I don't know what I qualify as. I got trained OTJ to operate mills to the point of manually editing some code and even programming our lathe, but pretty much just stuff directly related to simple operation. Everyone else left so now I also cut my own material and decide when/what to run but it's all the same production parts, not the one-off jobs the boss does. Sadly, these other tasks, including kitting and shipping, mean I have very little time for idle phone browsing.

$16/hr to do this all day baby , only draw back is that bitch I gotta give child support to

being trained as manual machinist and fuck my back is killing me. They train me on the machine that no one uses because it doesn't have autofeed, some polish antiquity looking bullshit. It makes cool stuff but god damn. Going to have full on popeye arms at the end of this.I'm almost done with my starter projects and will have time for some g-jobs. Anything cool I should make while I have free time and a lathe? (something I could take out of work in a backpack)

I rarely get to use our lathe, and i know a place that has a cnc lathe i might be able to get access to so i just started making shit in CAD and getting the files ready.
I made a centre punch already(manually), it doesnt take long.
If you have access to a welder you could make more shit like a bench vice, F clamps etc. which i made in a course before i started my trade.

>coins, if you have access to a router/laser/mill you could make cool ones

>slide hammer and accessories.

More ideas would be cool as i have access to a mill and shit as well.
I have no training for picrel, hopefully it doesnt explode if i get a chance to try it. i'll add a knurling tool if possible if it works well without.

My local makerspace has a Bridgeport step pulley clone that has an extra lever, and I cannot find any manuals or references on what it actually does. Anyone have any idea what it's for?

Pic related. On the background is the official documentation from Bridgeport, which is the grey machine.

>>2923407

Why are machinists like this? The software basically does everything for you anyways.

>>2922997

>>2923411
When they pay you $18/hr you have the write the program by hand

But you’re only allowed to program if the engineer orders 10 or more

If he only orders like 5, then you have to make it on the Bridgeport or the lathe

Not really machinist question but maybe someone here can help
The mist separator on the CMM is leaking from the bowl. Does the entire unit need replacing or just the filter element?

>>2923693
Depends how it's leaking, but you can usually get replacement bowls. Is it the drain on the bottom that's leaking, or is it seeping from the top?

>>2923693
The filter isn't likely clogged as they auto drain by design. But you can replace it if you feel like it. Oil mist separators are likely to leak pretty consistently if running in a humid environment.

That whole unit (SMC AFM20-F02C) only costs $62 direct or through distributors. The filter is around $14.
https://www.smcpneumatics.com/AFM20-F02C-A.html

If it's a Zeiss machine I would keep a spare handy as their porous pad air cushion system is a lot more delicate than competing brands.

nta, but I do need a small CNC mill for my business. Is this the right thread to ask for recommendations?

We probably won't ever be making anything larger than 10" in one direction and 4" in either other directions. Usually only within a 3" cube. Mostly cutting aluminum, maybe steel too.

Do you have any recommendations for a good starter mill under $800? Doesn't need to be fancy, just work. Precision probably on the scale of 0.2-0.4mm

>>2923357
Bro idk I always grind my center punches out of old broken or worn out taps. Steel is already heat treated and it doesn't get any better than HSS for durability.
If I let you use my CNC lathe and you would waste my time, your time, machine time and wear for a fucking center punch you could buy for 5$ in the store I would kick you out of my shop instantly.

>>2925795
>nta, but I do need a small CNC mill for my business. Is this the right thread to ask for recommendations?
as good as you get in 4chins i guess
just please dont listen to sieg
which steel? how complex is the geometry? 3 axis cnc?
how fast it needs to be?
those tolerances are thrash, so that at least is good, but still, that is kinda low budget desu , unless it can be done with a chang special mill router
are you in the usa? i guess?

