The superior features of a single crystal diamond chamfering knife when cutting mainly include:

1, high sharpness: the cutting edge of a single crystal diamond tool can be sharpened very sharp, so when chamfering, you can obtain a smoother cutting surface and a more accurate cutting size.
2, low friction coefficient: the friction coefficient of the single crystal diamond tool is low, so the heat generated during the cutting process is less, which can reduce the deformation and burn of the workpiece, and improve the cutting accuracy and efficiency.
3, the cutting force is small: due to the low friction coefficient of the single crystal diamond tool, the cutting force will be relatively small under the same cutting conditions, which helps to reduce the wear of the tool and the deformation of the workpiece.
4, high machining surface quality: When using single crystal diamond cutting tools for chamfering, you can obtain higher surface quality, such as smoother cutting surface and smaller roughness.
5, high processing efficiency: due to the advantages of high sharpness, low friction coefficient and small cutting force of single crystal diamond tools, the cutting speed can be faster and the processing efficiency can be improved.
6, a wide range of applications: single crystal diamond tools can be applied to cutting a variety of materials, such as metal, non-metal, ceramics, etc., so in different application scenarios can play its superior performance.

In summary, the single crystal diamond chamfering knife has the advantages of high sharpness, low friction coefficient, small cutting force, high machining surface quality, high processing efficiency, and wide application range when cutting, which make it widely used in various material cutting fields.
