What is the reason for the wear of turning tools on CNC lathes?

CNC lathe is a kind of machining equipment that uses a high-precision computer to control the operation of machine tools. It can accurately control the turning tool to process the workpiece. However, as the machine tool continues to operate, the sharpness of the turning tool will continue to decrease, eventually leading to wear and failure of the turning tool. So, what is the reason for the wear of turning tools on CNC lathes?
First, material factors. The material used in turning tools affects their degree of wear. Commonly used turning tool materials include carbide, high-speed steel, etc. The wear conditions of turning tools for different materials are also different. For example, carbide turning tools wear more slowly than high-speed steel turning tools, but are more difficult to repair when worn.
Second, conditions of use. The load and operating environment of the turning tool during the machining process will also affect its wear. If the material hardness is high, the turning tool is cutting at high speed, or the ambient temperature is too high, etc., it will increase the wear and failure of the turning tool.
Third, the grinding method. The way a turning tool is ground also affects how much it wears. For example, turning tool cutting depth is too large, cutting speed is too fast, cutting times are too many, etc., which will cause turning tool wear to accelerate. In addition, if the lathe operator wears the turning tool improperly, such as wearing it too frequently or using inappropriate grinding tools, it can also cause the turning tool to wear unevenly and fail.
To sum up, the causes of turning tool wear and failure are multiple and compound. Therefore, in daily use of lathes, we must pay attention to the material selection of turning tools, control of use conditions, and correct grinding methods, so as to extend the service life of turning tools as much as possible and improve the production efficiency and processing quality of machine tools.