>>2925797
The CNC lathe never gets used, it's at a training org. (aimed towards troublesome kids) gathering dust, it might've been donated. i thought of it as an opportunity to learn myself, and leave some code for the instructor to show students. CNC is out of scope for the training they do, but maybe it will get some kids interested seeing it make something. They do learn about heat treating there as well.
Luckily my boss is chill and lets us use the tools/machines/consumables for personal projects as long as they arent in use/needed.

>>2925828
I don't know steels, but honestly certain stainless steels would be ideal.
Geometries will be simple, only every milling one side, flipping, and milling the other side.
I don't have a sense of speed yet, but I'd like to be able to mill away a 3" cube in 3 hours.
Yes, I'm in the USA.

I really just need a mill that works and can get me introduced. It doesn't have to be the best. We can get a nicer one later on, once we're more familiar with it.

>>2925869
>Geometries will be simple
have you considered a non cnc?
i mean depends on where you are but you could get a pretty decent second hand old mill built like a tank for that price instead of a chinese basic cnc router, strap a digital readout and you will have a versatile but manual machine
the lower end on cncs are kinda bad

>>2925930
The majority of parts are rotationally symmetrical. Like, if we had a good metal lathe then we would be set. I was assuming that a mill would be cheaper. Could you get a mill with a base that does full rotations around the milling bit?

>the lower end on cncs are kinda bad
Thank you for the tip

>>2926103
anon then get a lathe... no they are not necessarily more expensive, where i am from you get them cheaper
and 3 inch parts can be milled in a lathe mounting them in the toolholder
look on craiglist where you are and cities near, if search around enough, you probably will be surprised, people showed what they scored on past threads. you may need to travel a little for a good deal desu!
fucking sieg didnt link past threads
and if not you can get basic lathes in that budget in aliexpress, and some anons mentioned that those same chinese ones are sold in your local hardware big chains

You could *maybe* get a passable manual mill for that price for those tolerances, but for CNC you need at least another zero.

its usually opposite that. a semi functional cnc is nearly free save for the rigging. either way 8 bills is low buck shit. i sold a fully operational and tooled bridgeport cnc for $2k a couple years ago and it took over a month to sell. i finally got a guy to buy it if i delivered it (paid add'l $500). it was a clean mid 90s machine with low hours but the control died so i put mach3 on it. made good parts but couldnt rigid tap and no toolchanger sucked
picel is a mechanically superior machine because it has more z travel. anons $800 would buy it i bet but expect 50/50 to have it work when powered up due to sitting. i wouldnt hesitate to retrofit the control if freetime was cheap/available

>>2926271
If his budget isn't even $1000, he absolutely doesn't have the money or hookups for a 3-phase, proper mill after factoring in the tooling and repairs.

>>2926272
>he absolutely doesn't have the money or hookups
i dont doubt it on this larp site. its nothing to need a $75 carbide endmill and thats just a single cutter. then you fat finger the 0 and auger it in and hope you had a spare bought so youre not waiting days for a replacement in the mail

Say hypothetically you were a casual crossdresser or trans woman, what kind of fashion would be safety conscious as a machine operator. Tied up hair and jeans and no loose clothing is key right

Machinechads - I need a few small parts tapped but don't want to get it thread milled and pay my guy hundreds to buy the tool and labour.

How can I do this myself?
Metal: sterling silver (cast with 1.6mm dia holes)
Need to tap for M2 screws. 0.4mm pitch
M2 has a 1.567mm minor diameter, 2.0mm major diameter.
What exact taps do I need because I see a few different types out there.

>>2927027
Also I just realised that this cast may fail due to the 0.5mm clearance between the hole and top face.

>>2927027
>>2927028
you can always buy a set of taps, the kind that allows use 2 or 3 taps to do a single thread, so you can thread until the end, this way you could get a thickness of 0,8mm instead of 0,5. you will probably need to use also a mill flute to flat the drill cone
as a reference, https://www.mcmaster.com/8305A511/
you may need to grind the end of the taps, desu, finding one clean is not that easy
you may also only use one tap, in that case you need the bottoming chamfer one

>>2927027
You need a form tap, bottoming so it’s got no lead in. Make sure your hole size is correct for forming threads before doing it

>>2927033
>you may need to grind the end of the taps
This was my plan. I bought these and will pray I don't snap these ebay jobbers in the hole.

