Discussion hotting up on burning
		Costly damage has many causes
		As a result of the activities at the Reese hardening plants, the subject of burning on gears has been openly discussed. Dipl.-Ing. Gerhard Reese, manager of the Bochum hardening plant: "The compulsion to enhance the efficiency with increasingly smaller components and weights, and not least of all the pressure of prices on gear manufacturers makes quality assurance an increasingly decisive factor for economic success."

Costly damage Burning is one of the main causes for the failure of heavily loaded gears and takes the form of heat-induced damage to the ground rim zone of the workpiece. Modern instances, for example, affect the gears of wind power stations: there have                  been cases where gear manufacturers had to replace high-quality gears because burning had verifiably caused damage to the tooth profiles.

Many causes There are as many causes of burning as there are input quantities from the grinding process - and their effects are multiplicative: infeed increment, feed rate (metal-removal rate), state of the grinding wheel (loaded, worn, eccentricity), inadequate coolant effects (specifications, additives, pressure, flow rate, arrangement and shape of the nozzles), and the tooth geometry.
