CNC machine parts processing, not all materials can be precision processed, some materials are too hard, and the hardness of the processed parts may be broken, so these materials are not suitable for CNC machining. Unless it is a machine made of special materials, or laser cutting. So what are the material requirements for CNC parts processing? Let's take a look at it together.
The materials processed by CNC machine parts are divided into two categories, metallic materials and non-metallic materials.
For metallic materials, stainless steel has the highest hardness, followed by cast iron, followed by copper, and finally aluminum.
The processing of ceramics, plastics, etc. is attributed to the processing of non-metallic materials.1. The first is the requirement of material hardness. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined part. The machined material should not be too hard. If it is harder than the machine part, it cannot be machined.
2. Secondly, the material is moderately hard and soft, at least one level lower than the hardness of the machine part. At the same time, it also depends on the purpose of the processed device and the rational selection of the machine part.
In short, CNC machining still has some requirements for materials. Not all materials are suitable for processing, such as materials that are too soft or too hard. The former is not necessary for processing, while the latter cannot be processed.
Therefore, you must pay attention to the density of the material before processing. If the density is too large, the hardness is also large. If the hardness exceeds the hardness of the machine part (lathe tool), it cannot be machined. Not only will it damage the part, It will also pose a danger, such as the turning tool flying out and hurting people. Therefore, in general, for mechanical processing, the material material must be lower than the hardness of the machine knife, so that it can be processed.
