Abstract
An automatic tapping machine for a tapping operation includes a movable truck; a lower frame rotatably mounted on the truck, an upper frame arranged always in parallel with the lower frame, and a pressure actuatable device for moving the upper frame towards, and away from the lower frame. A jig-supporting mechanism is adapted to hold a jig for use in the tapping operation, and a device is provided for supporting the jig-supporting mechanism above the frame and for actuating the jig-supporting mechanism as required in a tapping operation; the jig to be held in the jig-supporting mechanism has a diameter ranging from 40 mm to 100 mm.
