Z axis unit


Microlab ISO 40 spindle cartridge.

Model NPRG4 8000 RPM ISO grippers dual bearings.

 

The spindle unit is ordered with a surrounding coolant unit.

This means that the coolant is sprayed from all directions to the toolholder.

The spindle has a redesigned blocking mechanism now with a 4 edged disc.
With a 608 bearing pushed in the slot, you can lock it.
If you lock it while turning, it can jump out without any damage. 

The new Z Axis assembly designed in Alibre Design Pro.
