Centrifugal barrel polishing machine and centrifugal barrel polishing method |
摘要 |
A centrifugal barrel polishing machine includes a barrel which is configured to perform planetary rotation and into which workpieces and ceramic polishing media are put, thereby polishing the workpieces by the polishing media. A relative centrifugal acceleration F during the planetary rotation of the barrel is set in a range of 2.1(n/N)+29.5≦F≦6.1(n/N)+40.7 where N designates a revolution speed of the barrel, n designates a rotation speed of the barrel, R designates a radius of an orbital path drawn by a rotation center of the barrel, n/N designates a rotation/revolution ratio of the barrel, and F=4π2N2R/g designates a relative centrifugal acceleration which is a ratio of a centrifugal acceleration on the orbital path during the planetary rotation of the barrel to gravity acceleration g. |
