Precision parts processing, is not what material can be precision processing, precision parts processing material requirements are very strict. So do you know what materials are commonly used in precision parts processing?

For precision machining materials are divided into two categories, metallic materials and non-metallic materials.

For metallic materials, the hardness of stainless steel is the greatest, followed by cast iron, followed by copper, and finally aluminum. And the processing of pottery and porcelain, plastic belongs to the processing of nonmetallic material.

1. The first is the requirement of material hardness. For some occasions, the higher the hardness of the material, the better.

2. Secondly, the material is moderately soft and hard, at least a grade lower than the hardness of the machine parts, but also to see what the role of processing devices is to do with, reasonable selection of materials for the machine parts.

In short, precision machining on the material requirements or some, is not what material is suitable for processing, such as too soft or too hard material, the former is not necessary to process, and the latter is unable to process.

So, the most basic one is, must pay attention to the density of material before processing, if the density is too big, is equivalent to the hardness is also very big, and if the hardness exceeds the hardness of the parts (lathe tool), it is impossible to process, not only damage parts, but also cause danger, such as turning tool flying out of injury. Therefore, generally speaking, for mechanical processing, material material should be lower than the hardness of the knife, so as to be processed.
