Internal grinding spindle DGZM-12042/15-DFWQS

motorizedwater-cooledhigh-speed

Overview
A front flange changes how spindle loads are transferred into the machine structure. The DGZM-12042/15-DFWQS combines this flange-mount arrangement with continuous 42,000 rpm operation and 15 kW output for rigid, high-speed internal grinding integration.
