Tooth profile machining is the key factor of gear machining, selection of 3312 bearing number details the scheme depends on many aspects, such as equipment, gear precision, surface roughness, hardness etc.. Tooth shape processing schemes used in existing on the upper section, this is no longer the.

Tooth gear machining is round, pour point, chamfering and deburring etc.. The rounded tip, but the gear easily into engagement in the shift, reduce the impact phenomenon. Chamfering tooth end corners and burrs removed. Is finger milling cutter for processing rounded on the tooth end. Rounded, cutter told rotation, and swing along the arc, finished a tooth, workpiece retreated from the milling cutter, the indexing and fast into the cutter near processing under a tooth end.
The tooth end processing must be carried out prior to 3312 bearing number details quenching, usually in a rolling (plug) tooth, shaving before tooth end processing.
Heat treatment 4, wheel machining process requirements
In the gear machining process, heat treatment process of the arrangement is very important, it directly affects the mechanical properties and machining gear. In general for two kinds of 3312 bearing number details heat treatment process in the gear processing, i.e. rough heat treatment and the tooth shaped heat treatment
