Solution:

Tool selection: Based on material properties and chamfering parameters, choose hard alloy and coated machining tools. During grinding, the tools remain sharp and stable, which can effectively remove burrs.

Grinding processing: Before or after chamfering, grinding processing can be carried out to remove burrs and edges on the surface of the workpiece, improve the surface quality and sharpness of the workpiece.

Setting cutting parameters: During machining, cutting parameters such as cutting speed, feed rate, and cutting depth have an impact on the quality of chamfering. Reasonably adjusting these parameters can improve the quality of the processed workpiece.

Cooling and lubrication: During the chamfering process, the workpiece and tool generate high-energy heat, which can easily cause problems such as tool sticking and tooth breakage. The use of cooling lubricants can reduce friction between the tool and workpiece, lower temperature, and help maintain the sharpness of the tool and product.

Electrochemical machining: The batch edges left behind after CNC chamfering of the workpiece can be well removed by the chemical action of the electrolyte.
