With the development of The Times, precision machining is becoming more and more important in people's life, so what are the requirements of precision machining for materials? Follow me to learn about it.
Precision machining, not what materials can be precision machining, some material hardness is too large, more than the hardness of the machining parts, it may break the parts, so these materials are not suitable for precision machining, unless it is made of special materials, or laser cutting.
Materials for precision machining are divided into two categories, metallic materials and non-metallic materials.
For metal materials, the hardness of stainless steel is the greatest, 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 hardness of the material is required. For some occasions, the higher the hardness of the material is, the better it is.
2. Secondly, the material hardness is moderate, at least a grade lower than the hardness of the parts, but also to see what the role of the processing of the device is to do, reasonable material selection of the parts.
In short, precision machining has some requirements on the material, and not what material is suitable for processing, such as too soft or too hard material, the former is not necessary to process, and the latter is unable to process. Therefore, the most basic one is that we 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 parts (lathe tool), it can not be processed. Therefore, generally speaking, for mechanical processing, the material material should be lower than the hardness of the machine knife, so as to be processed.
