Steel ball machining apparatus capable of eliminating foreign matter

摘要

A steel ball machining apparatus comprises a ball machining mechanism having a pair of machining plates which are adapted to oppose and rotate relative to each other, a steel ball storing vessel for supplying to and receiving from said polishing mechanism steel balls, a steel ball supply path provided between said machining mechanism and said steel ball storing vessel, a steel ball discharge path provided between said machining mechanism and said steel ball storing vessel adapted to discharge said steel balls to said vessel, and a set of parallel bars provided in at least one of said steel supply path and steel ball discharge path so as to eliminate foreign matter.
