GU32x100NC-B

FEATURES

  • Stable and rigid spindle head: The spindle runs on precision bearings, assuring maximum spindle stability. It guarantees outstanding grinding accuracy for external dia., internal dia. (optional) & end face.
  • Precision wheel head: The grinding wheel spindle is precision machined from high-quality alloy steel, normalized, tempered, carburized and sub-zero treated, precision ground and mirror-effect treated.
  • Various grinding applications: One grinder allows straight plunge grinding, shoulder grinding, traverse grinding, end face grinding, taper grinding & internal grinding (optional) functions for different machining purposes.
  • Special hydrostatic bearing: The wheel spindle runs by using a special hydrostatic bearing and is especially ideal for precision grinding work. It features high speed, no friction between metals, no heat generation, deformation-free, extra high accuracy and continual use.
