New Date: Nov. 1988

The EWAG RS 12 is a grinding machine for the economic manufacture and re-grinding of polycrystalline diamond, tungsten carbide tools, HSS and other materials as well as pre-grind natural diamond. A major feature of the RS 12 is the capability to measure tools directly on the machine by means of a projector without unclamping.

Refined kinematics allow the grinding of convex radii and tangents with constant or variable relief angles (up to 27") as well as constant profiles. The versatile range of accessories covers practically every requirement and permits grinding operations such as concave and convex radii, spherical shapes, multi-facet grinding on deep hole drill bits, traverse and creep feed grinding, etc.
