Grinding spindle DYFDM-125(080)15/5.5-XVM

hydrostaticISOoil-lubricated

Product overview
Designed for use as a machine-tool headstock rather than a high-speed wheel spindle, the DYFDM-125(080)15/5.5-XVM combines two-way rotation with a 220 V synchronous motor. Rated torque 41.4 N·m and hydrostatic support provide stable workpiece rotation up to 1,500 rpm.