>>2927035
that should work on silver, i guess. general advise, dont do only 2 steps on difficult materials
but as i said then cast a little less depth and the use a end mill as a flat head drill to finish it https://www.mcmaster.com/products/end-mills/?s=1.6+mm+end+mills
(i am from the eu, but if mcmaster website is not the best one to use as a reference, i dont know what would be)

Happened to me years ago, i couldnt have been happier pushing button, but as time went on i started getting annoyed at the programs running slow so i started pissing off the programmer and soon he turned into an office fag and i was left with 3 cnc mills to program and service.
I had young kids fresh out of highschool pushing buttons and taught them everything i knew so they take on more responsibility.
Pay increase was good but it wasnt what i wanted.
I wish i kept my mouth shut and pretended to be retarded so they feel sorry for me

Also, if it doesnt break, half a mm is so thin the tap might drill the hole trough by accident

>>2922997
You are lying. You have to set the tool heights and zero in stock.
And you probably have a dedicated programmer, meaning you probably have to check the program you are about to run.
You already know basic g code and can predict a mill break based on the sound it makes.
You are slowly getting experience and soon you will get more and more responsibilities at work and now you feel like you miss the simpler days.

Your superiors dont want to buy new end mills, ''shells'' for shell mills, nor do they pay for sharpening end mills, therefor you are tasked for performing the same while having nothing to perform for, which either means, you take bullnose mills and program I machining in solid cam for taking down large depths, which further means, you are running out of stock metal as well
You also mention debts, the company is in deep debt to metal providers, endmill providers, end mill sharpeners and probably state funded electricity providers, not to mention the coolant or maintenance
and you type as a retard, trying to joke your way out of your misery
You should quit, try being a bartender, driver, anything, for at least half a year but search for machining while you are at it.
It never ends well when you work as a machinist that doesnt have access to tools, they dont take you seriously no matter what magic trick you pull out your ass, the company you work for is going under.

so i need to do this dive with a 55/64 four flute endmill to widen a through-hole, the problem is i only have a drill press with a jacobs taper 3 and the ER32 collet chuck only has a morse 2 so basicall i want a sleeve that fits into the female jacobs 3 but also takes the morse 2, somehow there are only dual male arbors on the interwebs, wat do

something funky is going to find out
some of you guys are alright
dont go to the hardware store tommorrow
may the machine god of stiction bless you

Which steel do i use for wood chipper blades?
Im building one like this:
https://www.youtube.com/watch?v=3WiShUSggas

I did some calculations and some reading, i found out the angle dimensions of the entire blade, the shaft is 50x50 (mm) where its square and rounded 30 in diameter on the sides, a tractor is going to power it instead of electric motor, so it has a lot more torque on 300RPM.
Since you people go trough a lot of steel, which one do i use that wont bend or dull easily (the wood it shreds wont be tough nor dry)?
Have in mind, in the video, the man didnt put any fixed blade on the bottom, its just all flat, i on the other hand have placed a fixed knife made out of 1.2379 steel, i have no idea why was it expensive or praised by the machinist guy that milled it into shape for me, i guess its tough, he recommended not to make the spinning blades out of it because if it runs into something, it explodes like a grenade and its too dangerous.
I dont plan to heat treat the blades either, id rather have them bend than to have them fly in pieces everywhere if something gets caught in the chipper.
Note that i have absolutely no idea how steel is classified nor the names or markings, i only know the requirements for steels characteristics and price ofcourse, meaning i need it cheap.

