Grinding cutter heads for granulators - has cutter head resting under its own wt. on horizontally rotating grinding plate covered with grinding cpd. to grind all blades simultaneously

摘要

A cutting head for a granulator for thermoplastics is ground by placing it on a rotating grinding plate covered with grinding compound. The grinding plate is rotated about a vertical axis at the required speed and the cutting head rests on it under its own weight so that all the blades are ground simultaneously. USE/ADVANTAGE - Used for grinding and sharpening cutting heads for granulators. The cutters are ground to be exactly flat without requiring close adjustments to fine tolerances.
