Diamond and CBN wheels
Bond type of Diamond and CBN wheels
Diamond and CBN wheels come in several bond types: Resin (most common), vitrified, metal, hybrid and electro-plated. Resin is used in most tool room and production applications. Vitrified, metal and hybrid bonds are newer bond types with specific applications (We won't go into a lot of detail with these as they are somewhat rare and more expensive and almost always are custom made special order items). Electro-plated wheels are very common and are typically found in cutoff wheels and low demanding abrasive grinding such as for plastics.
Resin wheels are made much like a traditional grinding wheel with a thick bond/grit layer usually between 1/16" and 1/4". Electroplated wheels are a much thinner thickness. In both cases, the bond layer is applied to a hub which is either aluminum or steel made to the specific profile required.
Like traditional grinding wheels, Diamond and CBN wheels are used in a variety of processes and with a variety of materials. Typically, diamond wheels are used strictly on carbides and CBN is used on steels. Some manufacturers produce a 'hybrid' wheel which is a special grit that will grind both steels and carbides (Typically used on parts that require grinding of carbide and steel at the same time). Plated diamond wheels are used on non-ferrous materials such as plastics, rubbers, nylons, fiberglass, etc.
