What are the requirements of material selection for precision machining

Release time：2020-11-10Author：admin

In all kinds of processing industries, precision machining requires high precision and cost, and the products are mostly used for national defense equipment, medical equipment, aerospace equipment and high-end electronic equipment. With the continuous optimization and development of China's industrial industry, the requirements for precision machining parts are also increasing. However, due to the nature of processing, the requirements for precision machining parts are increasing All materials can be processed, so which materials are suitable for precision machining.
As for precision machining, not all materials can be used. If the hardness of some materials is too high and exceeds the hardness of machine parts, the parts may be broken. Therefore, these materials are not suitable for precision machining, unless they are parts made of special materials or laser cutting.

Precision machining materials can be divided into two types: metal materials and non-metallic materials.

For metal materials, the hardness of stainless steel is greater, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics and plastics belongs to the processing of non-metallic materials.
1： The first is the requirement for the hardness of materials. For some occasions, the higher the hardness of materials, the better. It is only limited to the hardness requirements of machine parts. The processed materials cannot be too hard. If they are harder than the parts, they cannot be processed.
2： Secondly, the material should be soft and hard, which should be at least one grade lower than the hardness of the machine parts. At the same time, it also depends on the function of the processed components, so as to reasonably select materials for the parts. In short, there are still some requirements for materials in precision machining. Not all materials are suitable for processing. For example, materials that are too soft or too hard are not necessary to be processed, while the latter cannot be processed.