>>2923569

I could tell from the thumbnail its a bridgeport

>>2923146

Thats why i collect unemployment and pay my support off that while making 20$ cash an hour doing contract flooring on the sider

>>2928363
>1.2379 steel
German fag spotted. That's D2, it's a high end tool steel. Very abrasion resistant so it makes good knives, but the as the guy said it's not very shock resistant.
>I dont plan to heat treat the blades either
You'll be sharpening them all the time then, green wood is harder to cut. A2 tool steel has pretty good impact resistance and you can harden it reasonably with a torch, or O1 steel with a torch and some oil. Both are pretty cheap.

>>2928430
How about 1.2080 dont know how much that is in hamburgers, 4957 google says?
I can get it for free if I can trace the plate, it has holes and stuff on it, I think I can get 4 blades, do you have a chart by any chance, table i could use that translates the standards for steel?

>>2928439
That's D3, same issues. D series tool steels are also very difficult to machine because they just eat tooling. If you don't harden it, it shouldn't shatter, but annealed D2/3 is relatively soft, just stupid fucking tough so it might bend from all the impacts. You'll want the blades at least 50 Rockwell C hard regardless of alloy, or they'll wear out crazy fast. Hitting specific hardnesses without special equipment can be difficult though. I wouldn't worry about shattering that much however, the hardest thing you'll probably hit in what I'm assuming is raw timber/tree trimmings would be nails, which any of these steels should go right through, or stall the motor out. It'll mess up the blade but as long as you're not chucking rocks in the thing and are wearing proper PPE, you should be fine.
A2 is 1.2363
O1 is 1.2510

>>2928439
Prices vary drastically from the US to Europe, but based on prices in the US, you should be able to get enough A2/O1 for this for under 150 Euros.

I made a decision to go with D3, I made some inquiry where they heat treat metal around me, they charge by weight, not expensive at all and the material is free for once.
This is how much it will stick out, M16 hex screws, a ribbed plate under their heads instead of washers, it wont go anywhere, if something was to snap, I will put some holes on the front for another plate at the entrance and leave some 50 mm at the bottom, I highly doubt I will want to put a branch that thick in, the blades start cutting at 30.
Thank you for your input.

>>2928509
One more thing
I will tomorrow cut the 4 plates, its 16mm thick, i need to plane it down to 12.5, or even more since the heat treating will bend them, 12 is final, I can do it on the old precision grinder after heat treating.
Before that, I can cut the plates, shape them on the planer, maybe grind them on the sides, the length is important later on, use the press drill and files to make the pockets for the bolts and all i have left before heat treating is the angle, which i can't do myself, I will need the CNC guy, I wouldnt like to make him do more than 2 hours, half an hour a blade, we exchange services and rarely dabble in money.
From my days as a button pusher, I remember that ball mills are rarely used, but for this they would be perfect.
If this metal is tough on tooling, would it make more sense to save time and the tooling, for the mill to cut on X axis while stepping both to Y- and Z-, or immediately go Y-Z- and step by X?
I can make a model, I think I can program it too, to save all the preparation and stuff.
And the cnc guy is a psychopath, he will ramp it up each pass if the program is good.
He works on a HURCO machine.

You can make a knife edge on a belt grinder, knife makers do it all the time with hand forged knives out of rail road spikes or car springs

>>2928564
How long does it take? Lets say his knife is 8 inches wide, angle at 30 degrees.
I can do that with a single half inch ball mill, on 2 such knives in the same vice
He wants it on D3, so i choose 2 flute, 4500 rpm, down up down left up down left by a thou on climb, quadruple on conventional, max feed to see what happens, im talking G0
Takes 15 minutes tops, 6 minutes setup if I am in the mood.

Why arent there any black people in CNC buisness in USA at least?

>>2929259
I've seen 2 black guys in my 10 years, including giving interviews.
One was a pissy baby that allegedly wanted to be a machinist, but cried about every little paper cut and minor burn (he was deburring some aluminum with a countersink on a slow drill press and a chip hit his hand, we took actual injuries seriously.)
The other dude was okay at first, but eventually had huge issues with authority and just didn't feel like doing the work he was given, and refused to take responsibility when he fucked things up. Towards the end, there was a job he totally screwed three times in a row just by not caring, and thought scrapping a dozen $400 plates wasn't a big deal. He also tried to get unemployment after leaving voluntarily, and threatened to sue for racial discrimination.

