as soon as contact is made (if it was ground with a flat at all).

Carbide needs to go as fast as it can go. It is not strong, just very hard. If you plunge it into a predrilled hole equal or less diameter it will break. Plus center cutting mills are way more expensive. Fastest and cheapest is flat bottom drill, even if you have to grind it yourself.

>>2232933
If you are really dead set on this, you might be able to bore out a 1.5" holder, at a severe cost to rigidity. Would be best to ID grind or hone the bore so you get a good smooth fit. You could probably also use an OD grinder to reduce the shanks on the endmills to fit a 1.5" holder.
>>
>>2232868
It's only a 1/4" hole. I would probably just plunge with an endmill. You can get double sided HSS for about $20 a piece, which I think would be fine if it's a short run and it's not too deep. You're looking at closer to $50 for carbide, but that might be overkill for this guy.
>>
>>2232980
I thought about that but I doubt the od of a 1.5" holder is even much larger than 2", if I bored it out it would more than likely just end up a ring of sheet metal. I would have to actually make it, if I were to actually do it I would probably get a blank arbor with a j taper or shell drive, make the Holder separate, weld it together and then finish to size to make it as concentric as possible.
>>
>>2232708
What kind of shit hole shop do you work at?
>>
>>2233011
The 1.5" holder on McMaster has a 3" outside diameter, but that might be too little.
Just spitballing, but how about getting a 5MT 2" holder and turning the taper down to 3MT to fit into a regular R8 adapter? My gut feeling is that 3MT isn't beefy enough, and it would need to be welded or brazed, but that would almost certainly introduce dimensional changes.
The J taper arbor idea might be the best way to go.

After reading the anons above talk about small talk and being social in the shop, I just had a really weird memory pop up.
Early on when I worked at a different machine shop, the owners son who ran the place was forced to come out and run a machine. His fault for not getting enough warm bodies after someone got fired and another guy quite. He was like 32, so just a bit older than most of the guys.

Its a laid back place with a decent amount of younger guys.
I was just shooting the shit as usual with a coworker, we had been talking about older disney movies, because he was showing his kid his favorite disney movies.
So we got to talking favorite disney movies and characters, kind of talking to other people and asking them their favorite characters.
Its interesting, because every time someone gives you an answer, it just clicks makes sense the different personality types picking certain characters.
Sure its dumb, but shop talk is always dumb.

Well since the bossman was out running a machine and was within distance, we asked him.
He's approachable enough, and it was a move to acknowledge he is out there and sort of downplay it.

Everyone else thought for a second, gave a pretty quick answer and a reason.
Mr. Bossman was dumbfounded. Like he genuinely got a blank look on his face and was speechless, and kept saying what? Idk?
He acting like it was the craziest thing anyone had ever asked him, and he just didnt know what to say.
After a long awkward while, he said "I guess the old steamboat willie mickey mouse"

Its hard to explain how weird the situation was, and how incapable he was of just being a normal human being.
Fitting in shouldnt be that hard, and it just further reiterated the line between the owners and the lowly shop workers
>>
>>2232517
Right before the pandemic hit, I quit a shop.
The owners were retards who refused to replace others who had quit, and the wages werent all that great anyways.
It was the type of shop the hires a lot of young guys with no education or experience, and they fall into the trap thinking they need to be loyal or thinking they cant move anywhere else.

There was like 4 of us who would complain amongst each other all day about the red flags from the ownership.
How everyone wanted to just quit for this reason or another, and "if _____ happens one more time im quitting"

Well the second I job an offer from another machineshop, I dipped.
And I know that another one of the guys quit like a week later to go back to bartending where he made more money, and another guy went and got a job at the local steel mill.

Then the pandemic happened like 3 months later.
I know the shop moved to another location and really downsized. I wouldnt be surprised if it has shut down completely at this point.

am I just slow because it would take me at least an hour problably. you need to square it up, drill the top holes, maybe reaming or boring the bigger ones, drill and tap the back holes, and pocket the other side. it's 7 tools minimum plus an edgefinder for every setup.

