The RS15 is a manual precision tool grinding machine, which enables cost-effective manufacture and machining of polycrystalline diamond and hard metal tools, HSS through to super hard PCD/PKBN as well as other tools, and regrinding of rotational cutting tools and indexable inserts. Thanks to the sophisticated kinematics, convex radii and tangents with constant, variable clearance angles up to 27° or constant profiles can be ground. The constant contact pressure is adapted to the stock removal volume and enables cost-effective grinding of super-hard materials.
