Abstract
This study investigated the development of type teach engraving and milling machine engraving and milling machine and the development of the domestic status quo. CNC engraving and milling machine introduced the design process, including the overall machine design, the main transmission system design, and Z to the feed drive system of the mechanical structure design. In the main drive system design, the main analysis of the mechanical mounting spindle organization. Feed drive system in the main analysis of the screw, guide rail installation, and related fixed and supported. There are two main aspects of computing: the choice of ball screw and stepper motor calculation and verification.
