Diamond 20 CSB II/III

Swiss Type CNC Lathe

Machine Features:

Cross travel sub-spindle :

Cross travel sub-spindle design. The main and sub spindles can work either one at a time or simultaneously for reduced machining duration. This design brings multi-function front and rear machining.


Short remnant material :

With the optional rough material bushing, the remnant material can be 50mm (depending on the part length).


Raw material machining :

0.1mm material tolerance can be achieved by using the Rough material bushing.


Replaceable fixed / Driven toolholder set :

The 4 pc back stationary / driven tool holder is replaced by the newly designed replaceable fixed tool holder or driven tool holder. This enables increased tooling fiexibility.
