2-axis milling head DBDB-335

flange-mountedelectric

Introduction
This DBDB-335 version balances strong axis holding with higher spindle speed. Dual-side braking reinforces the swing axis, while the 18,000 rpm HSK-A63 spindle supports finish milling after heavier indexed or simultaneous five-axis cutting stages.
