There are many reasons for the wear of turning tools on CNC lathes, including the following:

1. Effect of cutting force: During the processing of CNC lathe, cutting force is one of the main forces, which directly acts on the tip and edge of the turning tool. Long-term high-speed cutting will cause wear on the surface of the turning tool.

2. Uneven material hardness: When the workpiece material processed by a CNC lathe has uneven hardness or contains hard particles, it will increase the wear of the turning tool.

3. Tool quality: The material, manufacturing process and quality of CNC lathe tools directly affect their wear degree. Low-quality tools are prone to wear during machining.

4. Improper setting of cutting parameters: Improper setting of cutting parameters such as CNC lathe cutting speed, feed rate, and cutting depth will cause the turning tool to be subject to additional heat and force, accelerating wear.

5. Poor lubrication: The lack of proper lubrication and cooling of the CNC lathe will cause the surface of the turning tool to overheat and increase the wear rate.

6. Tool service life: After the service life of a CNC lathe tool reaches a certain level, its cutting edge will gradually become blunt and wear will increase.

7. Processing environment: Factors such as the cleanliness, temperature and humidity of the CNC lathe processing environment will affect the wear of the turning tool.

8. Cutting methods: Different cutting methods of CNC lathes, such as rough machining, finishing machining, etc., will have varying degrees of impact on the wear of turning tools.

Therefore, in order to reduce the wear of turning tools, CNC lathes need to choose appropriate tool materials and manufacturing processes, set cutting parameters reasonably, maintain good lubrication and cooling conditions, regularly check and replace turning tools, and at the same time pay attention to improving processing quality and environmental cleanliness. .
