What kind of material is suitable for precision machining?
In China's precision machining, which fields are precision machining applied to? Precision machining has high precision and high processing cost. It is mainly used in civil and military fields such as national defense, medical equipment, aerospace, and electronic production. With the continuous development of the optimization and upgrading of China's industrial structure, the demand for mechanical parts processing is also increasing. Therefore, it is highly valued; therefore, a large amount of manpower, material resources and financial resources have been invested in this area to cultivate talents in the development of precision mechanical parts processing in our country.
Regarding precision machining, not all materials are available. Some materials are too hard to exceed the hardness of the machined parts, and the machine parts may collapse. Therefore, these materials are not suitable for precision machining unless they are special materials. Manufactured parts, or laser cutting.
Precision machining materials can be divided into two types: metallic materials and non-metallic materials. For metal materials, the hardness is greater for stainless steel, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials.
1: First of all, it is the requirement of material hardness. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined parts. The machined material should not be too hard. If it is harder than the machine part, it cannot be processed.
Two: Secondly, the material is moderately hard and soft, at least one grade lower than the hardness of the machine part. At the same time, it also depends on the purpose of the machined device and the rational selection of the machine part. In short, 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 is not necessary for processing, while the latter cannot be processed.
