Where on earth do you manage to find all of your steel? Not to mention all of your linear parts like slides ball screws and servos!
Im very impressed with your work. Just one question, is that a 10mm pitch ball screw direct driven by a servo motor? If so thats going to have a very fast rapids

I buy steel from my neighbour. It costs about $0.75/kg. The motors for xyz is closed loop stepper motor. The pitch of ball screw is 5mm.
You will cry when you see these :

Now I'm working on the DIY grinding machine. I need a larger size to ground XYZ base before I put the rails and ball screws on.

What is your DIY grinding machine looks a like?

Good lord! The size of those! Dare I ask where you got them?

[khoac3]

A friend bought it for me. It's unused and the size is 45mm, 890mm long. A rail and 2 sliders weights about 17kg. PM if you are interested in having some lol. This project will be started soon.

@asuratman It's H type grinding machine. I don't have the drawing now.

I've been working really hard this week. Here are what I've come up with.





Let's see how it weights...


Vietnamese scale :violin:


Thanks for your interest.

150lbs in the head?!!! You gonna have a spring or counterweight to offset that?

[khoac3]

Yes. I will use counterweight for the Z axis :wave:

Here are the updates:






I tested the speed last night. Z can moves at F2500, 3000 and 4200mm/min.

Outstanding, simply... outstanding!

How fast is that in shoe lengths? [ wink ]

[khoac3]

It's the rapid move. The real cutting feed rate should be much lower than that (chair)

[khoac3]

It's almost finished :wee:
