ABSTRACT:
A machine and procedures for finish grinding of indexable cutting tool inserts made of tungsten carbide and other similar materials which includes a fixture for positioning inserts individually in a work holder and moving the work holder to a position in which the work is adjacent a rotating grinding wheel. Control device moves the insert into contact with the wheel with a gauge limiting the contact and also providing for rapidly turning an insert from one flat edge to another flat edge to avoid overgrinding of the corners and to speed up the ultimate grinding of all of the flat sides of a polygonal insert.
