The surface quality and machining accuracy of precision parts machinists are closely related. Suppose that the surface of a part is very rough, can its dimensional accuracy and shape and position accuracy be high?
Control the quality of raw materials: high quality raw materials are the prerequisite for producing high-quality products. Gears are made of 40Cr and 45 steel. No matter through which way, raw materials must undergo strict chemical composition inspection, grain size determination and purity evaluation after arriving at the factory. Its purpose is to adjust the heat treatment deformation in time and improve the quality of tooth profile machining.
The surface quality of precision parts machinists is often required by the use of parts. For example, many parts require high surface hardness, such as molded parts of molds. The surface quality is to meet the functional requirements of parts. There are also: the surface quality of precision parts affects the use of parts, and the parts with surface defects affect the use performance of parts.
