Analysis of the requirements for the processing of precision mechanical parts
Release date: 2019-04-16 14:57:13 Visits: 853
Before processing precision mechanical parts, we must pay attention to the density of the material. If the density is too large, it is equivalent to a large hardness. If the hardness exceeds the hardness of the lathe turning tool, it cannot be processed, not only will damage the parts, but also cause Danger, such as a car knife crashing out and hurting people. So, what are the requirements for the processing of precision mechanical parts?
What are the requirements for the processing of precision mechanical parts?
For precision machining materials are divided into two categories, metal materials and non-metal materials. For metal materials, the hardness is the largest for stainless steel, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. is a processing of non-metallic materials.
Stainless steel for precision mechanical parts machining
1. First of all, the material hardness requirements. For some occasions, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the machined parts. The processed material should not be too hard. If it is harder than the machine parts, it cannot be processed.
2. Secondly, the material is moderately soft and hard, at least one grade lower than the hardness of the machine. At the same time, it depends on what the function of the processed device is, and the material is reasonably selected.
In short, precision machining has some requirements on materials. Not all materials are suitable for processing. For example, materials that are too soft or too hard, the former is not necessary for processing, while the latter cannot be processed.
Therefore, in general, for mechanical processing, the material of the material is lower than the hardness of the machine tool so that it can be processed. Not all materials can be precision machined. Some materials are too hard. If the hardness of the machine is exceeded, the parts may collapse. Therefore, these materials are not suitable for precision machining unless they are made of special materials. Mechanical parts, or laser cutting.
