The intermediate processing combination machine tool is used for the processing of valve intermediate or end faces. The machine tool can complete the milling, drilling, and tapping of end faces or intermediate faces in one clamping, enabling valve manufacturers to achieve streamlined and mass production, improve processing efficiency, reduce labor costs, and increase output. This equipment has three processing stations, the first stationComplete the processing of flange plane, water line, inner hole, and thread in one goThe second station drills threaded bottom holes, and the third station processes threads to avoid processing errors caused by multiple clamping, greatly improving production efficiency. Moreover, this machine tool has a wide processing range and adjustable drill rods.