>>2929904
>he thinks knowing what the codes mean is the hard part
Machining is like any skilled trade. No individual part of it is "hard", the hard part comes from the sheer amount of random technical knowledge and experience it requires to actually be good at it and be able to to tell what's causing an issue and fix it. It's basically that meme story of charging $1000 to smack a machine with a hammer and it being $10 to smack it and $990 for knowing where and how to smack it.

>>2929904
g code is the fucking easy part of using a cnc machine

I'm not normally one to be Safety Sally over every little thing, but that's sincerely very dangerous anon, especially for something like an out of round/interrupted flame cut. It would be more setup, but a better way to do this would be to have another plate with some good surface area to stick in the chuck with some 1/4-5/16 threaded holes and then drill and countersink your actual part.

For years I thought to anodize aluminum you use electrical currents to control the end color result. Turns out that's titanium, and for aluminum you just soak it in a pot of dye for a while. What a gyp.

yeah mystery lifted, it turned out that all what was missing on the taper was pic rel, the collet chuck had a short jacobs taper and the main taper shaft was regular morse2 size, my milling operation in the drill press worked out well

I assume your the same fag...
There are youtube vids... Really easy.
There are textbooks idk what your native language is but there are always some (prob english ig).
Id recomend to pick up a "standard compendium" (Normenauszug in german), a book with the most importand and widely used standards, its more for creating the drawing but it has all the info you need.

There are also 2 general standards in use
The old one ISO 2768
And the newer harder one ISO 8015

Officialy the old one isnt used anymore but the industry will tell you smt else

If there is a specific case you need to know you can also post a pic here. But pls 1 post not 4

Yes technical drawing is correct.
I also wish you had a higher IQ...

I don't want to go back. After being surrounded with real machinists I know where I need to be. I don't know if its just the culture of the company but production is like a hellscape of drama and bitching and whining and I don't think I'll be able to deal with it after seeing the promised land.

I figured I would just put it on ebay and accept the ridiculous sale fee in exchange for not dealing with 100 retards a day offering to trade for their PS5 or beat to shit dodge dart or whatever, and also having precisely one person come to my house to pick it up. Is selling something this big inexpensive on eBay safe for the seller?

i find myself interacting with him that often. in fact, sometimes he comes around looking for work to do because we're busy just chugging away at our machines.

maybe he could be take more time to make sure he does his programs right the first time -- so that WE dont have to fix them -- a second time.

You used to be able to markup your paper drawing or the foeeman would even get red ink all over it saying how fucked the engineer is and what all the tolerances actually are.

Carbide tooling for hobby use is retarded, one wrong move and you destroy the sharpened point on a carbide tool and then how the fuck are you supposed to re-sharpen it? Also it still wears out, even if slower than HSS and then you're left with expensive scrap.

HSS tooling can be re-sharpened on a bench grinder or even a little dremel mounted in a vise. Learning how to do it takes a little bit of practice, but once you get it you can work shitty materials like solid stainless steel which wear down tools within minutes.

It’s cheap because you need balanced holders in an odd size

>bt35

So youre either buying Chinese holders or used ones that may have been mistreated

Bt30 and bt40 are more common

Local community college doesn't even have manual machines here. They'll teach you CNC only. And the local makerspace only has a CNC machine that can engrave wood, and 2x 3D printers for some reason. Membership fee is only 30 bucks a year though so you get what you pay for I guess.

>>2947402
This was me and I was actually wrong. The local makerspace DOES have machine tools, manual mill (bridgeport) and lathe (not sure what brand/model) as well as a Grizzly CNC mill. Apparently in good shape according to a friend who's a member too. They just don't advertise them because they don't do training with them, so only people who are already qualified are able to use them. It's also 169/yr.

