The results show that upper bainite of 9Cr2Mo Steel and GCr15 steel is feathery and the upper bainite carbide is lamellar or claviform. The upper bainite carbide distributes between the subunits of bainite ferrites by and large parallelly to the axis of bainite ferrites. Lower bainite of 9Cr2Mo Steel and GCr15 steel is in bamboo leaf shape and the lower bainite carbide is in shred or fibre shape. The lower bainite carbide distributes between the bainite ferrites, furthermore, the angles between lower bainite carbonide and the principal axis of the lower bainite ferrites are unequal.

On the basis of previously research, this paper re-probe into the mechanism of electro-chemist mechanical manufacturing process, making the rational technological parameter, and developing the manufacturing equipment. Through a lot of technology tests, get a lot of labratory data, accordingly, researched the surface feature of the electro-chemist manufacturing process, and deeply discussed its influence on the work piece feature. The last result is that: the electro-chemist mechanical manufacturing process can reduce the low-frequency component significantly, but on high-frequency component, it has little influence, having obviously positive pole flat effect. After manufacture, the tip parts on the surface of the work piece is cut off, there is micro "high land" shape, the parameter for surface roughness is reduced a lot, the surface outline of the work piece is negative, the bearing length rate is cliffy. Also the surface quality of the work piece is improved. This can help to avoid changing the shape, improve the feature of rub, gear and reduce the time to suit. This would also ensure the precision and result in a longer work piece life.

The evaluation method and algorithm of shape error (roundness, plane straightness, space straightness, cylindricity) were discussed. A new kind of algorithm, namely mesh searching method, which can be used to evaluate the roundness error, plane straightness error, space straightness error and cylindricity error, were put forward. With this algorithm, the shape error can be obtained by transferring the distance formula repeatedly and simple judgment without linearzing the distance formula (from point to point or point to line) and choosing optimal direction and step length.
