There has been a minor upgrades to my CNC since I last posted. Had a bit of a re-design courtesy of my brother.


Mods:
1. It now has 5 axises for machining cad wax
2. Steppers have been replaced for DC Servos.
3. Linear rails
4. Gantry upgrade.
5. 270mm Z travel (instead of 90mm)
6. Automatic Tool Chamger.  





My brother modified a standard 2.2kw Chinese spindle to be an air operated ATC spindle. It takes a "cartridge" which uses a C1 collet. These are good for cutters up to 1/4" shank.
The cartridge can be removed and the standard ER11 collets can be used for manual tool changes if required.


Cheers.
