Grinding spindle DYFDM-165(100)36/35-XWS

high-powerhydrostaticISO

Overview
This DYFDM-165(100)36/35-XWS hydrostatic headstock spindle is a high-power headstock option featuring a rear-mounted 36 kW asynchronous motor. Equal axial and radial static stiffness of ≥400 N/μm supports large headstock structures where bearing rigidity and power are priorities. Recommended oil cooling improves thermal stability for heavy-duty machining applications.
