Finishing spindle DGZX-19018/20-BBT

millingmotorizedBT 40

Overview
The DGZX-19018/20-BBT dual-winding milling spindle features a Φ190 mm housing engineered to deliver strong low-speed torque for heavy roughing and a high-speed winding for finishing up to 18,000 rpm. Designed for BBT40 machining centers, it provides flexible performance across roughing and finishing operations and supports common industrial cooling and monitoring options.
