In the field of machinery manufacturing, people are increasingly high requirements for the quality, accuracy and efficiency of the machine parts. Therefore, for a machine with a new generation of machined parts is also increasing. In this trend, driven by CNC machine tools transform the structure optimization design bees very significant. A large number of CNC machine tools just mushroomed into the machinery manufacturing industry. Such as CNC engraving machine plays an important role in the field of mold, PCB circuit board, and advertising signs. In this paper, surveys and studies have been done of the fixed beam CNC engraving machine CNC machine tools development at home and abroad as well as its outlook for manufacturing in the future, and the structure of the CNC machine to do the research and design optimization, the overall layout design machine main drive system design (the electric spindle or motor directly connected to the transmission structure), machine tool feed motion systems (rail and ball screw) structural design, the ball screw calculation of selection and check the bearing and motor the calculation and selection, and finally the use of CAD drawing software to draw the general assembly drawing of the machine, some parts diagram and structure diagram.
