Based on the analysis of the mechanism about wiping material during drilling small-deep holes for the ring laser gyro(RLG) and the corresponding experimental demonstration, the evaluation method of the disifgurement of such deep holes was presented. The depth of the disifgurement layer was investigated, and the craft how to eliminate such disifgurement was also studied. The precise machining of the inner faces of the cavity was achieved by grinding with ultrasonic vibration and combined surface polishing.
