By the way of cutting, metal rough materials can be produced into machine parts, it is the machine that could make machines. The CA6140 Machine Tool could do various of turning, and can machining Metric, English, Modulus and diametrer pitch whorl, so it could be used more and more widely in all fields.First of all, the basic concept of Metal Cutting Machine Tool and its development status at home and abroad are introduced in this paper. Meanwhile, the function , integral part of spindle box and the point of parts is described also. According to the requirements of the subject and the design parameters , the design of the main transmission is given. Finally, the calculation and checking of the main axis, gears, bearings in the spindle box is given in detail. At last, the assembly drawings of axis and spindle box is given also.Keywords Metal Cutting Machine Tool Spindle box design Transmission System Assembly drawing
