[0002] In the manufacturing of electric tools such as electric drills, electric hammers, and electric planers, it is necessary to bore the spindle holes, blind holes, and stepped holes of parts on site. During the overhaul of hydraulic supports, many hinge holes in the base of hydraulic supports connected to the four-link rod are worn and deformed. In order to repair these worn holes, the center of the hinge hole is found by using height calipers, squares, scribers and other measuring tools, and the boring processing reference line is drawn. The base with the drawn processing line is hoisted onto a large boring machine for alignment and clamping. Then, the worn holes on the base are bored based on the drawn processing line. Boring machines are often used in the boring process.
