Metal bond diamond and CBN grinding wheels are made from the sintering of metals powder and other compounds with either Diamond or Cubic Boron Nitride (CBN). Metal bond grinding wheels have features of high efficiency, good self-sharpening, high stock removal, strong hold and good abrasion resistance. One weakness to be aware of with metal bond grinding wheels is that they are not easily dressed. Metal bond grinding wheels mainly used for machining quartz crystal, tungsten carbide, ceramics, glass, composite, sapphire, ferrite refractory, thermal spraying materials, high speed steel, tool steel, mould steel. stainless steel, titanium alloy, cast iron and so on
