Zhengzhou RJ Diamond Co., Ltd. (short in “RJ”) specializes in research, development, manufacture, and marketing of super abrasive materials and products. Our products include Diamond Wire Drawing Die Blanks, PDC, PCD&PCBN Cutting Tool Blanks, Diamond& CBN Micron Powder and other PCD and PCBN related products, which are widely used in various industries such as wire drawing, oil drilling, coal mining, geological prospecting and drilling, glass and ceramic cutting, abrasive tools and materials.

RJ provides both resin bond diamond grinding wheels and vitrified bond diamond grinding wheels. 1. Resin Bond Diamond Wheels Resin Bond Diamond Wheels have a special function of self-shaping, sharp-cutting, high-efficient grinding. It is not easy to destroy and heat the work piece in grinding. After grinding, the work piece¡¯s surface is fine and smooth. Resin Bond Diamond Wheel are mainly used in grinding carbide, vitrified, magnetic, silic, self-fluxing alloy material. 2. Vitrified Bond Diamond Grinding Wheels The Vitrified Bond Diamond Grinding Wheels feature with high strength, high heat resistance, excellent cutting ability and high grinding efficiency, therefore, heating up or blacking is not easy to occur in the grinding process, and the low thermal dilation provide a high possibility of free control of process precision. Vitrified Bond Diamond Grinding Wheels are applied in many hard and brittle material machining, such as wafer (semiconductor silicon slice and solar energy silicon slice),polycrystalline diamond compact(PDC),polycrystalline diamond(PCD),PCD tools, tungsten steel(cemented carbide),new emerging structure ceramic, precious stones, crystal, rare earth materials(magnetic material),and etc. Vitrified Bond Diamond Grinding Wheels have the following characteristics: 1. High grinding efficiency. 2. High abrasion resistance, it is obvious when grinding hard and fragile work piece. 3. High grinding precision. 4. No pollution. The Vitrified Bond Diamond Grinding Wheels will not produce smoke in the process of grinding£¬therefore£¬it can meet the requirement of environmental protection. 5. Low labor intensity. The vitrified wheel needs no dressing generally in the using process, thus it has lowered the labor intensity.
