Resin Bond Diamond JBD Series

JCB JBD series resin-bonded synthetic diamond, a form of polycrystalline diamond, is widely utilized in the manufacturing of resin-bonded diamond grinding wheels. Composed of multiple nested subcrystalline structures, the Tianyou JBD series polycrystalline diamond exhibits irregular crystal morphology, a rough surface, exceptional fragility, and superb self-sharpening characteristics. Its distinguished features, including high grinding efficiency, prolonged service life, and excellent finish quality, make it an optimal choice for machining a variety of non-ferrous materials such as tungsten carbide hard alloys, silicon nitride, aluminum oxide, silicon carbide, optical glass, common glass, and ceramics, offering superior performance in these applications

	JBD4(AC4) Characteristics: It is the most brittle and least strong polycrystal among resin-bonded diamonds, with a dark gray color, excellent self-sharpening properties. Its micro-fracturing capability enables outstanding grinding performance under low load grinding. Applications: Suitable for low load resin-bonded grinding tools, used in precision machining of cemented carbides, optical glass, and ultra-high-quality fine grinding applications.
	JBD6(AC6) Characteristics: It is a polycrystal with medium brittleness and strength in resin-bonded diamonds, grayish-green in color, with good self-sharpening properties, offering a balanced choice between grinding effectiveness and tool life. Applications: Applicable to medium load resin-bonded grinding tools for rough and semi-finish machining of cemented carbides, optical glass, and other highly brittle non-metallic materials.
	JRD Characteristics: It is the strongest irregular single crystal in resin-bonded diamonds, yellowish-green in color, with a rough and sharp surface. Applications: Suited for heavy load resin-bonded grinding tools, used in processing gemstones, stone, ceramic tiles, glass, and rough machining of cemented carbides, etc. An economical resin diamond offering high grinding efficiency.
