What are the specific requirements for materials in the processing of precision mechanical parts

For precision mechanical parts, no material can be processed. If the hardness of the material processed by precision mechanical parts exceeds the hardness of the lathe tool, the lathe tool will be damaged, so these materials are not suitable for precision machining. So what are the specific requirements for materials for the processing of precision mechanical parts? 1. The hardness of the material. In some cases, the higher the hardness, the better the material, but for the processing of precision mechanical parts, the material can only be limited to lathes. The hardness of the knife, if the material is harder than the lathe tool, it cannot be processed. 2. The material should be moderately hard and soft. The machining material of precision mechanical parts should be at least lower than the hardness of the lathe tool. At the same time, it is necessary to understand the purpose of precision mechanical parts, so as to choose a suitable lathe tool for processing. 3. Pay attention to the density of the material. Before processing the precision mechanical parts, you must pay attention to the density of the material. If the density is too high, the hardness is also very large, but the hardness exceeds the hardness of the lathe tool, and the processing cannot be performed. The turning tool of the lathe that will be damaged will also cause the turning tool to break off and other dangers. Precision mechanical parts processing has certain requirements for material quality, and not all materials are suitable. If the material is too soft, there is no need for precision machining. If the material is too hard, the lathe tool cannot be processed.
