Surface Treatment Process for Machining of Mechanical Parts
In the processing of parts, the requirements for strength and toughness are relatively high. Its working performance and service life are closely related to its surface properties. However, the improvement of surface properties cannot be achieved simply by relying on materials, and it is also a very uneconomical approach. However, in actual processing, its performance has reached the standard. At this time, surface treatment technology is required. Mold polishing technology is a very important link in the field of mold surface treatment, and it is also an important process in the processing of workpieces.
What are the precautions for the processing of mechanical parts
Before machining parts, be sure to pay attention to the density of the material. If the density is too high, it is equivalent to a great hardness. If the hardness exceeds the hardness of the lathe tool, it cannot be processed, which will not only damage the parts, but also cause danger. For example, the knife flies out and hurts people. So, what are the precautions for the material processing of parts? The materials for parts processing are divided into two categories, metallic materials and non-metallic materials. For metal materials, the hardness is stainless steel, followed by cast iron, followed by copper. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials.