>>2233551
Using a mill stop would cut a lot of the time to set up. I'd also suggest using an indicator rather than an edgefinder for picking up origin, especially if it's in the center of the part. Sweep one side and set zero on the indicator and on your mill, move to the over side and sweep again, once you get zero on your indicator, note your position from the zero you just set on your mill, and cut that in half. That is your center point. I hope that makes sense.
Your pocket geometry also looks like it might be impossible to machine.
>>
>>2233655
it's not my part but I think the pocket breaks through to the 3 holes drilled from the top. they are flat bottomed though so you would have to follow with an endmill or something.

Ah, I see. Getting the bottom of the holes flush with the pocket walls might be finicky, but it's doable.

>>2222772
You could have a free sudent version loaded with all the bells and whistles for the price of EAA membership ($40/year) up until recently, but they switched the deal to their new cloud shit for half the price since. The cad part itself works pretty much the same so it's still good for learning and is quite affordable ($100/year with $10 off effectively with EAA membership), but I hear it's rather useless for practical things because you can't save part files locally to take it to a workshop for example.

what's the "best" way to run a face mill? high or medium or low rpm? high doc low ipm or a low doc high ipm? is it normal to sound like a fly cutter where the "thunk" when it takes a cut is spaced out instead of being rapidly one after another as you might expect (maybe one cut revolution vs rpm*# of teeth per rev)?
Its a 3-inch 90° 5 insert face Mill on a half ton 1.5 HP machine, so it's not the biggest thing ever but it's no harbor freight mini mill. I do .02 doc .1 ips 350 rpm in aluminum which works well enough even taking a whole 3 inch cut but it does start to test of the rigidity of the machine especially when it hits an interrupted cut but is otherwise manageable. would that be considered too extreme? I'm asking because I figured hey it's aluminum, more rpm means more gooder, but going up the next gear which is 670 rpm the same exact depth and feed the machine is quite unhappy rigidity wise. power wise it couldn't give a fuck, it's got a mechanical gearbox and an 1800 rpm induction motor so torque isn't an issue, but the headstock wanting to whip back and forth is.

30 min nah, your right about 1-2 hour
im just a hobbyist
maybe some pro can tell me how right or wrong my idea of how to do it is

square stock to dimension 20 - 30 min
indicate side that needs milling 2-3 min
drill hole to depth of one of the 3 holes on the other side so you can get an endmill in there
mill pocket 20-25 min
turn part
indicate 2-3 min
spot 2 min
drill 1 stub 3 min
if high precision needed endmill to depth of nose of of jobber drill 3 min
drill 1 5 min
ream 5 min
spot
stub
endmill to depth of nose of drill bit
stub/endmill again
drill 2 5 min
ream 5 min
3 holes drill 3 10-12 min
I dunno how you would do those flat edges at the ends of the 3 holes into the milled pocket other than a super long skinny endmill
flip part to back
drill procedure there
so maybe more like 3 hours from all the annoying tool changes
thats my estimate from using a small hobby or bridgeport
using something with set offset tool holders and power draw bar would speed things up by a lot

I've been a welder for three years, recently I've landed at this bullshit shop hired me as a stainless tig welder, but there's basically no welding to be done 99% of the time so I've become a button pusher for the machinist running parts on a Haas mill.

