Kaast CRG

For grinding in the sub-micron range Highaccuracy 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 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
