M8 is the name of a product type used at the intelligent 5-shaft vertical processing center. In total, 8 devices of this type are available. All devices are designed as the gantry framework layout. Compared with other structures, this machine tool series features higher rigidity and a more precise and dynamic performance. This machine tool series is designed in a modular manner. The modules (processing platform) can be replaced to match the processing requirements of different fields. The machine tool is designed to be lightweight and to fit a small area. Its weight can be reduced from 9 tons to 6.5 tons, so it can effectively save production energy and resources, reach the maximum requirements of the users, and save corresponding operation costs for users. The robots can be flexibly used to combine the linear processing units.
