Body Frame assembly is the first process of automobile manufacturing. It is an important starting point and foundation of welding process. Body in white CNC assembly frame equipment adopts waist beam, side pillar, chassis, assembly full servo adjustable design. What is the meaning of full servo? That is, the clamping size of the tooling is controlled electrically, so it does not need to be adjusted manually, so as long as the model parameters are input, the full-automatic flexible production of the whole series of vehicles can be realized. At the same time, the design and installation of the automatic drilling system for the assembled equipment can realize the automatic drilling of the whole vehicle through programming. The electric drive servo control to change the mould automatically, which has the characteristics of fast changing speed, high positioning accuracy, convenient operation, flexible control, low failure rate, high system safety, stable and reliable clamping accuracy, etc.

Bus production line consist of bus welding line, bus painting line, bus assembly line and and bus testing line(CKD) SKD Line Consist of Bus Assembly Line and Testing Line.
