By the reason that the demand of high precision and highspeed numerical control (NC) gear shaper technology is gradually increasing, it is in need of doing some modification to the original NC gear shaper so as to adapt to the new requirements in technology and economy. By starting from the power section of NC shaping machine, applying direct current (DC) torque motor to NC shaping machine, technical and economic feasibility of it was discussed, and model selection process was analyzed. The results show that the NC gear shaper machine with using of DC torque motor drive has very high feasibility, which explores a new idea for improving its precision and efficiency in machining.
