With the development of the times, precision machining has become more and more important in people's lives. So what are the requirements for materials for precision machining? Let's go and find out with the editor.
Precision machining, not all materials can be precision machining, some materials are too hard, exceeding the hardness of the machined parts, the machine parts may collapse, so these materials are not suitable for precision machining. Unless it is a machine made of special materials, or laser cutting.
The materials for precision machining 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, plastics, etc. belongs to the processing of non-metallic materials.
1. The first is the requirement for the hardness of the material. For some occasions, the higher the hardness, the better. It is only 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 processing.
2. Secondly, the material is moderate in hardness and hardness, at least one grade lower than the hardness of the machine. At the same time, it also depends on the purpose of the machined device and the rational selection of the machine.
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. Therefore, the most basic one is that you must pay attention to the density of the material before processing. If the density is too large, the hardness is also large. If the hardness exceeds the hardness of the machine (lathe tool), it cannot be processed. Only the parts will be damaged, but it will also cause danger, such as the turning tool flying out and hurting people. Therefore, in general, for mechanical processing, the material material must be lower than the hardness of the machine knife, so that it can be processed.
The above is the editor's understanding of the material requirements of precision machining. If you have any questions, please consult this site, website address: http://www.dghongye.com
