Description
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.
