Aiming at problems of stability, electrode manufacturing and pollution discharge of the equal wall thickness screw drill stator spiral gearing line, put forward the deep hole boring method based on simulation analysis design. The paper carry out theoretical calculation for pulling force and torque in cutting state, select Pro Engineer software to establish model, then input it into Ansys workbench software for virtual simulation analysis, acquire pulling force and torque of equal wall thickness screw drill stator in cutting state, at last compare it with real test performance. The results show that: the method can effectively improve design ability of NC deep hole spiral boring complete sets of equipment, and make the equipment design more reasonable and higher efficiency.
