Grinding spindle DYFDM-170(100)30/22-XWS

motorizedhydrostaticISO

Overview
The DYFDM-170 is a hydrostatic headstock spindle designed for machine tool headstocks that require high continuous torque and tightly controlled radial motion. Its built-in synchronous motor provides 22 kW (S1) and 140 N·m continuous torque; the specified front-end radial runout supports precision workpiece rotation.
