What kind of material for precision parts processing

The material for precision parts processing is made of special materials. It is not possible to process parts with high hardness, otherwise the machine parts will be broken. Therefore, we must know that not all materials are suitable for precision machining. The processed materials can be divided into metallic materials and non-metallic materials.

The requirements for material hardness of precision parts processing. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the processing machine. The material cannot be too hard. If it is harder than the machine, it will not be processed. .

In general, the hardness of stainless steel is large, followed by cast iron, followed by copper, and then aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials.

The processing materials of precision parts are moderately soft and hard, at least one grade lower than the hardness of the machine parts, and at the same time, it depends on what the processing device is used for, and the material selection of the machine parts is reasonable.

One of the basics of precision parts processing is that you must pay attention to the density of the material before processing. If the density is too high, it is equivalent to the hardness, and if the hardness exceeds the hardness of the machine, it will not be processed, and it will not only damage the part It can also cause dangers, such as flying tools falling and hurting people. Therefore, in general, for mechanical processing, the material must be lower than the hardness of the machine knife so that it can be processed.
