Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a polishing method for a dental bur. Background Art

[0002] The polishing process in the production process of dental burs has always been a difficult problem for manufacturers. The existing dental bur polishing mainly adopts the method of adding husks as abrasives in the polishing chamber of the vibration polishing machine for polishing. This polishing process has the following shortcomings: First, the polishing efficiency is too low. It takes 3-5 hours to complete a polishing. In order to complete the polishing of all products, batch equipment needs to be invested. Second, because the product is too small (like the size of an embroidery needle), it is difficult to separate the product and the abrasives (husks) after polishing. If the separation is not thorough each time, the abrasives will cause mixing when used again, and the mixed materials are difficult to distinguish. Third, one device cannot complete the polishing of two or more specifications of products at the same time, otherwise a mixture will be formed. Fourth, the vibration noise is too loud, which pollutes the environment. Therefore, it is necessary to propose a polishing device that can complete the polishing of multiple specifications of products on one device at the same time, with high efficiency, convenient separation, low noise, and can avoid the occurrence of mixing.
