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.

6 pcs cross working driven tool holder
4 pcs I.D. stationary tool holder
3 pcs front working driven tool holder
3 pcs back working driven tool holder
