Polygim DIAMOND 20 CSB III-S Swiss Type CNC Lathe (DIAMOND 20 CSB III-S)

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 parts 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 flexibility.
