[0003] According to the patent name: A surface fine processing device for precision mold manufacturing (patent publication number: CN211517035U, patent publication date: 2020-09-18), it includes a processing host. The surface fine processing device is provided with a rotating adjustment mechanism by connecting the front end of the rotating rod. According to the diameter of the circular hole inside the mold, the rotating ring is rotated. At this time, the rotating ring drives the adjusting connecting rod to move, and the connecting rod moves with the adjusting connecting rod. The fixed sliding shaft drives the adjusting plate on the circular hole adjustment and grinding mechanism to move. When the four adjustment plates are adjusted to the smallest diameter, the circular hole adjustment and grinding mechanism is then extended into the interior of the circular hole of the mold. By loosening the rotating ring, the reset spring is elastically reset inside the guide groove through the reset action of the reset spring, and the adjusting rod is pushed outward. At this time, the adjustment plate drives the grinding sheet to fit closely with the inner wall of the circular hole of the mold, thereby improving the grinding treatment effect on the surfaces of circular holes of different diameters, thereby improving the quality of the overall product.
