CNC machining of high-precision parts is not suitable for precision machining of all materials. Some materials are too hard, exceeding the hardness of the processed parts, which may cause machine parts to collapse. Therefore, these materials are not suitable for precision machining unless they are machine parts made of special materials or laser cutting.

Requirements are specific to every job, as they directly affect the quality of the products produced. Therefore, in order to ensure product quality, we not only need to have requirements for equipment, but also for operators and some processed materials. These all require certain standards. Only by meeting these standards can the products produced be our ideal appearance. So let's understand the material requirements for precision parts processing?

The processed materials are divided into two categories: metallic materials and non-metallic materials; For metallic materials, stainless steel has the highest hardness, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. For material hardness requirements, in some cases, the higher the hardness of the material, the better, but it is lower than the hardness requirements of the processed parts. Processing materials should not be too hard; If it is harder than a mechanical component, it cannot be processed; The material needs to be moderately soft and hard.

At least one level lower than the hardness of the machine, and at the same time, it also depends on the function of the processed equipment and the reasonable selection of the machine. In the manufacturing process of CNC parts, due to the different production requirements and conditions of each part, the manufacturing process plan is also different. When using different process plans to produce the same parts, their production efficiency and economic benefits also differ.
