According to the search results, the main processing surfaces of the valve cover are the hole and the outer cylindrical surface. The processing of the outer cylindrical surface can be selected by turning or grinding according to the precision requirements. In addition, the fixture design is also an important link in the valve cover processing. The fixture can ensure the stability and precision of the parts during the processing and improve the production efficiency. When designing the fixture, it is necessary to consider the processing requirements of the parts and the characteristics of the machine tool, and design a fixture that can both ensure the processing accuracy and improve the production efficiency.
