CNC Cylindrical grinder

CRG CNC

For grinding in the sub-micron range








  • Advanced machine concept, innovative design andcutting-edge components from reputable manufacturersare key elements which characterize these CNC cylindricalgrinding machines
  • Exceptional accuracy
  • Standard grinding cycles include dressing of the wheel, aswell as grinding cycles of concave and convex surfaces
  • Specially designed fine feeds allow grinding results withmirrored surfaces, to an accuracy of 0.1 micron
  • A heavy Meehanite cast frame, heat treated and stressrelieved,provides a solid foundation for the CRG CNCcylindrical grinding machines
  • All guideways are hardened and precision ground toensure permanent accuracy and wear resistance. Anotherhighlight of this series is the special table design, whichuses a hydrostatic system for extremely smooth motionand precision
  • The grinding spindle is made of high quality steel
  • The grinding spindle uses a high-precision hydrostaticspindle bearing that excludes metal-to-metal contact andthus guarantees a true running accuracy of 0.5 microns
  • A wide range of options for your special applications areavailable on request
