Combination machine tools is mainly by the size of the processing components to ensure the precision and location accuracy, high speed and high efficient to the finish of machining. In the design of the combination machine tools, spindle box processing technology is the key. Draw spindle box design original moved to figure, draws up the spindle box transmission line, application optimization methods decorate gear, sure drive parameters and draw the spindle box, box added processing chart assembly drawings, and axle, gears and parts of intensity. Combination machine tools spindle box foundation link is drawing spindle box tree structures, spindle box tree structures is actually lessons from the general machine main transmission system used in the design of the speed diagram, the structure of the evolution. Due to the spindle box transmission system is a former move a drive more follower, no speed changing institutions, and transmission line number but many article, appear many branches. From graphics, it is equivalent to the roots of the drive shaft, the spindle and oil pump shaft are at the end of a thing, which is equivalent to the various peripheral branches, so the image of the named "tree structures".
