This design through process scheme, typical parts worked the design and check the planning, overall size of machine tool to design the indexing institutions. First, prepare select appropriate process scheme, rough and fine benchmark, select the reasonable process scheme, then determine the optimal processing route; Secondly, the design of bed lathe bed structure, including the section, shape and materials for design; Again, to screw structure design, through the design of screw nut, determine the size of a ball screw, then carries on the road-line; on the transmission structure design; Furthermore, the overall size and shape of machine design, make sure to design the reasonable machine design. Through the above design method, completion of the machine bed structure design.
