In the field of mechanical processing, CNC lathes have become indispensable and important equipment. However, when using CNC lathes for processing, broken tools are a common problem, which not only affects production efficiency but also increases production costs. Therefore, how to prevent CNC lathe tool breakage has become an important issue.

 First, choose the right tool. Factors such as the material, geometric angle and coating of the tool will affect its service life. During the processing process, try to choose tools with high hardness and high wear resistance, and at the same time ensure that the geometric angle and coating quality of the tool meet the processing requirements. In addition, the specification and model of the tool should be reasonably selected according to the processing materials and process requirements to avoid using inappropriate tools that may lead to tool breakage.

Secondly, the cutting parameters must be set reasonably. Cutting parameters are one of the important factors that affect tool breakage, including cutting speed, feed speed, back cutting amount, etc. During the machining process, the cutting parameters should be adjusted reasonably based on the actual conditions such as material hardness, cutting depth, and tool performance to avoid tool breakage due to improper cutting parameters.

Third, ensure an adequate supply of coolant. Coolant can effectively lower cutting temperatures, reducing tool wear and the risk of tool breakage. Therefore, during the machining process, it is necessary to ensure an adequate supply of coolant, and at the same time, select the appropriate type and concentration of coolant to ensure a good cooling effect.

Finally, the inspection and maintenance of cutting tools should be strengthened. Tool wear and damage is one of the main causes of tool breakage. Therefore, tools must be inspected and maintained regularly, and worn and damaged tools must be replaced in a timely manner to ensure the stability and safety of the processing process.

In short, preventing CNC lathe tool breakage requires starting from many aspects, including selecting appropriate tools, reasonably setting cutting parameters, ensuring an adequate supply of coolant, and strengthening tool detection and maintenance. Only by comprehensive consideration and effective measures can we effectively reduce the risk of tool breakage and improve the processing efficiency and stability of CNC lathes.
