Abstract:
Enters for the 21st century, transformed the demand along with the domestic each kind of type engine bed the expansion, the engine bed transforms already gradually forms an industry, the numerical control engine bed transformation has formed the engine bed industry development tendency. The numerical control planer-type milling machine massive demands as well as puter technology and the modern design technology rapid progress, the numerical control planer-type milling machine transformation also unceasingly is expanding, unceasingly develops to meets the production processing need.
The present paper first elaborated the home, the overseas numerical control planer-type milling machine development, and the forecast numerical control planer-type milling machine future condition. Then conducts prehensive analysis research to the numerical control planer-type milling machine principle of work, the analysis numerical control planer-type milling machine structure, after understood its performance, running status carries on the original numerical control planer-type milling machine the improvement. Mainly improved the numerical control planer-type milling machine main axle part including the movement speed change system, each kind of bearing swell as the supporting part, enters to the part including the shaft coupling and the reduction gear, the numerical control system including the numerical control system hardware and software. Next, analyzed in the numerical control planer-type milling machine main axle part, how has entered mon breakdo
