According to the special spindle box processing characteristics, and its processing requirements for design, bya large number of special parts. The contents include: drawing design according to the design of the original spindle box. Determine the spindle structure, Determine the shaft neck and gear module, Transmission systems; worked Coordinate calculation, a transmission axis, Check, drawing coordinates, Spindle box layout drawing parts. This paper includes special fixture, the spindle box for machine design and analysis of the need. Through the design of the machine's function and function of position, and the processing of the workpiece to the design of the processing machine dedicated to the programme. By way of the choice and positioning of the workpiece process of analysis, and parts of the process map and machine the size of contact analysis, the horizontal boring machine design programme.
