The majority of the components on order are toothed (they include every known type of toothed elements of cylinder, spiral, worm and bevel gears, as well as toothed parts belonging to them as complementary elements – requiring outstanding expertise-, spiral gears, multiple-start worms, splined components, special epicycloid bevel gear wheels, hypoid bevel gears, but also simpler spur-gears with straight and helical toothing or bevel gears with straight toothing.
All these components constitute a special group of machine components which require a particularly high level of expertise and experience.
