CRG CNC
CNC Cylindrical Grinding Machine
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 fine 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
