Cubic boron nitride (CBN) wheel selection

Cubic boron nitride (CBN) grinding wheel CBN particles stick only on the surface of a thin layer of an ordinary reflex wheel, which abrasive grains toughness, hardness, durability class corundum grinding wheels is 100 times, the most suitable for processing high hardness, tack Large, high temperature strength, low thermal conductivity and high speed steel hard grind or ultra-high speed grinding. Its scope of application and synthetic diamond plays complementary role. Diamond wheel when grinding carbide and non-metallic materials, has a unique effect, but in the grinding steel material, especially when grinding special steel, the effect is not significant. CBN grinding wheel steel wheel efficiency than corundum class higher in recent times, the wheel five times higher than diamond, but less than the diamond grinding brittle material.
Selection and choice of diamond grinding wheel tile granite cutting wheels is similar. But in the binding agent selection, most resin binder, followed by electroplating, metal bond. Vitrified CBN grinding wheel is mainly used for grinding titanium alloys, high-speed steel, malleable iron and other difficult to machine ferrous metals, resin bond CBN grinding wheel for grinding ferromagnetic material is ideal for machining steel. CBN grinding concentration is generally 100 to 150 using more economical, it can not use ordinary cutting fluids, which require special cutting fluid.
