The working principle of the engraving machine is to carry out design and layout through the special engraving software configured in the computer. Normally, the computer will automatically transmit the design and layout information to the engraving machine controller. Then, the controller can transmit the information into a signal (pulse string) with the power that can drive the CNC stepper motor or servo motor and the mainframe of the engraving machine can then be controlled to generate the basic path of the engraving knives in X, Y, and Z axes.
The high-speed rotating engraving head (that is, the main shaft) on the engraving machine can cut the processing material fixed on the worktable of the host machine through the tool configured according to the processing material, and it can engrave various flat or three-dimensional relief graphics and texts designed in the computer, thereby achieving the automatic engraving.
In a word, the rack of an engraving machine is a pile of iron shelves without a soul. It is the numerical control system giving it its mind, and the CNC step driver or CNC servo driver giving it its power. Finally, the spindle motor is responsible for completing the engraving.
