ABSTRACT:
A microfinishing arm assembly for reducing taper on selected bearing journal surfaces of various workpieces rotated about a longitudinal axis. The microfinishing arm assembly includes a primary finishing arm and a taper correction means for applying a plurality of adjacent independently variable grinding pressures. A primary abrasive means for finishing a journal surface is mountable on the primary finishing arm and adapted for use in cooperation with the taper correction means. A measuring means for gauging the bearing journal surfaces at a plurality of spaced points during rotation is utilized with a processor means for receiving the gauging signals, calculating diameters of the journal surfaces and generating a plurality of output signals corresponding to the diameters of the bearing surfaces at spaced points. A comparator means compares the output signals to determine whether a taper exists on selected journal surfaces and controls the extent to which a taper correction means applies variable grinding pressure to the surfaces to correct the taper.