>>2969785
That's a shame. Mine has a decent setup, 6 mills (an actual Bridgeport and a variety of clones) and 7 lathes (4 of which are new Jets that are garbage and are going to be returned for something else shortly) as well as a manual surface grinder and a bunch of drill presses etc., and then on the CNC side we've got I think 3 mills of various sizes (plus a little benchtop one for basic training) and a lathe or two, all Haas. The school is also about to do an $8M 13,000 sq ft expansion that will add more of both kinds of machines as well.

is the turdmach fad over?

I used to work around* CNC's, going to get my personal CNC this year.
Depends on production quantity/times.
Genmitsu 3030/3018, anolex, etc. can definetly get what you need, given enough time.
Otherwise you're probably looking at manual mills.
If someone tells you that benchtop CNC can't do aluminum/steel at decent™ tolerances, you can safely ignore them.

You know how they pay us to only push the green button and nothing else?

D-do you guys ever wonder what those other buttons do?

I want to push that “feed rate +” button sometimes you guys think they’ll find out?

>>2923159
they were surely dwarves back when they manufactured quality lathes because they're so fucking low, all of them

>>2973623
The new fad is turning your old shitty ender 3 into a wire EDM machine no idea why

>>2925795
get a good quality, used manual mill and do some side jobs, then spend some dollars on a cnc conversion. benchtop mills are toys, mill attachments for the lathe are toys.

God machine operator sounds like a chill job. Go to job, turn on machine, maintain it even if you're into that, hope it doesn't throw errors. Very nice indeed.

>>2975726
>build lathe with sitting in mind because who in their right mind wouldn't if they're gonna be at the machine 8 hours
>Corpofags get the idea that sitting = idling
>"You must stand!"
>Dozens of workers with bad backs now cost taxpayer dollarinos
Maybe.

>>2975880
Was pretty chill, the problem is that you pay stays the same and it turns into … hey set it up on week 2

Then by week 6 you’re starting at surfcam wondering what the difference between wrought aluminum plate and extruded bar is and if 7075 will leave a nice enough finish for the part to be water tight with the dull hss keyway cutter for the o-ring

Pretty soon you’re stressing about dead lines, trying to “just draw it up in Solidworks real quick. Program it, and let me find something to make the fixture out of really fast” for $18/hr

>>2975880
tbf a lot of work on manual lathes wouldn't really be possible sitting, at least with the limited stuff I've done I'm constantly back and forth to the point where having to stand up and sit down over and over again would be impractical. Maybe it'd be different in a factory where you're just doing the same operation over and over again though.

>>2975880
nah, not sitting, but a lot of the levers could be placed 10cm higher up and it'd do wonders for the back, especially when you're threading and you're standing ready to hit the reverse.

my shop hires this type of person frequently as students/trainees. students, fine, they're new and need to be shown how the shop works. i don't expect noobs to come in knowing everything. but holy shit, some of them go for 90 days and STILL don't know, that's the kind of stupid help won't fix. i'm not perfect, no one is, but we're hiring so many goddamned part timers right now that i'm never going to move off my shift and i'm never going to progress since all the training is going to noobs who'll be gone in a year anyway.

to stay on point with programmers: i've had good experiences so far, but mine tend to run shit way too fast and sometimes do the rapid into parts bullshit. more or less though, it's fine especially because the 3 axis lathe i run most of the time is programmed at the machine anyway. when machinists program, it runs right every time

yuropoor here, is it retarded to buy a small CNC under a ton (yes it is) from the 90s ?
X : 245 mm
Y : 140 mm
Z : 240 mm
750W spindle, 30 à 4000 tr/min, ISO25, 220V mono (important for me I can't have three phase 380V/400V)
code G ISO

It says the transfer software is "Fagor", would I be able to use it ? I guess it needs a RS232 connection but that's not a problem, would contemporary software be able to generate programs compatible with it ?

it's so cute and it fits on my trailer.

