Precision processing of material requirements
May 07, 2018

With precision machining, not all materials can be precision-machined. Some materials are too hard and exceed the hardness of the machining parts. They can collapse the parts. Therefore, these materials are not suitable for precision machining unless they are special. Made of material, or laser cut.

Materials for precision machining are divided into two major categories, metallic materials and non-metallic materials.

For metals, hardness is the largest in stainless steel, followed by cast iron, followed by copper, and finally aluminum.

The processing of ceramics and plastics is the processing of non-metallic materials.

1. The first is the requirement for the material hardness. For some applications, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the processing components. The processed material cannot be too hard. If it is harder than the mechanical components, it cannot be processed.

2. Secondly, the material is moderately soft and hard, at least one grade lower than the hardness of the parts. At the same time, it depends on the function of the device being processed and the proper selection of the parts.

In short, there are still some requirements for precision machining on the material. Not all materials are suitable for processing. For example, the material is too soft or too hard. The former is not necessary for processing, while the latter is impossible to process.

Therefore, the most basic one is that before processing, we must pay attention to the density of the material. If the density is too high, it is equivalent to a large hardness. If the hardness exceeds the hardness of the machine (lathe turning tool), it cannot be processed. It can only damage the parts and can also cause dangers, such as the tool blade flies out and hurts people. Therefore, in general, for mechanical processing, the material material is lower than the hardness of the machine knife so that it can be processed.
