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
Moresuperhard'customer from Netherlands grinding single crystal diamond tools with ordinary grinder not professional single crystal diamond tools grinding machine.After communicated with customer ,Moresuperhard staff recommand suitable specifications vitrified diamond grinding wheel for them.
Diamond grinding wheel specifications:6A2 D150*H40*T32*W10*X10 5000#
Customer's single crystal tool chipping requirements：There is no chipping when magnified 100 times under Nomarski microscope.
After testing ,Moresuperhard vitrified diamond grinding wheel for sharpening single crystal diamond cutting tools with their ordinary grinder have met their requirements.And the customer immediately placed a new order for 20 ceramic diamond grinding wheels.
Moresuperhard provide vitrified diamond grinding wheel for grinding and sharpening single crystal diamond tools if your grinder can be used with coolant.Moresuperhard vitrified diamond grinding wheel for grinding mcd/cvd diamond cutting tools have many successful grinding cases.Therefor,ordinary grinder also can be used for single diamond tools with vitrified diamond grinding wheel.While,if you want to process high precision single crystal diamond cutting tools,It's necessary to purchase a professional single crystal diamond tool grinding machine.Moresuperhard also provide professional grinding machine for grinding single crystal diamond cutting tools.

Moresuperhard provide quality cnc diamond grinding wheel for grinding rotary cutting tools.1A1,1V1,11V9,12V9 abrasives grinding wheel suit for anca,walter,ewag cnc grinding machine.1. Suitable for high-efficiency grinding processing with rapid feed.2. Good wear resistance and shape retention.3. It has good self-sharpening properties, generates less heat during grinding, reduces burns on the workpiece, and meets the high-precision requirements of the tool.4. No clogging, easy to trim, extend the trimming cycle and reduce processing costs. 5. The cutting edge quality of the grinding workpiece is consistent and the smoothness is high, which ensures stable quality when processing downstream products.
At present, the main diamond processing methods include mechanical polishing, thermochemical polishing, tribochemical polishing, laser polishing, ion beam polishing and chemical mechanical polishing.Due to the anisotropy of diamond, "hard" and "soft" polishing directions have completely different material removal rates.Experimental results show that atomic-level roughness values can be obtained in a shorter time by mechanical polishing in the crystallographic directions <100> and <110> or in another direction deviating from <110> at an angle not exceeding 20°.
