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.

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.

>chess set, i was thinking brass and maybe nickle plate one set?
>coins, if you have access to a router/laser/mill you could make cool ones
>tap wrench
>slide hammer and accessories.
>custom chuck key
>spinning top
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.

>>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

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

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

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.

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

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.

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.

>>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.

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.

>>2928528
You cant make shit, youre using solidcam and you have no idea where to pit the coordinate center or how.

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.

What is the biggest size indexable face mill you can reliably use on a bridgeport style mill (r8 taper)?
Are there any good cheap chinkshit endmills/face mills on ali? Ive had pretty good performance out of the Deskar stuff on the lathe I bought a while back

>>2929718
>biggest
why?
2.5"/60mm any bigger will just hyper display any slop in the mill and mis tram on the head

>>2929721
>why
I don't want to buy one too big

I have a lot of old HSS endmills but most of them are double sided and I don't have collet's for anything bigger than I think 3/4"
Im not even sure I could fit a 3/4" double sided endmill in a r8 collet

why doesn't this field pay more

>>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
the only difficult part of coding is the non standards shit like needing to use macros or other not well documented functions

>>2929718
Not a facemill, but you can fit a pretty big fly cutter on one.

Every actual review I've seen of CloudNC is that anything more complicated than a plate with some thru holes requires you to redo half the program, and modify most of the parameters it spits out.

its been more than 10 years... if i am not mixing machines, bc we had from many companies, you cannot mix third party hardware or mod many things with it
basically we researched how do do shit cheaper, like trying to use alumina brush in a powered tool in the lathe instead of moving the part to a cylindrical grinder.
Or trying to learn how to machine newer materials to be used by the companies.
Trying new tools for the tool manufacturer, that kind of stuff
There were people trying new techniques of manufacturing like laser sintering and shit

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

>>2934607
Yeah that piece is mainly for lathe tailstocks, there's a rod inside that pushes on that to break the taper lock when you back off the stock all the way.

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.
That and programming, setting up, and making a part start to finish is an amazing fucking feeling.

No /emg/ so I'll ask you fucks. I have a 12x36 lathe I'm looking to sell and I don't want to do craigslist/marketplace/whatever because I don't want a whole bunch of random assholes coming to my house and scoping out my tools and bikes and shit. 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 know at least in the past their and PayPal side with the buyer 99% of the time and can completely fuck over sellers for literally no reason and obviously I don't want that to happen for a several thousand dollar sale.

Smallest nozzle size you can get is 0.1mm which will have clear layer lines when inspected closely. For what looks to be a high end product they’d have to be hand finished, obviously not particularly difficult.

>>2942566
Unless you raise the nozzle size by a lot, "intentionaly" creating the layer lines for designe reasons.
Then it becomes modern art and is accepted again

You can also heat and bend a lot of plastics to get those shapes, then glue the 2 parts with a strong adhesieve

those can be operated manually, like with a remote thingy. of course is the motors making the movements, but still, you can do fine adjustments that way

My local one is actually decent for what it does have, nice woodworking setup along with welding/fab and blacksmithing, but they have no machine tools at all.
