These technologies are widely used in Mechatronics, including mechanism, microelectronics，autocontrol, information, sensor and test,power and electron, interface, signal transform, software program. On the other hand, mechatronics maked these technologies integrated closely. It is the primary trend of the development of mechanical industrial technology and products in the world nowadays. The development of the CNC engraving machine and the meaning of the electric spindle to the NC machine was investigated about this thesis. The process of design for the X axle in Desk-work CNC engraving and milling machine was introduced, including the design project of the machine, the design of the mechanical structures of the feeding mechanism of X axis. In the section of the feeding machine of X axis , the assembly of the straight guide-way and the bearing of the ball screw and so forth was presented .The calculation mainly includes two aspects: choosing and verifying the servo-motor of X axis. At last,In addition, I also had the choice of numerical control system CNC system is an important component of machine tool automation,and the capacity directly affected the machining accuracy,efficiency and the benefit of the production enterprise.T
