Drehspindel
Drehspindel (German for "rotating spindle") denotes a rotating shaft assembly in machine tools and other machinery that supports and drives a workpiece or cutting tool. It is a central component in lathes, milling machines, grinders and CNC equipment, providing precise rotational motion with controlled speed, torque and axial/radial stiffness.
Typical construction includes the spindle shaft, bearings (roller, ball, or hydrostatic), a spindle nose or tool-holder
Drehspindeln vary by drive type (belt-driven, gear-driven, direct-drive/motor spindle), size, speed range and rigidity. Motor spindles
Applications span metalworking, woodworking, stone machining, and precision grinding. Performance metrics include maximum RPM, torque, power,
Maintenance and monitoring focus on bearing condition, lubrication, balance, sealing and temperature/vibration trends. Regular inspection and
