JCB JCD Series Diamond Crushed Material is produced using JCB JSD Series coarse-grained single crystal synthetic diamonds as raw materials, undergoing processes such as crushing, purification, shaping, and sieving to create super-hard grinding and polishing materials. This product features irregular crystal shapes, low impurity content, a rough and sharp surface. The JCD Series Diamond Crushed Material from JCB is primarily used in the manufacture of diamond grinding wheels, diamond abrasive wheels, diamond segments, and other diamond cutting and grinding tools with resin, ceramic, or metal bonding agents. Compared to primary single crystal fine powders, it offers both economic advantages and superior grinding properties.
JCD-A Features: Made from coarse-grain, high-strength single crystal synthetic diamond JSD30 through processes including crushing, purification, shaping, and sieving, this super-hard abrasive material presents irregular crystal shapes, low impurity content, low magnetism, and a rough, sharp surface. Applications: Primarily used in heavy load ceramic bonded grinding tools, medium load metal bonded grinding tools, and electroplating grinding tools for processing non-metals like glass, ceramics, and stone. Offers better economy and grinding performance compared to the original fine-grained JSD30 single crystal. | |
JCD-B Features: Derived from coarse-grain, premium single crystal synthetic diamond JSD20, processed through crushing, purification, shaping, and sieving, it is a super-hard abrasive material characterized by irregular crystals, minimal impurities, low magnetism, and a rugged, keen edge. Applications: Mainly utilized in medium load ceramic and metal bonded grinding tools, as well as electroplating grinding tools for non-metallic materials such as glass, ceramics, and stone. Provides improved economics and grinding properties versus the native JSD20 single crystal fines. | |
JCD-C Features: Utilizing coarse-grain, high-quality single crystal synthetic diamond JSD10 as the base, refined through crushing, purification, shaping, and sieving, this super-hard abrasive material boasts irregular crystal structures, low impurity levels, low magnetic susceptibility, a rough and sharp texture. Applications: Suited for heavy load resin-bonded, medium load ceramic bonded, and light load metal bonded grinding tools in the machining of gems, glass, optical glass, ceramics, stone, etc. Offers enhanced economy and grinding efficiency over the original JSD10 single crystal fine powder. | |
JRD Features: Using coarse-grain, high-quality resin-bonded synthetic diamond JRD as the raw material, this super-hard abrasive material is processed through crushing, purification, shaping, and sieving. It has irregular crystal forms, is yellowish-green in color, possesses low impurity content, a rough and sharp surface, and excellent self-sharpening properties. Applications: Suitable for heavy load resin-bonded and light load ceramic bonded grinding tools, ideal for grinding brittle materials like gemstones, stone, ceramic tiles, glass, optical glass, and rough machining of cemented carbide. As an economical resin diamond, it offers high grinding efficiency. |
