Automotive precision parts processing is divided into two categories: metallic materials and non-metallic materials. For metal materials, the hardness is greater for stainless steel, followed by pig iron, followed by copper, followed by aluminum. The processing of porcelain, plastic, etc. belongs to the processing of non-metallic materials; the key provisions of hardware parts processing are as follows.
1. First of all, the provisions of material hardness. For some places, the greater the hardness of the material, the better, but limited to the hardness provisions of the processed parts. If the processing material can not be too hard, it can not be processed.
2. Secondly, the material hardness is moderate, at least lower than the hardness of the part, but also depends on what the role of the processing equipment is, and a reasonable choice of parts.
In short, hardware parts processing in the precision machining of the material has certain requirements, not suitable for any material, such as too soft or too hard material, the former does not need to be processed, the latter can not be processed.
Therefore, precision CNC machining factory home before processing must pay attention to the density of the material, if the density is too large, which is equivalent to the hardness is also large, if the hardness exceeds the hardness of the parts (lathe tool), it can not be processed, not only will damage the parts, but also lead to risks, such as knife flying out of harm. Therefore, in general, for mechanical-type processing, the material material to be less than the hardness of the machine tool, how can be processed.
