Tool grinding machine

In a tool grinding machine, especially for grinding profile cutters;

• a machine frame, workpiece support means mounted on said frame adapted for supporting a cutter with the edge to be ground exposed with the cutter in a predetermined plane, grinding wheel support means on the frame for rotatably supporting a grinding wheel on an axis of rotation for grinding the exposed edge of the cutter, and cooperating elements of template and follower means to control relative movement between the cutter and grinding wheel, said grinding wheel support comprising a first support member pivotal about a first axis on said frame which is transverse to the axis of rotation of the grinding wheel, a second support member mounted on said first support member for movement thereof about a second axis which is parallel to the axis of the grinding wheel and near the peripheral region of the wheel which engages the cutter, said workpiece supporting means comprising at least three superposed relatively moveable carriages the lower one of which is moveable on said frame in one direction and the others of which are moveable thereon in relative directions with the uppermost of the carriages supporting the cutter to be ground, and means supporting said template and follower for adjustment thereof relatively independantly of said workpiece support means and grinding wheel support means.
