For a long time, the deburring of fluoropolymers, Teflon, and PTFE has been the most difficult plastic material for ultrasonic deburring. However, PPS mixed with PTFE, machining burrs of fluoropolymers, and processing burrs of PTFE are now sufficiently stable deburring targets for ultrasonic deburring. The same is true for processing burrs on PEEK. The practical…続きを読む
