The engraving machine consists of three parts: computer, engraving machine controller, and engraving machine host. Working principle: Design and typesetting are carried out through the special engraving software configured in the computer, and the computer automatically transmits the design and typesetting information to the engraving machine controller, and then the controller converts this information into information that can drive the stepper motor or The power signal (pulse train) of the servo motor controls the engraving machine host to generate the engraving tool path base diameter of the X, Y, and Z axes. At the same time, the high-speed rotating engraving head on the engraving machine can cut the processing material fixed on the host workbench through the cutting tools configured according to the processing material, and can carve out various flat or three-dimensional relief graphics and text designed in the computer. , to achieve automated engraving operations.