If i had space for such a thing I'd buy it, if its cheap. It looks like fun.

I know this is an old post but shit, I was reading it and feeling really bad because I couldn't figure out a good way to measure a bearing OD with a dial indicator either.

I'm currently going to school for machining, and it really is kinda depressing watching some of the other students. I'm comfortable with mics (though I always have to slow down and think things through with depths mics) but a lot of my classmates clearly really struggle with them and I've seen a bunch who've given up and just use digital calipers for everything and then fail dimensions with .005 tolerances. We're a couple of terms in now too, it was one thing in manual machining 1 where 90% of students were welders or mechanics who had to take it as part of their degree, but now it's filtered down to the people who are actively trying to become machinists and it's still this bad.

I guess maybe I should see it as a good thing though, if it indicates the average level of people who try to get into this stuff it probably bodes well for my own career prospects.

>>2977787
this at least looks usable compared to some desktop variants frequently shilled on this board
>will contemporary software be able to generate programs compatible with it
very unlikely, you'll have to write a post processor. if you're lucky, someone else already have and have posted it online.

i remember that time well, really fond memories. we used to fill plastic bags with acetylene/oxygen, tape em on a stick and shove them in under the booth while people were welding

so yesterday the shop had an ISO audit and I got interviewed about shop processes and shit, now the team lead has to go though all the CNC programs and make sure that every single one has the correct program revision number in it. hehehe

I was a machine operator for a while, and they kept saying they would train me for programming. But then I kinda just learned on my own making adjustments and all, and they asked me to program for a part. The union rep didn't care for that.

Anyway, I bought a small cnc mil for my garage. For fun.

Fuck Siemens and their dog shit changes they've been pushing out for the last several years in NX. The updated sketcher is pure retarded bullshit. For years they've been trying to gaslight users into thinking that its a better work flow, but anyone who has ever used ANY system knows better.

Point-to-point drilling is faster and more customizable. Given that the new hole making has to process each feature as it's added, this can take for fucking ever when you have hundreds of holes.

The old tool path verification was faster and fewer clicks, especially for simple 2D lathe. Being able to run it while still in the operation dialog is miles better.

But the only other option would be the absolute dog shit that is MasterCam and I do too much 5 axis work to fuck with their planes all day.

I hate software companies so god damn much.

Fagor is a company out of spain that does retro fit controls

good people, good product great support

id find out what control it is exactly see if fagor still supports it and if they do, i'd check for backlash on all the axis, runout of the spindle, clamping force of the drawbar function of the flood coolant system and runout of the spindle and condition do a couple tool changes and see if its decent

then buy

if he wont power it on but "ran fine when i shut it off" id pass no matter how cheap it is

>>2977787
fagor is a good brand, if you can get an original program you should be able to make a posprocesor easily.
those old fagor controls have linux on them, but maybe if they are even older i am not sure, but surely you can access some program inside
there is a dude in freecad forum using one llm to make a postprocesor so he doesnt need to use the proprietary bullshit

Do shills disguised as posters exist on hobby machinist forums? Wanted to find a review on the little machine shop's products and I got overwhelmingly positive opinions on them. When it comes to practical machinist they stone you for mentioning them.

geezers are a peculiar lot
they love to brag to each other when something goes smooth despite how little effort was often involved on their part and its a flex how they could just throw their card down and make it happen
they hate showing the weaknesses of being taken a fool so the ones that got a short stick on junk often stay silent to avoid being torn to shreds by the rabid jackals that are forum regulars
now consider the average oldfuck that has time to type out tool reviews is usually long retired and relegated to subdivision life where his shop is 18 sqft of the garage and the most involved machine work hes done in the past 5 years is drilling out scamazon chinkshit plastic lawnmower wheels for his wifes rolling garden stool because they were 12mm and the bolt was 1/2"
