We all know that the smaller the parts are, the higher the requirement for machining accuracy is, and this kind of high-precision parts processing we also call it the precision parts processing, because of its very high precision requirements, so the performance of the processing machine and Accuracy requirements are correspondingly very high, and the material can not use too high strength hardness of the material, this type of material will increase the difficulty of processing, if the hardness of the processing machine is exceeded, and may even damage the machine. So what are the requirements for the processing of precision parts? The following Xiao Bian will introduce it to everyone one by one.
There are many kinds of materials in common processing, but we can classify them as metal and nonmetal. The highest hardness of metal is stainless steel, followed by iron, copper again, and finally aluminum. Among the non-metallic materials, ceramics and plastics are particularly representative.
1. First of all, as far as the hardness of the material is concerned, in some applications, of course, the higher the hardness, the better. However, because the hardness of the processing machine has a certain limit, the material to be processed must not be too hard, at least not. If it is higher than the hardness of the machine tool, if it is higher than the hardness of the machine tool, it must be impossible to machine.
2. Secondly, not only should the hardness and hardness of the material be moderate, but also it should be at least one grade lower than the hardness of the components, and the effect of the processing device must be analyzed before a reasonable selection of the components. Only in this way can we guarantee that the products produced are the most compliant and most economical.
All in all, the selection of materials used in the processing of precision parts must have certain requirements. Not all materials are suitable for processing. Materials that are too soft or too hard are not feasible. Therefore, in general, materials must be carefully determined before processing. Pay attention to the hardness of the material. The material with ultra-high hardness will not only damage the parts, but also may cause accidents such as the turning of a tool.
