What properties should the selected materials meet in the manufacturing process of mechanical blade

　　In recent years, China's mechanical development has made rapid progress. Both the accuracy and cost of machine tools are more accurate step by step, and the price is also slowly declining. Although China is still in the development stage in the major high-precision and precision machine tools, we have been in a state of rapid progress in the process of development.
　　For all kinds of machine tools and processing machines, the wear of mechanical blades is large. Fortunately, because China attaches great importance to mechanical development in recent years, our country can develop and manufacture these mechanical blades by itself. However, in the process of manufacturing and design, we should also pay attention to performance.
　　Performance is an important attribute of mechanical blade. From the perspective of manufactured parts, it can be generally divided into sufficient hardness and strength of blade, toughness of blade and high temperature resistance of blade. Sufficient strength and hardness can ensure that the blade is not easily damaged by the workpiece in the process of contact with the workpiece, but it will wear the mechanical blade under long-term processing, so the mechanical blade should be replaced regularly. The high temperature resistance of the blade is also an important content in the process of early blade manufacturing. The workpiece runs at high speed in the machine and will produce considerable friction with the blade. If the material of the blade itself does not have high temperature resistance, it may fuse in the processing process.
