325/400 Resin Bond Mesh Diamond Powder Grade BRD10 For Grinding

325/400 Artificial Diamond Lapping Powder Ultra Fine Abrasive

Description:

Diamond powder is a new type of super-hard and ultra-fine abrasive formed by special processing and processing of synthetic diamond single crystals. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gems, and optical glass. Diamond tools and other products are made of diamond, which are widely used in all kinds of industries.

BRD series are polycrystalline-like diamond graine, mainly used in resin bond diamond grinding wheels. Harmony Industry Diamond (H.I.D.) boron doped technology largely improve BRD series bond strengh accordingly, elevate bond retention capabilities to crystal. Polycrystalline-like diamond graine is composed of sub-crystals with mosaic structure that provides the graine with irregular shape and rough surface. Polycrystalline-like diamond can keep consistency of self-sharpening and sharp cutting edges.

There are two main methods of synthetic diamond, high temperature and high pressure method and chemical vapor deposition method.
The high temperature and high pressure method technology has been very mature and has formed an industry. The domestic output is extremely high, the highest in the world. The chemical vapor deposition method still mainly exists in the laboratory.
It's widely used in geological drill and petroleum drill diamonds, diamonds for wire drawing dies, diamonds for abrasives, diamonds for dressers, diamonds for glass cutters, diamonds for hardness testers, diamonds for handicrafts. If it is painted on the speaker cone, the sound quality of the speaker will be greatly improved.

Characteristics:

- Strong cutting force: There are a large number of sharp cutting edges on the surface of particles, and the cutting force can reach 2-4 times that of single crystal diamond powder.
- High polishing accuracy: The cutting edge of single crystal diamond powder is large and hard, which is prone to deep scratches. The cutting edge of polycrystal-like diamond powder is small and its hardness is low. The Ra value of workpiece surface after polishing decreases significantly.
- Strong grip strength: rough surface of particles and stronger bonding with binder can significantly improve grip strength of abrasives in various diamond products and improve service life.
