Not all materials can be processed precisely. The requirements of precision machining are very high and very strict. Let’s talk about what requirements do precision hardware processing have on materials?
For metal materials, the hardness is the largest for stainless steel, followed by cast iron, followed by copper and aluminum. The processing of ceramics and plastics belongs to the processing of non-metallic materials.
- first, the hardness of materials is required. For some occasions, the higher the hardness of the material is, the better, but it is limited to the hardness requirements of the machined parts. The processed materials cannot be too hard, and if it is still hard than the machine parts, it cannot be processed.
- secondly, the material is moderate in soft and hard, at least one grade lower than the hardness of the machine piece. At the same time, it also depends on the function of the processed device for the reasonable selection of parts.
Therefore, the most basic one is to pay attention to the density of materials before processing. If the density is too large, it is equivalent to the hardness. If the hardness exceeds the hardness of the machine parts (lathe tool), it cannot be processed, not only damage the parts, but also cause danger, such as the flying and falling of the lathe knife and injuring people. Therefore, generally speaking, for hardware processing, the material material should be lower than the hardness of the machine tool, so that can be processed.
