CBN paste has high thermal stability and chemical inertness, making it difficult to chemically react with elements such as iron metal. CBN paste possesses excellent lubricating and cooling properties. It is suitable for processing hard and tough materials (such as steel tools, steel tool modules, stainless steel, and heat-resistant metal alloys) and iron metals. We can provide both oil-based and water-based types.

Diamond paste is available in two types: oil-based and water-based. The oil-based paste is suitable for lapping hard materials (such as hard alloys, alloy steel, and carbide steel, which are brittle materials). The water-based paste is suitable for lapping surveying tools, cutting tools, and optical instruments made from metallographic, rock, and superhard materials (such as glass, ceramics, hard alloys, and natural gemstones).

Features: Diamond slurry is a mixture of carefully selected high-quality diamond abrasives with liquids such as water or oil. It is widely used for polishing hard materials such as silicon wafers, gemstones, optical lenses, ceramics, hard disks, and hard alloys. Depending on the type of diamond, there are three varieties: single crystal, polycrystalline, and nano. We also provide original polishing slurry tailored to the products you handle.

The cobalt layer enhances the static pressure strength and retention of diamond abrasives. Additionally, the cobalt on the surface increases the temperature at which the diamond abrasives undergo graphitization, expanding the necessary temperature range for the sintering of diamond tools.

Tungsten easily bonds with the bond, so the tungsten layer enhances the bonding strength between the diamond abrasive and the bond. Tungsten and diamond abrasives form tungsten carbide, which is a main component of hard alloys, providing excellent wear resistance and thermal conductivity. In particular, this excellent thermal conductivity quickly transfers the heat generated during work, preventing the carbonization of the diamond abrasives and extending the tool's lifespan. It is applied in the manufacturing of cutting tools for reinforced concrete.
