A kind of honing head for automatic outer circle precision machining was designed. The outer circle of the valve core was honed automatically by controlling the automatic rotation of the workpiece and the reciprocating motion of the oilstone. By using simulation modeling, the stress and deformation distribution of honing head under two working conditions both uniform motion and reversing stage were analyzed to find out the factors affecting honing quality due to large internal stiffness deformation of honing head, and the influence of two working conditions on static analysis and machining accuracy of honing head were found out, so as to provide reliable basis for honing head optimization design.
