CNC Cylindrical grinder

CRG CNC

For grinding in the sub-micron range

  • Advanced machine concept, innovative design and cutting edge components from reputable manufacturers are key elements which characterize these CNC cylindrical grinding machines.
  • Exceptional accuracy
  • Standard grinding cycles include dressing of the wheel, as well as grinding cycles of concave and convex surfaces
  • Specially designed fi ne feeds allow grinding results with mirrored surfaces, to an accuracy of 0.1 micron
  • A heavy Meehanite cast frame, heat treated and stress-relieved, provides a solid foundation for the CRG CNC cylindrical grinding machines
  • All guideways are hardened and precision ground to ensure permanent accuracy and wear resistance. Another highlight of this series is the special table design, which uses a hydrostatic system for extremely smooth motion and precision
  • The grinding spindle is made of high quality steel
  • The grinding spindle uses a high-precision hydrostatic spindle bearing that excludes metal-to-metal contact and thus guarantees a true running accuracy of 0.5 microns
  • A wide range of options for your special applications are available on request
