Post Your Complicated Machining Pics!

I am curious what other students have managed to machine in house, post pics here!

Inline skate wheel and molds, two setups in the 3-axis mill for the hub. The spokes are 20 thou at the thinnest point and 0.04lbs.

This was not made by a student but it was the 2nd part we made on the tormach!

(Reuploaded because the first images were of the scrap parts)

Some work of mine from my time at Team 696. All pieces done on our Haas Super Mini Mill 2 and programmed in Autodesk Inventor.

SDS Mk4 Motor spacers (machined in house since we forgot to order, made 20 in about 6 hours and saved some money too)

Latch for our 2022 climber (helped us hit a 2.5 second Traversal climb)

Shooter mount for our 2022 robot. ~90% material removal from raw stock, took 4 setups to reach all geometry

Vesa mount adapter for a non-vesa compatible monitor.

Engine mounting plate for a personal project. ~10"x12"

Curious how you are holding for the 2nd op…
Excellent job!

For the first prototype we held it with tabs to make it simple, then finished the OD of the hub on a lathe, there is space on the hub for 8 threads to attach it to a fixture for second op.IMG_20220626_200233160_HDR|666x500

Big fan of the adaptive 3D forming. I love how you curled the edges for added stiffness!

Probably the most difficult part I’ve ever machined:

(Actually just my first hand-coded part as a student: an MDF initials block)

Yeah, friction milling is great. for some reason not as widely used in industry as friction drilling for some reason though

A majority of (all? probably all) credit to @Andy_A


Rework inserts for a MEMS printhead machined from carbon.


Captive screw for a special fixture.


Special lathe tool for absurd L:D turning.


Water neck for my racecar, this required four setups and some long reaches.

More adventures in work holding:

Though, in fairness, I bought the penny specifically for these sort of threads.

A Lilliputian hand!

what if it’s Brobdingnagian?

Then the penny would be a Brobdingnagian penny x 10 and the parts sitting on it would not be very impressive! :stuck_out_tongue_closed_eyes:

To put some numbers on this: the largest hole is tapped for 0-80, the middle hole is for a 1/32 (?) pin, and the smallest hole, .013in, is barely visible.

It was VERY hard to mill those curve profiles into the 2x1 :stuck_out_tongue_winking_eye:
(The result of 2 Regionals and 3 offseasons and numerous hours of practice)
Winning alliance @ Red Stick Rumble with those. Didn’t notice until right before eliminations.


3 piece roller pinion gear for our turret with matching 3mm locating pins and holes milled into the ends. Visible near the button cap screw.

Not really a complex part, but it was a finicky thing to get the fit just so, took forever to make and I think it’s a pretty good example of ‘dog boning’ sharp inside corners.

It’s a combination wrench that fits the very oddball hex on the import vise the Tormach came with, and the square end of the drawbar. It’s my favorite shop made tool. Most Skookum.
