Advantage of the present utility model:

1, simple in structure, bearing capacity is strong, the positioning accuracy height, and rigidity is strong, and serviceability is reliable and stable, and is easy to operate, and cost is low, and working (machining) efficiency improves more than 5 times.

2, be furnished with two main spindle boxes, promptly by interior external tooth machining spindle case and external tooth machining spindle case, change external tooth machining spindle case when the external toothing diameter surpasses certain limit, the straight-tooth helical teeth all can be processed simultaneously, has enlarged the range of work.

3, horizontal slide clamps and the clamping of vertical sliding clamping employing butterfly spring, and hydraulic unlock reduces the leakage of pressure oil to greatest extent, helps environmental protection and saves the energy.

4, be applicable to gear ring processing of wind-power electricity generation machine bearing and Transport Machinery, engineering machinery, external tooth processing in mine industry etc. are cylindrical.
