The applications of single crystal diamond cutting tools
Single crystal diamond tools have high processing accuracy and long service life, and are widely used in ultra-precision cutting. In recent years, products processed with diamond tools (such as contact lens lenses, Fresnel lenses, photosensitive drums for copiers, etc.) have increasingly entered ordinary homes and workplaces.
Different Single crystal diamond sharpening process
There are currently many process methods used for sharpening single crystal diamond tools, such as mechanical sharpening, ion beam sputtering, focused ion beam sputtering, femtosecond laser etching, thermo-mechanical coupling process, etc. Mechanical sharpening is a commonly used sharpening method and has the advantages of simple process, low cost, and high processing efficiency.
Removal mechanism of diamond crystal surface material
The removal mechanism of diamond crystal surface material is: in the easy-to-wear direction (〈100〉 direction) of the diamond crystal, the main allotropic transformation occurs, that is, the sp3 carbon atom hybridization of the diamond crystal changes to the sparse amorphous sp2 carbon atom hybrid. Chemical transformation; in the difficult-to-grind direction (<110> direction) of the diamond crystal, it is mainly cleavage fracture on the micro scale, mainly brittle fracture with nanoscale micro cracks.
Factors affecting the sharpening accuracy of single crystal diamond tools
1.Selection of grinding surface and grinding direction
2.Grinding paraments:grit of diamond grinding wheel;Sharpening line speed;sharpening pressure;grinding machine vibration

In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
