ABSTRACT:
Grinding apparatus for forming noncircular punching tools comprising a grinding wheel having a cylindrical grinding surface, a rotary table with its axis parallel to the grinding wheel axis and carrying orthogonally movable slides such that one slide at a time may be actuated to generate successive flat sides of a punching tool, the table axis being positionable to define a center of rotation for an arcuate face of the punching tool which is generated upon rotation of the table, and a fixture for the grinding wheel dressing tool serving to automatically define the location of the grinding wheel surface relative to the axis of the rotary table.
