The use of rolling knives has a long history. The first industrial revolution in the West was the addition of rolling knives to the machining process. With the invention of steam engines, telephones, and space shuttles, metal polishing became an indispensable process. The thinking of foreigners is simple and efficient. They came up with a tool that can save time and effort directly, which is what we now call a rolling knife.
Rolling cutters were first introduced to China from the former Soviet Union, and were initially used to process hydraulic cylinders in state-owned enterprises to improve the surface roughness of the cylinder bores. Material surface treatment technology is an important branch of material science. It refers to the use of physical means including mechanical and chemical means to give special properties to the surface of the material without changing the composition and performance of the matrix material. Technology and craftsmanship can satisfy the use of products or parts. Through the application of material surface treatment technology in industry, the quality, performance and life of metal products have been greatly improved, and huge economic benefits have been produced. Therefore, it has attracted the attention of scientific and technological circles in various countries. Surface strengthening refers to a process that improves the surface properties of mechanical parts and components, and improves fatigue strength and wear resistance. Surface strengthening can sometimes improve corrosion resistance. The surface of the load-bearing part is often in a state of maximum stress and works in different media environments. Therefore, the failure and destruction of parts mostly occur on the surface or start from the surface. For example, introducing a certain residual compressive stress on the surface of the part, increasing the surface hardness, improving the surface structure, etc. Can significantly improve the fatigue strength and wear resistance of the part. sex. Surface strengthening methods can generally be divided into surface heat treatment, surface chemical treatment and surface mechanical treatment. There are mainly two methods of surface mechanical treatment: shot peening and rolling knife.
With the progress of the times, the development of industry. Today, the method and efficiency of using rolling knives continue to mature, from multi-pass reciprocating feed extrusion to simple one-step forming. Now many simple holes have become burnt away in one second. Efficient machining technology is also pursued and adopted by more machining workers, and it also meets more customers' product requirements with short processing cycles and high quality requirements.
