ABSTRACT:
An apparatus for grinding/polishing the surface of material samples comprises a horizontal circular wheel which has an upper surface and rotates about its central vertical axis of rotation. On the upper surface is provided mixed abrasive particles centrifugally separated to have the larger particles located near the wheel periphery while the smaller particles near the wheel center. A one-step grinding/polishing operation is thus achieved which is fast, economical, and reproducible. Methods for preparing the apparatus and for the improved grinding/polishing process are also disclosed.
