Grinding Machine Model


Kaast CRG
2-Axis CNC O.D. Cylindrical Grinder with Optional Internal Grinding Unit

PRODUCT

For grinding in the sub-micron range

High 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 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
