Make a special hexagonal sleeve

[a smile]

Start with 3D drawings, assemble simulations

Use a thick-walled tube

Material 42crmo, size: 60*25*100

Lathe into short tube (inside and outside turning), EDM wire cut hexagonal

I think it's not perfect production, it's not perfect design, it's not conducive to production, it's not beautiful, I'll redesign it and make it -----

How did you make the hexagonal hole?

How did you make the hexagonal hole?

He was working on an EDM machcine in another post. It looks like to me he has it working. The second photo looks like the hexagon is being cut on the EDM.

Ah - that makes sense - I couldn't work it out on my phone - the wire became invisible. Desktop FTW.

EDM is like magic to me...

Magic I want.

It feels weird after the thread is done. The first is not beautiful enough, and the second is not suitable for batch processing.

Change the design, redraw the drawings

Start with wire-cut EDM

The center line of the hexagon is used as the base to reprocess the outer circle Add external thread M54*1

Horizontal milling shaft index drilling--6.8mm Double punch16mm

M8 threaded spring bead

Plug tight fit, strong pressing together

,
Make a big nut M54*1, vertical milling curved teeth to increase the friction, I do not know its specific name, anyone can give it a name?

I will continue to optimize the design until it is more reasonable and more beautiful, and I have EDM two reserve parts（It also helps me verify the stability of the modified EDM machine）

You do nice work! I like your furry "inspector".

I'm still trying to figure out what it's for and how it will be used.

@kevin.decelles can your home brew EDM cut a hex shape like @a smile is doing here?
