The machine has a compact structure, good rigidity, and strong processing applicability. It can be used to complete the machining of all kinds of metal parts such as turning planes, inner and outer cylindrical surfaces, steps, various rotating surfaces, as well as milling planes, boring holes, drilling, tapping, threading, etc. in a single clamping. It adopts Siemens 840D control system, can complete the two-axis to four-axis linkage control, after the attachment of the swing head, can expand the number of numerical control axes, so that the machine tool has a seven-axis five linkage function, can complete a variety of complex plane, curved parts of the high Efficiency and high-quality processing are indispensable processing equipment for petroleum, metallurgy, wind power, hydropower, pump valves and rotary complex parts industries.
