In recent years, our country's mechanical development has been advancing by leaps and bounds, whether it is the accuracy of the machine tool or the cost of the machine tool is more accurate step by step, the price is also slowly declining, although in the major high-precision and ultra-precision machine tools, our country is still in the development stage, but in the process of development, we have been in a state of rapid progress.

　　As far as the current various machine tools and processing machines are concerned, the wear and tear of mechanical blades is very large, but fortunately, because our country attaches great importance to the development of machinery in recent years, our country has been able to develop and manufacture these mechanical blades by itself. But in the process of manufacturing and design, we also need to pay attention to the performance aspect.

　　Performance is an important attribute of mechanical blades, from the perspective of the parts made, it can generally be divided into sufficient hardness and strength of the blade, the toughness of the blade, and the high temperature resistance of the blade. Sufficient strength and hardness can ensure that the blade is not easily destroyed by the workpiece in the process of contact with the workpiece, but under long-term processing, it will cause wear and tear on the mechanical blade, so the mechanical blade must be replaced regularly. The high temperature resistance of the blade is also an important part of the process of early blade manufacturing, the workpiece is running at high speed in the machine, and the blade will produce considerable friction, if the material of the blade itself does not have high temperature resistance, it may be blown in the processing process.

　　The last one, the toughness of the blade, if there is a vibration in the process of processing, it will have a great impact on the blade mechanical blade, if there is no fairly good toughness, the machine tool or other machines will be directly broken while the machine tool or other machines are vibrating.
