How To Choose The Right Diamond And CBN Grinding Wheel? (1)
Dec 21, 2017

Performance instruction

Diamond grinding wheel is the best abrasive tools for grinding carbide, optical glass, ceramics, precious stones and high hardness or brittle non-metallic materials. However, the diamond abrasive is easily carbonized at 700 ° C to 800 ° C, so it is not suitable for grinding steel. The CBN hardness is lower than diamonds, but its thermal stability is good (resistant to high temperature of 1300 ~ 1400 ). It does not decompose in high temperature like diamond, which is the oxidation and graphitization. It is chemically inert to iron group elements, high thermal conductivity (corundum is 46 times). Usually it makes the grinding wheels with long life (up to a few times or a hundred times than corundum wheel), it is to replace corundum wheel grinding hardened steel, high-speed tool steel, bearing steel , stainless steel, heat-resistant steel and titanium alloy high hardness materials.

The binder selection

Superhard abrasive grinding wheel has resin bond, metal bond, ceramics bond, electroplated and brazing. Resin bond grinding wheel is mainly used for sharpening measuring tools, grinding holes, cylindrical grinding and surface grinding. Metal bond grinding wheel is used for cutting into the grinding, optical curve grinding, single-blade grinding, drilling of the spiral groove, but also for electrolytic grinding. Ceramic bond grinding wheel has high grinding efficiency, shape retention, high durability, easy dressing, and long service life. As the ceramic bonding agent has good chemical stability, heat-resisting, oil resistance, corrosion resistance of acid and alkali, it can adapt to a variety of grinding fluid. Also it is low cost of grinding, which has become the first choice for high efficiency, high precision grinding. Electroplated grinding wheel is mainly used for high speed grinding and forming mill, but also for efficient grinding of holes (wet grinding) and use on coordinate grinding machines. Brazed grinding wheels are for ultra-high speed grinding.

JR company specializes in diamond and CBN tools, including resin bond, vitrified bond, metal bond and electroplated grinding wheel.
