Graphite has excellent self-lubrication, corrosion resistance, wear resistance, low friction coefficient and expansion coefficient, etc. It is often used as a mechanical seal friction pair material. In the machining process of the graphite ring turning, there are frequent chipping, resulting in unsatisfactory product appearance inspection and sealing performance inspection, high product rejection rate and high production cost. This paper analyzes the cause of the edge chipping in the graphite ring turning, and optimizes the tool material, the tool angle, the amount of cutting tool, and the process flow, and solves the chipping problem of turning.

All corners of a mechanical seal graphite ring must not have chipping, and the yield of the seal ring processed by conventional methods is less than 50%. A total of 286 pieces of products were produced using the above-mentioned optimized turning process. Only 32 pieces of turning were found to have a smaller chipping, of which 20 pieces were eliminated in the subsequent face grinding process, and the sealing rings were all tested for airtightness after assembly. ,The product processing pass rate increased to about 96%.
