ABSTRACT:
A mechanical device for abrading the surfaces of workpieces is disclosed in which a power driven perforated abrasive coated endless belt comes into intimate parallel contact with a rotatably driven slotted disc platen. The perforated abrasive coated endless belt is oriented so that its noncoated side contacts the slotted disc platen. The periodic alignment of the slots of the revolving disc platen with the perforations of the abrasive coated endless belt allows an operator to continually observe a workpiece while its surface is being abraded.
