Abstract:
A specular polishing apparatus for work edges, characterized in that the apparatus comprises:a table rotatable around its central axis;a plurality of polishing drums for simultaneous specular polishing of a circumferential edge of a work at a number of points, said polishing drums being disposed around the central axis of said rotatable table, each said polishing drum being configured to rotate around its own axis, said polishing drums having gaps between them that are narrower than the diameter of the work;a plurality of work-holding means disposed around said polishing drums on said rotatable table at a specified interval so as to hold and rotate a disc-shaped work having a chamfered front-plane edge and a chamfered rear-plain edge while contacting one of said chamfered edges of the work simultaneously with a number of polishing drums;said rotatable table having a drive means for intermittently rotating said rotatable table so that each work-holding means sequentially moves between a handling position, a front-plane edge processing position, and a rear-plane edge processing position;a handling means for unloading a processed work from the work-holding means at said handling position and supplying an unprocessed work to said work holding position at said handling position; anda work-inverting means for inverting a work after its front-plane edge has been polished.
