1. The application of high speed continuous generating grinding, multi-start worm wheel dressing and grinding technic improve the grinding efficiency greatly.

2. The design of high power, high rigidity of wheel spindle and wide grinding wheel structure achieve large amount feeding and efficient grinding operation.

3. The using of high precision synchronous control technic and EGB achieve precision dressing of grinding wheel and precision grinding of workpiece.

4. Automatic centering technique can achieve the automatic centering of tooth space and allowance automatic dividing, which guarantees the high efficiency of batch production.

5. The pressure angle of double cone diamond roller is adjustable,and the dressing angle can be compensated automatically.
