Introduction
Diamond II Series
20B II /20CSB II /32B II /32CSB II /42B II /42CSBII
- 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.
