초음파 폴리싱 가공에 따른 세라믹재료의 표면거칠기에 관한 연구
A Study on the Surface Roughness of Ceramics According to Ultrasonic Polishing
- 발행 : 2003.03.30
초록
The ultrasonic polishing machine was developed to get super finishing that consist of machine part that can rotate and travel the main shaft with power 1.5kW, ultrasonic generator with frequency 20kHz. By using this machine we were investigated the characteristics of ultrasonic polishing for three different ceramics, and so could be obtained following results. First, we could be obtained the excellent surface for hard-ta-difficult cutting materials. Second, the effect of surface roughness for the feed rate could be shown that the more the feed rate Increases, the more the value of surface roughness increases. Third, owing to the characteristics being progressed brittle fracture in
