A profile grinding apparatus comprising a stationary frame, a template support table and a workpiece support table. The workpiece support table is mounted at a fixed position on the frame. A pantograph and parallelogram assembly is mounted on the frame for horizontal movement in response to the movement of guiding means. A first movable support is mounted on the frame coupled to the pantograph and parallelogram for following movement of the guide means. A second movable support is mounted on the frame below the first movable support means and coupled thereto for movement therewith. A vertically reciprocable grinding assembly is carried between the first and second movable supports to grind a contour on the workpiece mounted on the workpiece table. A shadowgraph is located on the frame at a fixed position adjacent the workpiece table for projecting an image of the profile of the workpiece. The grinding means is also arranged for reciprocation at an acute angle to the vertical axis. The template table includes means for coupling the guiding means of the pantograph thereto to enable the pantograph to move the grinding means in response to the movement of the template holding table. The first and second supports which carry the grinding means are mounted on the fixed frame and coupled to the pantograph by a movable support assembly including a pair of vertical rods and associated brackets.
