Milling spindle DGZX-15018/20-BBT

motorizedBT 40air-cooled

Product summary
The DGZX-15018/20 is a compact dual-winding spindle integrating two winding ranges within a Φ150 mm BBT40 platform. It delivers a torque-oriented low-winding mode and a high-speed winding mode, enabling machine builders to combine high torque and efficient milling without the larger footprint of the 190 mm variant.
