• We have developed the ultrasonic polishing machine that consist of machine part that can rotate and travel the main shaft with power 1.5kW, ultrasonic generator with frequency 20kHz to get super polishing of work-piece surface. Using this system we investigated the characteristics of ultrasonic polishing for three different ceramics and obtained following results. First, excellent surface for hard-to-difficult cutting materials could be obtained. Second, it was shown that the value of surface roughness increase, as the feed rate becomes greater. Third, owing to the characteristics being progressed brittle fracture in Al_2O_3 polishing with this system, the value of surface roughness is larger than other ceramics. Forth, because the ultrasonic polishing can be smoother than the existing grinding in discharging the chips, it could be possible to improve the surface roughness about up to 15%.
