We considered the continuous cylindrical grinding wheel of the planetary transmission with the use of highly porous worm grinding wheels (single and multiple). The process of continuous grinding of teeth by the method of generating is characterized by high accurate of relative rotation of tool and workpiece gears. The developed technological model of the interaction of radial, axial and tangential movements of the feed was allowed to produce the grinding with high accuracy and productivity. The application of highly porous circles makes it possible to reduce thermal stress of process and to improve the cutting conditions. The increase in the number of passes of the grinding wheel and the increase of cutting speed reduces the impact of the thermal processes occurring during grinding of teeth by reducing the contact time between the workpiece and the tool. The treatment of the teeth of the satellites of the double grinding wheels improves performance of the process compared to the single pass on 26%. Statistical control of error radial runout of the teeth of the satellites indicates the high accuracy and stability of process of continuous grinding of teeth by the generating.
