Why does CNC machining produce burrs?

First, the cutting force is too largeIn the process of CNC machining machine tools, if the cutting force is too large, it will lead to large plastic deformation when the material is cut, so that burrs are easy to appear. The reasons for excessive cutting force mainly include different hardness of materials, poor quality of processing tools, and unreasonable processing equipment.

Second, the cutting speed is too slowToo slow cutting speed is also one of the causes of burr formation. When the cutting speed is too slow, the material will generate excessive heat during the cutting process, which accelerates the deformation of the material and leads to the formation of burrs.

Third, tool wearThe more severe the tool wear, the more burrs the CNC machine tool produces during processing. Tool selection, life, use and maintenance will affect the cutting effect, thus affecting the generation of burrs.

Fourth, the hardness of the material is differentThe hardness of materials is also one of the reasons for the formation of burrs in CNC machining machines. When the hardness of the material is not equal, it will lead to the uneven distribution of burrs during the processing, thus accelerating the formation of burrs.

Fifth, poor lubrication during processingPoor lubrication is also one of the causes of burrs in CNC machine tools. When the equipment is not lubricated properly, a lot of heat will be generated during cutting, resulting in the formation of burrs.

In general, the cause of burr formation of CNC machine tools is complex, and it is necessary to analyze and control according to the actual situation. These reasons include too much cutting force, too slow cutting speed, tool wear, material hardness, etc., for these problems to be adjusted and improved properly to improve processing efficiency and production quality.
