Do you know what the material requirements for precision parts processing are?
For precision parts processing, not all materials can be precisely processed. Some materials are too hard, which may break the parts if they exceed the hardness of the processing parts. Therefore, these materials are not suitable for precision processing unless they are made of special materials or laser cutting.
For metal materials, the hardness of stainless steel is the largest, followed by cast iron, followed by copper, and finally aluminum. The data of precision machining can be divided into two categories: metal data and non-metal data. The processing of ceramics and plastics belongs to the processing of non-metallic materials.
1. First of all, the requirements for material hardness. For some places, the higher the hardness, the better. It is only limited to the hardness requirements of processing parts. The processing data cannot be too hard. If it is harder than the parts, it cannot be processed
2. Secondly, the material is moderate in hardness and softness, at least one grade lower than the hardness of the parts. At the same time, it depends on the role of the processed components and the reasonable selection of materials for the parts.
In a word, there are still some requirements for precision parts processing. Not all materials are suitable for processing. For example, for too soft or too hard materials, the former is not necessary for processing, while the latter cannot.
Therefore, the most basic thing is to pay attention to the density of the material before machining. If the density is too large, it is equivalent to a large hardness. If the hardness exceeds the hardness of the machine part (lathe tool), it will not only damage the parts, but also cause danger, such as the sharp fall of the lathe tool. Generally speaking, for mechanical processing, the material should be lower than the hardness of the machine tool, so that it can be processed.
