Tool profile grinding machine, with mechanical adjustment of the grinding wheel and positioning of the tool interrelated

A profiled tool shaping machine, comprising:

• a machine frame;
• a working head having a grinding disc rotatably mounted thereto about a disc axis and in a disc plane, said working head pivotably mounted to said frame about a vertical axis for horizontal pivoting of said disc and disc plane;
• a work table slidably mounted to said frame for motion in at least two horizontal orthogonal directions with respect to said frame and said disc;
• a work piece holder mounted to said table for holding a work piece adjacent said disc, which work piece is to be shaped into a profiled tool;
• a dummy template having a profile corresponding to a profile of a tool to be shaped, fixed to said table;
• a feeler fixable to said frame and engaging said template for causing motion of said table in one direction when said template with said table is moved past said feeler in another direction;
• a first lever connected to said working head for pivoting said working head with said disc about said vertical axis;
• a compensator member connected to said frame and having a plurality of positions defined thereon;
• a first linkage connected between said first lever and said compensator member at one of said plurality of positions;
• and
• a second linkage connected between said table and said compensator member at one of said plurality of positions so that, movement of said first lever causes simultaneous movement of said table in said other direction and rotation of said working head with said disc about said vertical axis by selected amount proportional to the movement of said table in said other direction.
