Abstract: An arrangement for the grinding and cutting of rotary profile cutters having, in combination mounted on a base, a first reciprocable table on which is mounted a rotatable platen. A rotatable workpiece carrier assembly is fixed to the platen and these have mutually perpendicular axes of rotation. The carrier holds a collet for the milling cutter blank and a programmable indexer for the angular positioning of the blank in successive position. A second table can reciprocate perpendicular to the first and acts as a support for a block carrying a grinding wheel spindle head. The block is capable of oscillation to either side of a vertical position on an axis parallel to the axis of reciprocation of the second table and the grind wheel spindle head can slide perpendicular to the axis of rotation of the block. A rotatable grinding wheel carried by the spindle head can have its plane of gyration moved to either side of the axis of rotation of the block. Means are provided for effecting movement of the tables as are programmable driving mechanisms for controlling the movements.
