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.

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.

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.
also

>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.

The mist separator on the CMM is leaking from the bowl. Does the entire unit need replacing or just the filter element?

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?

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.

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

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.

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.

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.

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?

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

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)

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

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

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.

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.

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.

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?

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

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.

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.

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.

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.

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
