Paper Abstract

An exploratory study was conducted to determine the feasibility of polishing CVD diamond films with abrasive-liquidjets. A nozzle system that produces a high-velocity radial flow (between nozzle and workpiece) with zero or near-zero impact angles was used for polishing tests. The abrasive particles are acted upon by hydrodynamic forces to effect polishing. The relatively high particle flow rates (10 g/s) and velocities (over 150 m/s) result in relatively high polishing rates. The inertial effect of the abrasive particles appears to contribute significantly to the material removal. A diamond film was polished from 3 to 1.3 microns at a rate of 2.7 micron/s/mm2 using 600-mesh SiC abrasives.
