Because the area Ao of the end surface of the small axle is less than that of the heating section area ofthe conventional inductor of the high frequency induction hardening ,the end surface will be overheated or burnt at thecorner or underhardened at the centre due to skin effect and corner effect.

Material Selection and processing of small gear shaft in drilling pump;

For resolving efficiently the problem of machining errors that are caused by bending deflection of weak stiffness shafts,this paper has analyzed machining errors of the workpiece by calculating the bending deflection based on reasonable selecting the technological parameters,and offered specific measures of error control——to compensate the errors by macro programming.