it is a PM932 (I'm >>2228846). watching videos on it before I got it everyone seemed to like it, except for one guy who actually ended up getting rid of it and upgrading to a knee because he said it had rigidity issues from it being a square column with such a heavy headstock. I figured because he was the only guy that said that he was just trying to take retard cuts or something and wrote it off. he also had the PM 940 which is a slightly bigger slightly heavier version (1200 lbs). well I guess he wasn't wrong. however it should be said I did decide to yolo it and throw the fucker in overdrive which is just shy of 2,000 RPM, and it seemed pretty happy with it at the same depth and speed except for the inserts or the work getting so hot there was that smell of warmth in the air, so I went down to high 2 which is about 1200 and it's pretty good, still vibrates a bit but it's just a light general vibration in the machine not it trying to shake the floor. there's even a little steel plate bolted to the bottom of the head or the drain plug is for some reason, and starts to sing when taking the cut but I still can't help but feel a machine this heavy with this much power should be able to take a much heftier cut without the column vibrating like a spring.
and yes, I did have the headstock Gibs locked.
>>
>>2234506
oh and the quill, that's locked during the cut too and I have the head right close so I'm only using about an inch and a half of travel max so that should be plenty rigid I think
>>
>>2233839
>670 rpm the same exact depth and feed the machine is quite unhappy
Small machines need more trial and error to find settings that work. It's not even the low mass but often badly fitted gibs and ways which limit rigidity. 3" is already a very big cutter for a half ton machine but should work ok in alu. When you double the spindle rpm you should also double the feed. Which already seems quite low to begin with (0.1ips = 6ipm?). Maybe the inserts are only rubbing because they don't get enough chipload.

>is it normal to sound like a fly cutter
No. It can happen when the inserts are at different heights or there is runout.

I don't have a 3" facemill but i have a less than half ton (RF45) and it does about .120 doc with 12IPM, 600RPM with a 40mm HSS shell mill in alu. I know the z axis has a very bad fit though. Not sure how many teeth probably more than 5.

Take it off that wooden pallet if you can and set the machine on the concrete. That'll help with rigidity. If possible bolt it to the floor too.

wow really? pm says they recommend up to 2.5 for it, i didnt think the extra half inch would make that big of a difference (thats what she said)
>When you double the spindle rpm you should also double the feed.
ok ill give it a shot and try not to yeet an insert or the work into my chest
>Which already seems quite low to begin with (0.1ips = 6ipm?)
yeah it has .1 inch per rev screws and the handle is spinning almost exactly once per second. and it probably is slow but thats what i felt comfortable with when sneaking up to a speed until the machine started to seem unhappy

Cle Line bits are made in South Carolina. Yes, the retail indexes are shit.

All HSS comes from China. All of it. The geometry makes the difference between asian manufacturers

I would do:

Prepare all needed tools: 5min
Edge find vise back and stop: 2min
Mill sides and top of stock: 2min
Drill and tap M3 in on top side: 3min
Deburr and 180° flip part: 1min
Cut bottom to size with measuring: 2-4min
Deburr and flip 90°: 1min
Spot drill all holes: 2min
Use carbide drill for bigger holes/drill and ream: 2min/4min
Drilling small holes slowly so drill doesn't wander off: 4min
Flat bottom drill to right depth: 2min
Flip part 90°: 0.5min
Rough out pocket: 5min
Measure/correct depth: 1min
Finish pocket: 1min
Manual deburr/chamfer: 2min

You can definitely do it in 30min especially if accuracy is not that important. Then you can skip all depth measurement. I just bottom the tool on top off the part, zero my quill DRO and trust that it's going to end up in the right place. That's often good enough unless you need to hit better than 0.05 mm. The same with squaring the stock. I wouldn't do 5 sides in one go in a precision part but for stuff like that a little tool deflection doesn't matter. Edge finding is not that slow but annoying. If i didn't have a vice stop i would make one first before starting the part.

If you don't have flat bottom drills or extra long endmills it immediately at least doubles the time. Also i would do a test piece first to check how much the small drill wanders off.

I wouldn't mind the tool changes. If everything is prepared it's less than 10s for changing the tool in the chuck or under 20s for changing the holder.

