ABSTRACT:
An apparatus for abrading a workpiece comprises a first plate assembly having a first surface for supporting a workpiece and a second plate assembly having a second surface for engaging the workpiece to abrade a portion thereof. A displacement shaft is mounted for movement with respect to the upper and lower plate assemblies and has a first end configured to engage the upper plate assembly. A feedback assembly is coupled to the displacement shaft for moving the displacement shaft to substantially maintain a predetermined load exerted on the displacement shaft by the upper plate assembly.
