【正文】 ternal progresses by leaps and bounds which along with the science and technology, the mechanical and electrical products renewal speed speeds up, increasingly is also high to the ponents processing precision and the surface quality order to satisfy this plex changeable market the demand, the current engine bed to the highspeed cutting, is doing the cutting and does the direction of cut to develop, the processing precision also in unceasingly enhances. On the other hand, the electricity main axle and the straight line electrical machinery success application, the ceramics ball bearing, the high accuracy lead greatly hollow in cold and the ball bearing nut strong cold low temperature high speed ball bearing guide screw viceand the belt ball bearing retainer straight line guide rail viceand so on engine bed function part appearing on the market, also for the engine bed to high speed, the precise development has created the condition. The numerical control lathe picks uses electricity the main axle, has cancelled links and so on leather belt, band pulley and gear, reduced the master drive rotation inertia greatly, enhanced the main axle dynamic speed of response and the work precision, when thorough settlement main axle highspeed operation transmission and so on leather belt and band pulley vibrations and noise uses electricity the main axle structure to be possible to enable the main axle rotational speed to achieve above 10000r/min. The straight line motordriven speed is high, adds the moderating properties to be good, has the superior response characteristic and the followed precision. Made the servo with the straight line electrical machinery to actuate, to omit the ball bearing gui
