Precision machining requirements for certificates

Not all raw materials can be used for precision machining. Some raw materials are too hard, which may exceed the hardness of the machined parts, which may break the machine parts. Therefore, these raw materials are not suitable for precision machining, unless they are made of special materials. Into the machine parts, or laser cutting.

The raw materials for precision machining by precision machining manufacturers are divided into two categories, metal raw materials and non-metal raw materials. For metal raw materials, the hardness is greater than stainless steel, followed by cast iron, followed by copper, and then aluminum. The processing of ceramics, plastics, etc. is attributed to the processing of non-metallic raw materials.

Precision machining mainly puts forward requirements for the hardness of the certificate material. For some places, the higher the hardness of the raw material, the better, but it is limited to the hardness requirements of the machined parts. The processed raw materials cannot or may be too hard. It is assumed to be more rigid than the machine parts. It is hard to process. The raw materials are moderately soft and hard, at least one level lower than the hardness of the machine parts. At the same time, it depends on the benefits of the processed parts and the reasonable selection of the machine parts.

Precision machining may require little or no certificates. Not all raw materials are suitable for processing. It is like raw materials that are too soft or too hard. The former does not require processing, while the latter cannot be processed. Therefore, we must pay attention to the density of raw materials before processing.

Assuming that the density is too high, it is equivalent to the hardness. If the hardness exceeds the hardness of the machine part (lathe tool), it cannot be processed. Not only will it damage the part, but it will also pose a danger, like a turning tool flying out of injury. People wait. Therefore, generally speaking, for mechanical processing, the material material is lower than the hardness of the machine knife, so the ability to be processed.
