Abrasive process of existing teeth sharpened with helical tool shaped like the tooth profile. Beskrivning The process Before grinding can be carried out, most of gear profile material has to be removed by gear forming method as this method only hone the teeth surface. The workpiece is fixed on a vertical rotating shaft and the grinding tool in a horizontal axis. The rotation of these axes are coordinated so that the workpiece edge is fed at the same rate as the helical form of the tool. The workpiece must often be rotated several turns to sharpen whole surface of the teeth. The angle between the shafts is adjusted depending on the angle of the gears desired.
