What are the material requirements for cnc part machining?

Cnc parts machining, not all materials can be precision machined. Some materials are too hard to exceed the hardness of machined parts, which can damage parts. Therefore, these materials are not suitable for cnc parts machining unless they are parts made of special materials or laser cuts.

There are two types of materials for cnc parts, metal materials and non-metal materials.

For metal materials, stainless steel has a high hardness, followed by cast iron, copper and aluminum.

machining of ceramics, plastics, etc. It belongs to the machining of non-metallic materials.

1, the first is the material hardness requirements, for some occasions, the higher the hardness of the material, the better, only limited to the hardness requirements of cnc parts machining, machining materials can not be too hard, if only can not be processed harder than the parts.

  1. Secondly, the material is moderately soft and hard, at least lower than the hardness of the machine parts. At the same time, it also depends on the function of the machine parts and the reasonable choice of the material of the machine parts.

In short, cnc parts still need some materials, not all materials are suitable for machining, such as too soft or too hard materials, the former is not necessary for machining, while the latter can not be processed.

Therefore, we need to pay attention to the density of materials before machining. If the density is too high, it is equivalent to a large hardness. If the hardness exceeds the hardness of the machine part (lathe tool), it cannot be processed. Not only will it damage the parts, but it will also cause dangers, such as a car crash and go out and hurt people. Therefore, in general, for mechanical machining, the material of the material is lower than the hardness of the machine tool so that it can be processed.
