2-axis milling head DBDP-310

flange-mountedelectric

Introduction
The DBDP-310 is a compact two-axis milling head with an integrated electric spindle. It reduces flange diameter and product weight while providing spindle speeds up to 20,000 rpm. The compact clamping mechanism and HSK-A63 tool interface are designed for machines that require responsive two-axis positioning, high torque density and high-speed surface finishing. Water cooling ensures thermal stability and consistent machining accuracy.