In my homeshop i would take an hour because why rush it and i probably had to cut from unsuited stock. Also i wouldn't do it at all without a DRO. That's torture.

how do you change a tool holder in only 20 seconds? it takes me over double that.
>>
>>2234989
If you have a hydraulic draw bar it is something like 20 seconds. If you have to break out the step ladder and use a spanner and the spindle break, that shit takes forever

>>2234765
gotta say, you were right about the feed rate. i cranked up the power feed and now its a monster just tearing through with the same minimal vibration. i did 2000 rpm 30 thou depth about 1.5 inch cut width with the pf dial on 9 (idk the ipm) and it just sailed through. i did it also at 1200 and it was just as good. i even did a 50 thou cut and it ate it up no problem, although i bitched out and turned down the feed to 5.

like i said the ringing is that stupid little plate. im going to line it with silicone or something so it stops.

I can reach the drawbar from my normal working position and have the wrench and toolholders always in reach. If i have to pick up a tool from a cabinet it obviously takes longer. Or if i actually feel something when wiping the taper and wipe it 24 more times and just to be sure. Maybe it's also a thing with the toolholders? I have mostly DIN69871 with a drawbar adapter but also some older ISO40 with cylindrical extensions and a few of them take a lot longer to screw in.

I got r8 collets and it's a pain in the dick. I'm a manlet and there's a 6" spacer under the turret so I have to climb a ladder just to reach the draw bar, then unscrew it, knock it loose with my dead blow, climb back down, grab the new tool, and do it in reverse to put it in.
>>
>>2234582
You can load it in a machine just like an endmill. Some shops use them for deburring cycles after finishing, and I've heard of a guy using one to plunge through a broken tap.
>>2235032
A lot of people, even people who have been machining for decades are stuck in a "low and slow = good" mindset. Sometimes you just need to plow through.
>>
>>2235069
why not get an er collet system or a power drawbar attachment then

>dumb fuck gets set screw stuck and then strips the head trying to unstuck it
>try the old hammer torx bit in trick
>bit fucking snaps when I try to crank it out
>now have to drill out hardened bit + fairly hard set screw
I managed to save it but fuck this was the most stuck shit I've ever run into. usually the drill grabs onto the remains of the screw or at least you can pick them out with an awl but this time I had to run a tap through to recut the threads. lucky there was just enough above where the screw was the tap could pick it up.

Not deal with what, people? Is your goal in life to be an NPC? Trades aren't like the customer service industry where you sit and just put in your time. It's equal parts your life. You get to know the people you work with because, like it or not, they impact your life.

If the new guy walks in and keeps to himself it doesn't sound to me like he wants to learn from the old timers. I get involved with as much as possible to learn the field. Standoffish people are deliberately isolated and less likely to help the rest of the team or pick up slack if unexpectedly shorthanded.

can I use carbide bits to shape/broach gears? I can't really find "shaper bits" and it seems its not even its name because when I go to amazon or other sites, the keyword gives me women's dresses.

can you get it in blue? blue bosh it better then green bosh generally speaking

use a burner labtop or vm if its a program that need better then potato specs

Don't you just take a HSS blank and grind it to whatever shape you need?

this shit look like a toy. find yourself a drill that look like pic related.

Nobody expect you to “really care”, it’s frivolous small talk. Normal human interactions.
It’s very odd when you lack the ability to do so.

It's definitely not suited for any kind of precision work. The head is not very stable around the column and there's nothing you can do about it, and more importantly the chuck has like half to a full millimeter radial play at the end by design: there's a plain deep grove bearing at the bottom and ringless needle bearing at the top, no preload or adjustment or anything. Some people apparently won the tolerances lottery, but mine wobbled like all fuck out of the box. It's not that much of a problem actually since the drill stabilizes itself once it goes in, just don't expect the hole to be at the exact place you want it to. The insides are basically of the corded hand drill and it sounds like one as well.
On the pro side it has quite a bit of oomph, and you can lift it with one hand.

what the fuck are all those bridgeport clones thinking of with continuing this bullshit
I have some protolight small cnc mills that takes these small taper holders and its just a simple lever that pulls the holder up into the spindle
takes 10 seconds
a power drawbar is a big annoying thing to add and they always cost like 1000 bucks
or you can make a bullshit one with a small impact wrench fixtured on the bar end
