In the building of machines and automobiles, the individual components of gear wheels and gear racks are particularly important. Their production is commonly undertaken by a gear cutting machine. Gear wheels are made using two processes. First of all they are milled and then ground. Depending on their prospective use, different types of machines could be used for said process. For the milling of gear wheels, hobbing processes are used.

High numbers of gear edges can be deburred and sharpened efficiently using this process. The machines contain NC or CNC-control, which eases the operation. A hobbing machine is used for the manufacturing of external teeth, as well as spur and helical gears. For workpieces with large diameters, internal helical gears are possible. Crown wheels and bevel gears can also be produced using this machine. Smaller internal gears cannot be produced using this process and therefore, hobbing in conjunction with special machines is used for this purpose. The hobbing machine is very flexible in terms of its settings, and can take up a large row of variously arranged tools.

A robust machine body hosts the individual machine components. This component operates the hob and also the movable clamping slide or chuck for the workpiece. A cooling system is usually integrated within the casing. There is a difference between horizontal and vertical machines. Particularly precise tooth flanks can be achieved if the tooth flanks are first milled and then the gear wheel is hardened. Thereafter, the special tooth flank grinder can create the final contours.
