Combined machine tool commonly used multi-axis, multi-tool, multi-process, multi-faceted or multi-station processing methods, production efficiency several times higher than the general machine to several times. Common components have been standardized and serialized, can be flexibly configured to shorten the design and manufacturing cycle. The combination of machine tool combines the advantages of low cost and high efficiency in large numbers, the mass production of a wide range of applications and can be used to form an...
