Polycrystalline diamond powder

Polycrystalline diamond powder

Grish Company’s polycrystalline diamond powder is created by a special explosive method that instantaneously converts graphite into diamond under high temperature and high pressure due to powerful explosive force. The crystals resemble natural Carbonado. The particle structure of the secondary bonded polycrystals, which lack cleavage, continuously generates new cutting edges, allowing for a high polishing rate, making it ideal for wrapping and polishing processes that require high precision. Additionally, Grish Company manages the quality of all processes from explosive synthesis to refining, cleaning, classification, and product manufacturing, enabling them to propose the most suitable products tailored to customers' applications and needs.

Diamond Gel: A gel type that spreads more than paste or compound.

Formulated with a viscosity softer than paste and harder than slurry! It can be used for tool polishing and mold polishing.

For larger workpieces that require hand polishing, it is recommended for those who struggle with the inability to spread the paste thinly over the entire workpiece and find that the viscosity of standard slurries is too low. It is well-dispersed, so valuable diamond abrasives will not clump together. 【Features】 ■ High-quality finish Using it for mold finishing will elevate the quality of the finish. ■ Customizable liquid properties and size We can deliver a user-friendly 250ml plastic bottle with a cap, blending your preferred diamond powder with a lubricant available in either oil-based or water-based options. ■ Popular product in Japan It is widely adopted by major domestic mold manufacturers and others. While single crystal diamonds can sufficiently polish in hand polishing, if you desire an even finer surface finish, please choose polycrystalline diamonds.

Polycrystalline diamond powder 'DP': Synthetic and ultra-precise classification

Achieve the best surface quality and polishing rate simultaneously in ceramics and hard metal processing! Synthetic polycrystalline diamond powder.

Synthetic polycrystalline diamond powder "DP" is offered in a precise size range of synthetic polycrystalline diamonds. This product, which has undergone our unique precision classification, boasts the highest performance among our diamond powders, providing high polishing rates and surface quality. It can be utilized for lapping and polishing applications of ceramics and hard metals. 【Features】 ■ The highest performance among our diamond powders Delivers unparalleled efficiency and high surface quality. Enables very short polishing times even under low pressure. Additionally, due to self-sharpening action, high polishing rates are sustained. ■ High reproducibility due to unique classification technology The narrow particle size distribution maximizes the number of particles of the same size, reducing the ratio of fine to coarse particles. Strict tolerances significantly reduce variability between lots, resulting in consistent polishing results. ■ Usable for lapping of ultra-hard materials to polishing of precision parts Suitable for lapping and polishing of sapphire, ceramics, ultra-hard materials, soft/hard metals, and synthetic gemstones. *For more details, please refer to the PDF document or feel free to contact us.

Explosive Nano Diamond Powder

Explosive Nano Diamond Powder

The Grish Company’s Kukurasta diamond powder is an artificially synthesized nanodiamond created through detonation in an inert environment. It is formed when carbon instantaneously grows into diamond crystals. Unlike single crystal diamonds produced by conventional graphite static pressure conversion methods, nanodiamonds are rounded and spherical, with a primary particle size of approximately 4 to 7 nm. They are mainly used as additives for ultra-precision polishing, plating, and heat sinks.
