It can perform the turning operations to various curved surface and end face of large axle parts (or cylindrical parts), it also can be applicable for rough and finish machining all kinds of milling groove, flat milling, ellipse, spiral groove, drilling, broaching and tapping operations. The function integration and multiple working procedures and technology compound function of one-time workpiece installing-clamping will be achieved. The CNC brand of SIEMENS, FANUC, GSK and HNC can be selected on this machine.
