30-40um Grade HID A+ Monocrystal Metal Bond Micron Diamond Powder

Monocrystalline 30-40 Micron Diamond Powder Metal Bonded

Description:

Diamond powder is mainly used for fine grinding, grinding and polishing of non-metallic hard and brittle materials. Generally, 0~0.5 μm to 6~12 μm is used for polishing, 5~10 μm to 12~22 μm is used for grinding, and 20~30 μm is used for coarse grinding. Diamond powder is mainly used in the following four aspects: (1) Direct use to make abrasive paste. It is widely used in the polishing of cutting tools, measuring tools, optical instruments, electronic devices and other precision parts made of cemented carbide, high-alumina ceramics, optical glass, instrument gems, semiconductors and other materials, and its processing roughness can reach mirror surface. (2) It is widely used in the manufacture of precision grinding discs, super precision grinding discs, and electroplating products. (3) Used to manufacture polycrystalline diamond sintered bodies, such as geological and petroleum drill bits, cutting tools, wire drawing dies, etc. (4) Used in the manufacture of grinding fluid and polishing fluid.

Using high-quality diamond as raw material, through our advanced technology of the precise and strict control of diamond particle classification, diamond strength, crystal shape and purity, we have achieved very narrow PSD, consistant crystal shape, extremely high particle surface purity, oversize control, and batch quality consistency.Using high-quality diamond as raw material, through our advanced technology of the precise and strict control of diamond particle classification, diamond strength, crystal shape and purity, we have achieved very narrow PSD, consistant crystal shape, extremely high particle surface purity, oversize control and batch quality consistency.

Application: Suitable for resin bond abrasive tools, all kinds of electroplating tools, grinding paste and slurry.

Characteristics:

For the particle shape of diamond powder, it is better to use approximately spherical particles and an equal area shape during polishing. In the micropowder standard, needle-shaped particles refer to the ratio of the major axis to the minor axis exceeding 3:1. Needle-rod-shaped particles exceeding the maximum particle size cannot be contained in the micropowder, but needle-rod-shaped particles with a length between the maximum nominal size and the largest particle are allowed not to exceed 3%.
Observed under a microscope through light transmission, they are transparent flake particles, and those with a size smaller than D5 can be disregarded. The flake particles in fine diamond powder do not exceed 5%.

Application for Micron Diamond Premium Grade HID A+:

- Traditional gem polishing: single crystal powder or abrasive paste of about 3um is traditionally used
- Raw material for sintering PCD: Micron-sized powder is expanding with the application of PCD tools.
- Grinding and polishing of sapphire wafers: micron to sub-micron, polycrystalline/single crystal polishing liquid is developing rapidly with LED.
- Grinding and polishing of optical fiber connectors: micron to sub-micron, polishing film.
- Ceramic processing: single crystal or polycrystalline powder can be used. For example, fiber ceramic ferrule: single crystal powder from micron to sub-micron, application products include grinding wheel, grinding fluid, polishing film. The application prospects in this area are good.
- Magnetic head: such as grinding and polishing of GMR magnetic head, submicron ~ nanometer, polishing liquid/polishing film.
- Grinding and polishing of super-hard metal rollers or devices: micron to sub-micron, polishing film/abrasive paste/grinding wheel develops steadily.
- Polishing of metal molds: micron to sub-micron, diamond polishing liquid/grinding paste is developing steadily.
- Raw materials for various grinding tools: single crystals of various grain sizes, there is still broad room for development!
