What are the requirements for raw materials in machining?

In precision machining, the choice of materials is very important. The choice of raw materials is the first step that affects precision machining of workpieces. Choosing suitable materials is the first step in precision machining. So what are the requirements when choosing materials?

1. Requirements for material hardness

In some cases, the higher the hardness, the better the material, but for precision mechanical parts processing, the material can only be limited to the hardness of the lathe tool. If the material is harder than the lathe tool, it cannot be processed. .

2. The material should be moderately soft and hard

The machining materials for precision mechanical parts should be at least lower in hardness than lathe tools. At the same time, it is necessary to understand the purpose of precision mechanical parts, so as to choose a suitable lathe tool for processing.

3. Pay attention to the density of the material

Be sure to pay attention to the density of the material before processing precision mechanical parts. If the density is too high, the hardness is equivalent to large, but the hardness exceeds the hardness of the lathe turning tool, and the processing cannot be performed. Not only will the lathe turning tool be damaged, but also It will also cause dangers such as broken turning of the turning tool.

4. Summary

Precision mechanical parts processing has certain requirements for material quality, and not all materials are suitable. If the material is too soft, there is no need for precision machining. If the material is too hard, the lathe tool cannot be processed. In short, when processing precision mechanical parts, the hardness of the processed material must be lower than the hardness of the lathe tool to perform precision machining.
