In hard gear process dynamic, hobbed and/or shaped, or warm forged/rolled gears after heat treatment undergo final finishing operation, such as hard finishing, honing, or grinding. Overall economy becomes the deciding factor for selection of the process dynamic.

Worm reduction gearboxes are used to drive heavy duty operations. Worm gearboxes are used when there is a need for increased speed reduction between non-intersecting crossed axis shafts. This type of industrial gearbox uses a worm wheel that has a large diameter. The worm, or screw, meshes with the teeth on the peripheral area of the gearbox.

(thickness 0.25-0.5mm) Grinding can be defined as a material removal process by the abrasive action between rotating abrasive wheel & the work piece. Grinding machine is a power operated machine tool where, the work piece is fed against a constantly rotating abrasive wheel which is also called as Grinding wheel so that a thin layer of material ...
