What Are The Requirements For Precision Machining Parts?
Jun 13, 2017

Precision machining parts, not what materials can be precision machining, and some materials too much hardness, more than the hardness of the processing machine parts, it may collapse the mechanical parts, so these materials are not suitable for precision machining, unless it is Special materials made of mechanical parts, or laser cutting.

For Precision Machining Parts of mechanical processing materials are divided into two categories, metal materials and non-metallic materials.

For metal materials, the hardness of the largest stainless steel, followed by cast iron, followed by copper, and finally aluminum.

The processing of ceramics, plastics, etc. are non-metallic materials processing.

1. First of all, the requirements of the hardness of the material, for some occasions, the material is the hardness of the higher the better, but limited to the hardness requirements of processing parts, precision machining parts of the material can not be too hard, if the machine is hard to work of.

2. Second, the material soft and hard moderate, at least lower than the mechanical hardness of a grade, but also depends on the role of processing equipment is what to use, the rational selection of mechanical parts.

In short, the Precision Machining Parts of mechanical processing of the material requirements or some, not what materials are suitable for processing, such as too soft or too hard material, the former is not necessary processing, while the latter is unable to process.

Therefore, the most basic one is that before the precision machining parts must pay attention to the density of materials, if the density is too large, the hardness is equivalent to a large, and if the hardness of the machine (lathe turning) hardness, that is, , Not only will damage the parts, but also cause danger, such as turning out of scissors and so on. Therefore, in general, for mechanical processing, the material material is lower than the hardness of the knife, so as to be processed.
