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 the collapse of machine parts. Therefore, these materials are not suitable for precision machining unless they are machine parts made of special materials or laser cutting.
The requirements are specific to every work, because it will directly affect the quality of products produced. Therefore, in order to ensure the quality of products, we should not only have requirements for equipment, but also for operators and some processed materials. These all need to have certain standards. Only if these meet the standards, can the products produced be our ideal appearance. Let's know what the material requirements for precision parts processing are?
The processed materials are divided into two categories, metallic materials and non-metallic materials; For metal materials, stainless steel has the highest hardness, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics and plastics belongs to the processing of non-metallic materials. For the hardness requirements of materials, in some cases, the higher the hardness of materials, the better, but it is inferior to the hardness requirements of machined parts. The processing materials should not be too hard; If it is harder than mechanical parts, it cannot be processed; The material must be moderate in hardness and softness.
At least one grade lower than the hardness of the machine. At the same time, it also depends on the function of the processed equipment and the reasonable choice of the machine. In the process of CNC parts processing and manufacturing, due to the different production requirements and conditions of each part, the manufacturing process plan is also different. When different process schemes are used to produce the same parts, their production efficiency and economic benefits are also different.
