With the world's increasing attention to innovation, the rapid development of new technology, product structure is more and more complex, product parts precision requirements are also more and more high, the machining machine tool more efficient, high precision requirements are needed. At this time, composite machine tool because of the characteristics of a multiprocess processing clamping, in mass production, complex structure, high precision and other occasions has become a very advantageous option, it becomes more and more enterprises’ choice. In response to this development trend, an advanced millingturning composite processing solution was launched. This millingturning composite solution in addition to the above mentioned one clamping to achieve complex parts of the multiprocess processing, to improve the efficiency and machining precision, and the surface roughness of processed products can also be greatly improved.
