What are the requirements for the material quality of precision parts processing? In the process of precision parts processing and manufacturing, due to the different production requirements and conditions of various parts, the manufacturing process plans are also different. When the same parts are produced by different process schemes, their production efficiency and economic benefits are also different.

Under the premise of ensuring the quality of the parts, the process of formulating a reasonable and feasible process plan with good comprehensive technical and economic benefits is called the process design of the parts. In addition, there are certain requirements for the selection and quality of materials.

Not all materials can be precision machined, some materials are too hard, more than the hardness of the machined part, it is possible to collapse the part, so these materials are not suitable for precision machining, unless it is a part made of special materials, or laser cutting.

The materials used are divided into two categories: metal materials and non-metal materials. For metal materials, the highest hardness is stainless steel, followed by cast iron; then copper, and finally aluminum; and the processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials .

Regarding the hardness requirements of the material, in some cases, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined parts; the material to be machined cannot be too hard. The material is moderately soft and hard, at least one grade lower than the hardness of the part. At the same time, it also depends on the function of the processing equipment and the reasonable selection of the part material.

Precision machining still has some requirements for materials, not all materials are suitable for processing, such as materials that are too soft or too hard, the former does not need to be processed, and the latter cannot be processed.
