[0002] PEEK material is a special engineering plastic, with the Chinese name of polyetheretherketone. It has excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. It can be manufactured into various mechanical parts, such as automotive gears, oil screens, shift starter discs, etc. It is also widely used in aerospace, medical equipment and other fields. After the PEEK raw materials are formed, they need to be precisely processed using CNC machine tools to prepare various parts according to specific usage requirements. Various tooling, such as fixtures and cutting tools, are required during the processing of PEEK materials.
