Precision machining, not all materials can be precision machined. Some materials are too hard to exceed the hardness of machining parts, which may break the parts. Therefore, these materials are not suitable for precision Sheet Metal Parts, unless they are parts made of special materials or laser cutting.
Materials for precision metal plate parts are divided into two categories, metallic materials and nonmetallic materials.
For metal materials, stainless steel has the highest hardness, followed by cast iron, copper and aluminum.
The processing of ceramics, plastics, etc. belongs to the processing of nonmetallic materials.
Stainless steel material for precision metal plate parts
1. The first is the requirement of material hardness. For some occasions, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the processing parts. The processed material cannot be too hard, if it is even harder than the parts.
2. Secondly, the material is moderately hard and soft, at least one grade lower than the hardness of the machine parts. At the same time, it also depends on what the function of the machine parts is to do and the reasonable selection of materials for the machine parts.
In a word, there are still some requirements on materials for precision Bakelite Parts. Not all materials are suitable for processing, such as too soft or too hard materials. The former is not necessary for processing, while the latter cannot be processed.
Therefore, the most basic one is that we must pay attention to the density of the material before processing. If the density is too high, it is equivalent to high hardness. If the hardness exceeds the hardness of the machine parts (lathe tools), it cannot be processed. It will not only damage the parts, but also cause danger, such as the lathe tools flying out and hurting people. Therefore, generally speaking, for mechanical processing, the material should be lower than the hardness of the machine tool, so as to be processed.
