Anyone know much about the poles they're handling? I imagine they control the mechanical power somehow.

so continuation from other thread, i found a wiring diagram (still havent set up the wiring yet)
can anyone decode this and just tell me which ones are the main power leads? after that i dont need to worry about the control wires since i can just control the motor with the vfd
motor says it can do 2 or 4 pole

Did my first work with aluminum and carbide insert tooling this week. I think I'm doing ok given I'm working with clapped machines and iffy tooling. (Decent 5-flute shell mill, but we're only allowed to replace inserts if they're actually chipped/broken, so I'm working with a mix of new and worn inserts.) Also holy fuck this shit scratches if you even look at it funny, real pain in the ass.

Is 50-75sfm not reasonable for cobalt drills on 304? Today my 17/64 drill ran through something like 15 holes on 304, then it started glowing.I'm the guy who broke a tap on this same part on the last thread. For anyone who finds themselves in that position, turns out the tap-disintegrating carbide drill bits really work. Saved a ~$1200 part.

I'm milling some holes into the faceplate of an instrument enclosure and it's 'foaming up' as the mill is making passes. Pretty sure it's some kind of aluminum. I'm re-running the program to clean it up but still the foamed metal is bulging out over the edges and making cleanup a real pain.Is this something I can fix with a different feed and speed or is it just shitty aluminum?

I want to get into machining as a hobby. Im debating if I should go the self taught route or get certified at the local technical college.
The college seems pretty cheap, less than $4k for the whole program and it's pay as you go.
Not sure if it'll be worth it, but I imagine having the guidance and all the tools would be better than buying stuff myself.

I ended up going with these HSS boring bars instead of the solid carbide ones mainly because the carbide one was like $30 while these HSS ones were $25 and come with a set of inserts that were $20 if I tried to buy them separate.I guess ill see how they work out

I need to replace three solid pins on a cheap 22lr 1950s revolver. It holds the trigger guard, the trigger, and the sear lever on. They are not case hardened, just blued.
They are bent, peened, and mangled to fuck so I cant imagine them being super hard.What steel should I make them out of?
I have hardness files at work and I may test that to see.

Since we're on the subject of tooling, my instructor recommended that I get my own lathe tool kit. I was looking at the $150ish Shars ones but I'm not sure which size and insert to get. They'll be used on 13x40 manual lathes with quick-change posts that can hold up to a 1/2" tool (actually a little more but 1/2" is a safe limit) as well as maybe Haas CNC lathes later on, and will be used for cutting steel and aluminum. Any recommendations?

Been learning the ropes pretty well but one thing I still struggle with is doing good length measurements over the z axis on a machine too. For example you have a 4 inches long part with a 2 inches diameter. But you need a 1 inches diameter for 2 inches of length. I'm usually off by double digit decimal which is not good at all. I've been trying to find video on proper zeroing then doing the right length but I'm having no luck finding them. Any help here maybe? I suspect I take a little too much metal when I zero but I am unsure where the cutting tool should be to start the measurement too

Because im having serous doubts any place would have a different type of boss
Mind you, i dont work at places that have cameras or hr, nor would i ever work if those were the conditions
I can go to a place that only does soft steel plates, large ones, but its mostly 2d programming the type you can code on a machine itself and calculate the offsets to strike the tolerances if any are needed
I dont even care about money anymore, all i care is to get rid of boomer eyes and pressure that those that have no clue about milling metal get by watching youtubers and looking at simulations on cad software
I like my job, but i want to be left alone despite deadlines and problems which i myself manage with

I also managed to hit tolerances to a micron, had videos of the probing as proof on meetings where we were accused of jacking off instead of working
Nobody looked at the slideshow or listened to the presentation i and 2 others prepared
They just switched the subject to us smoking and playing phone games
Then accused of or coming late, 5 to 15 minutes
Then to wasting carbide (we take all broken carbide for ourselves and sell it)

How would I go about mounting a piece of aluminum rod 50mm in diameter and 150mm in length to the spindle of a small 200kg bench lathe?
Just mounting it in the 125mm chuck seems a bit iffy.I'm trying to do some small scale production so I've been thinking if I could come up with a custom collet solution but seems really difficult to keep it within budget.

I didn't like how big the available case options for calipers all are so I designed and prototyped a custom holster today. They were just gonna be a protector for inside a box or bag but I figured I'd add a clip and try that out. Need to fix a few dimensions and smooth out the aesthetics but it works pretty well. I'll throw the final .stls up somewhere (clip and no clip versions) if people are interested. Made to fit the basic Mitutoyos everybody has but they might fit some other ones as well.

hello machineGODS. does picrel look reasonable to mill? it's 250x150x20 mm aluminium. fins are 4 mm, grooves are 6 mm, so a 6 mm mill should see an aspect ratio of just over 3:1
this is for passive cooling for a Peltier thing. multiple plates can bolt together to get more thermal mass, like in the lower part of the picture where four plates are stacked. the slots in the corners are so that it can be bolted to either metric or imperial optical tables
the big holes are M6, not tapped
the small holes are M3, tapped. is an aspect ratio of almost 7:1 unreasonable?
