What is the material of precision metal parts in industry?
Precision parts, not all materials can be precisely processed, some materials are too hard to exceed the hardness of the machine parts, may be broken, so these materials are not suitable for precision machining, unless it is made of special materials, or laser cutting.
For precision machining materials are divided into two categories, metal and non-metallic materials.
For metal materials, the hardness of stainless steel is the largest, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics and so on belongs to the processing of non-metallic materials.
1. First of all, the requirements of material hardness, for some occasions, the harder the material is, the better, but limited to the hardness requirements of processing parts, processing materials can not be too hard, if harder than the machine parts can not be processed.
2. Secondly, the material is moderate in hardness and softness, at least one grade lower than the hardness of the machine parts. At the same time, it also depends on what the function of the processing device is to do, and the reasonable selection of materials for the machine parts.
In short, there are still some requirements on the material quality of precision parts processing, not all materials are suitable for processing, such as soft or hard materials, the former is not necessary to process, and the latter is unable to process.
Therefore, the most basic one is that before processing, we must pay attention to the density of materials, if the density is too large, equivalent to hardness is also very large, and if the hardness exceeds the hardness of the machine parts (lathe tool), it is unable to process, not only will damage parts, but also cause danger, such as the knife flying out to hurt people. Therefore, generally speaking, for mechanical processing, the material quality should be lower than the hardness of the machine tool, so as to be processed.
