Although the selection of materials for hardware parts processing is not very rigorous, it is also not sloppy. Good materials can not only ensure that the equipment will not be damaged too much, but also have a good value in all aspects such as high yield and precision of parts. If the material purchased is not good, if it is a hard material, the hardness is too high, which exceeds the hardness of the machined parts, and the mechanical equipment may collapse, and the workpiece will also be affected. Therefore, these materials are not suitable for precision machining, unless they are made of special materials or laser cutting. Then, what are the requirements for material use in hardware parts processing?
Precision machining materials in hardware parts processing are divided into two categories, metal materials and non-metallic materials. For metal materials, the hardness of stainless steel is the largest, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics and plastics belongs to the processing of non-metallic materials; The main requirements for hardware parts processing are as follows.
1. The first is the requirement for the hardness of materials. For some occasions, the higher the hardness of materials, the better. It is only limited to the hardness requirements of processing machine parts. The processed materials cannot be too hard. If they are harder than machine parts, they cannot be processed.
2. Secondly, the material is moderately soft and hard, which is at least one grade lower than the hardness of the machine parts. At the same time, it also depends on the role of the processed devices and the reasonable material selection of the machine parts.
In short, the precision processing of hardware parts has certain requirements for materials, and not all materials are suitable for processing, such as too soft or too hard materials. The former is not necessary for processing, while the latter is unable to process.
