Grinding spindle DGZM-15024/22-DFWS

high-powermotorizedwater-cooled

Overview
At the larger end of internal grinding spindles, the DGZM-15024/22-DFWS prioritizes power and torque over maximum speed. The 150 mm body delivers 22 kW and 17.7 N·m at rated conditions for heavy grinding passes. Water cooling and ceramic ball bearings enable sustained operation in demanding internal-grinding applications.
