Overview
Designed for heavy cutting on 5-axis and multi-axis machines, the DBDB-335-100-810-A26W-A1 provides a continuous rotary-axis torque of 810 N·m (1,150 N·m peak) and integrates an HSK-T63 motorized spindle delivering 80 N·m continuous torque and 37 kW continuous output power for low-speed, high-load machining. The spindle supports up to 12,000 rpm and features high clamping force for secure tool retention.
