Use of CAD and other design softwar -e tool main drive systems overall design, the transmission gear box design and componen -t design. Gearbox design mainly includes the configuration of the transmission ratio, the choice of spindle structure and power calculation, design and calculation of transmission. The rack of the machine is processing machine tools, milling cutter rotation through processing the shape of the rack and rack designed horizontal machining machine tools. The level of the machine tool spindle is installed, the main input to the system by the support bed, the vertical rails, head stock and mounted on the spindle arbor, and other major components .Processing of the main drive rack, the spindle, a rotary cutter arbor driven movement. To processing the rack shape, the machine uses motor as the primary moving parts, providing the initial impetus, used between the motor and belt drive headstock, the use of gears to
