ABSTRACT:
A process and apparatus for the finish grinding of cutting blades of a cutting tool head of a granulating device for thermoplastic material in which a grinding wheel is supported for rotation about a vertical axis with a grinding surface of the grinding wheel facing upwardly and the cutting blades of the cutting tool head rest on the grinding surface of the cutting tool head under the weight of the grinding wheel. The cutting tool head is free for vertical movement and is precisely aligned with the axis of rotation of the grinding wheel. The grinding wheel is driven by a motor around a vertical axis to grind the cutting surfaces of the cutting blades and produce precision ground surfaces on the blades which are aligned in a common plane.
