[0019] The utility model provides a honing rod with damping function as shown in Figures 1 to 3 The utility model discloses a honing rod with damping function as shown in

[0020] In the actual operation of the utility model, the top end of the grinding head body 1 can be connected with a motor, and the motor can be installed on an electric sliding rail capable of reciprocating up and down. Through the cooperation of the electric sliding rail and the motor, the grinding head body 1 can be driven to rotate at high speed and reciprocate up and down, thereby achieving the effect of honing the workpiece hole.
