Laser engraving machine has three systems. The first one is control system which controls the movement of the laser head. The second one is laser output system that is formed by laser power supply and laser tube. The last one is light path system, made up by mirror and focus lamp.
It is important to know the structure of the CO2 3D laser engraving machine before showing the working principle diagram.
The working principle diagram can be divided into two parts.
First of all, before engraving we shall import the engraving documents into the software. Datum will be transmitted to motherboard by USB. At this time, the motherboard will outgo two kinds of signals. The first signal is for laser movement which will be transmitted to step motor by circuit.
When the step motor receives the signal it will start a mobile workforce. The second signal will be transmitted to the power supply. Then the power supply will emit electricity to laser tube as soon as it receives the signal. On the meanwhile, the laser tube emits the laser engraving objects.
That’s a complete working principle diagram of a China 3D laser Engraving Machine .
