Gear wheels and worms transmit torque to other gears or gear racks or chains. Gears are specified by diameter, number of teeth and shape of teeth. Gears can be designed spur or helical, spiral or hypoid. The shape of the teeth is defined by pitch, teeth width and teeth gap, teeth flank and face, bottom land and top land. In any case, the shape of the gear teeth or gear cogs must be designed so that the frictional connection is form-fitting, seamless and without slip. The precision of the tooth shape determines the quality of the gear. Gear blanks can be prepared in many ways. The precise surface shape is often produced by grinding. Then curing and hardening of the gears is necessary and sometimes the gears need to be re-ground afterwards again.
Depending on the design of the gears and on the shape of the teeth, different grinding wheels are used. Kinik specializes in grinding wheels for grinding of gears and can guarantee high removal rates and long grinding wheel life as well as high grinding precision and minimal surface damage. Grinding wheels for Reishauer, Pratt and Maag systems can be offered.
The purpose of the dressing and truing is to restore the original cutting geometry and to correct the flatness and roundness of the grinding wheel. This is done in many cases by diamond dressers.
Grinding machines can be equipped with different grinding wheels. The grinding wheels can consist of aluminium oxide Al2O3, cubic boron nitride cBN or diamond. cBN and diamond grinding wheels are very hard and can be used for high precision grinding of very hard parts. The life time is very high. Diamond wheels have some limitation for grinding steel because of the solubility of carbon in iron.
The grain size of the abrasive material of a grinding wheel is determined by the mesh size of the sieve that is used for the selection of the material. The mesh size is therefore a measure of the roughness of the grinding wheel and determines the removal rate and the surface roughness of the workpiece after grinding.

Bonding of the abrasiv material can be vitrified, metallic or resin. Vitrified bonding is used frequently. High stock removal rates can be achieved and the rigidity allows high precision grinding. This bonding is not sensitive to water, acid, oil and it is not temperature sensitive either. Resin bonding is rather soft and is used to achieve very smooth surfaces. Metallic bonding is used for special purposes, e.g. for electrical discharge truing. Regulation and feed wheels use rubber bonding.
