What are the material requirements for machining precision parts?
It is strictly forbidden to select materials for hardware parts processing, and high-quality materials can
Ensure that the processing equipment will not be excessively damaged, and the finished product rate of the processed parts
High precision and other aspects will have a good effect.

High precision and other aspects will have a good effect. In case of purchased materials
The material is not good enough. For example, the hardness of hard materials is too high, which exceeds the hardness of machined parts
The processing equipment may be damaged and the workpiece may be affected
Materials are not suitable for precision machining, except for parts made of special materials or
Light cutting. So, what are the requirements for the use of materials when processing hardware parts?

The precision machining materials in the processing of hardware parts are divided into two categories: metal materials and non metal materials
Metallic materials.
For metal materials, the hardness is stainless steel first, followed by cast iron, followed by
Copper, then aluminum. The processing of ceramics and plastics belongs to the addition of non-metallic materials
Work; The main requirements for hardware parts processing are as follows.
1. The first is the requirement for material hardness. For some occasions, the hardness of the material is higher
The higher the better, it is only limited to the hardness requirements of processing parts, and the processed materials cannot be too
It is hard. If it is harder than the machine parts, it cannot be processed.
2. Secondly, the material is moderate in hardness and softness, at least one grade lower than the hardness of parts
It also depends on the function of the processed components and the reasonable selection of materials for the components.
In a word, the precision machining in the processing of hardware parts has certain requirements on the materials, and
Not all materials are suitable for processing, such as too soft or too hard materials,
The former is unnecessary for processing, while the latter cannot be processed.
Therefore, we must pay attention to the density of the material before processing. If the density is too large
The hardness is also very high, and if the hardness exceeds the hardness of the machine part (lathe tool), it is zero
It can not only damage the parts, but also cause dangers, such as the flying out of the turning tool
Hurt people, etc. Therefore, generally speaking, for mechanical processing, the material quality
It should be lower than the hardness of the machine tool, so that it can be processed.
