Positive connection between cutter plate and backing plate has tooth profile on both radial side edges of cutter plate

摘要

The positive connection is made by means of tooth profiles on both the side edges of the cutter plate (1) and corresponding tooth profiles on the edges of a recess in the surface of the backing plate. The cutter plate is laid in the position determined by the tooth profiles. The flank surfaces of the profiles diverge outwards at a small angle.
