Simple, Lightweight CNC (VMC)

Last crawled date: 2 years ago

A simple VMC design. Designed for the DIY / home workshop engineer.
Max traverse; X=800 Y=600 Z=700
Motors; 3x Nema34
Ballscrews; Double nutted SFU25-10
Linear rails; HiWin HGR25
Guide blocks; HiWin HGH25
Spindle; Ø100, water cooled, using ER20 collets

Designed to be easy to build using stock aluminium tooling plate. Rigidity comes from bound granite resin.

All component dimensions (ballscrews, linear bearings & motor mounts) are verified from physical units I have in my workshop.

My goals are only for machining lightweight composite tooling boards so don't expect this to be suitable for cutting steel.

If you'd like any help in adapting this design or have any questions please get in touch.

I'm a professional tooling design & manufacturing engineer with over 30 years experience. I've only just entered the world of home CNC and automation and have a large CNC bridge mill (using bound granite frame) currently under construction.
