Knife breakage is one of the common problems in CNC lathe processing. The following methods can be used to prevent and reduce the occurrence of tool breakage:

1. Correctly select the tool: CNC lathe selects the appropriate tool type, specification and material based on the processing material, processing technology and processing requirements. Ensure that CNC lathe cutting tools have sufficient rigidity and wear resistance to adapt to the requirements of processing conditions.

2. Reasonably set cutting parameters: CNC lathes reasonably set cutting speed, feed speed, cutting depth and other processing parameters according to the processing materials and processing technology. CNC lathes should avoid setting excessive cutting parameters to avoid excessive tool wear and breakage.

3. Keep the cutting tools sharp: CNC lathes regularly check and maintain cutting tools to ensure that the cutting edges of the cutting tools remain sharp. Regularly grind and replace cutting tools to maintain cutting performance and processing quality.

4. Regular lubrication and cooling: CNC lathes regularly lubricate and cool the cutting tools and processing areas to reduce friction and heat accumulation and reduce the risk of tool wear and breakage. Ensure the normal operation of the lubrication and cooling system, and replace lubricating oil and coolant in a timely manner.

5. Monitor the processing process: Use the CNC system to monitor the processing process and detect processing abnormalities and tool wear in a timely manner. Adjust processing parameters based on monitoring results to ensure processing quality and tool life.

6. Reduce process impact: CNC lathes should try to avoid process impact and vibration during processing, such as avoiding rapid changes in processing parameters, reducing tool feed impact, etc. Reducing process shock reduces the risk of tool wear and breakage.

Through the above preventive measures, CNC lathes can effectively reduce the risk of CNC lathe tool breakage, improve processing efficiency and quality, extend tool life, and reduce production costs.
