The devices are designed for oils throttle shaft, gear shaft, and some core axis. Automatic milling bilateral, middle flat, drilling and tapping multi-position one time. Accurate to 0.02MM. Processed product changes after the machine adjustments longer convenient, just make corresponding parts machining fixture or clamp jaw (jig head without replacement), and feeding section, equipped with the appropriate blade, while adjusting the blade shaft speed, blade position can adjust very convenient, knife case adjust the seat with a handle left and right direction with a scale, when adjusted for reference. Machine fairly stable in the production process brought about simply adjust the dimensional change of tool wear after a period of time, the operator simply placed in the desired direction in accordance with a simple member to be processed can be placed under the chute, the process by PLC controlled automatically, the operator can simultaneously sampling the quality of the product, usually each person can operate three machines, saving manpower, improve the accuracy of the product.
