Objective To develop the dental ultrasonic polishing instrument used in polishing chromium cobalt castings. Methods According to the principle of ultrasonic vibrating and polishing, the ultrasonic polishing device was made and debugged with ultrasonic generator, ultrasonic vibration system. 40 finished specimens of chromium cobalt alloys were polished by the device with alumina abrasives, the surface roughness of the specimens were measured. Results The ultrasonic polishing instrument which could reduce significantly the surface roughness of the specimens was made.Conclusion The dental ultrasonic polishing instrument was effective on the polishing of Chromium Cobalt castings.
