It is necessary to select appropriate tools, cutting parameters and cooling methods based on the material properties. For metal materials, special attention should be paid to tool wear and thermal deformation. For composite materials, delamination and burrs should be avoided. For plastic materials, thermal deformation and dimensional accuracy should be controlled. By optimizing the processing technology, the processing quality and production efficiency of parts can be significantly improved.<\/p>","protected":false},"excerpt":{"rendered":"<p>Die CNC-Bearbeitungsleistung von Automobilteilen aus unterschiedlichen Materialien variiert aufgrund der physikalischen und chemischen Eigenschaften der Materialien selbst.
