1. Laser tube: This is the core of laser engraving machine. Due to the high price of imported laser tubes, which generally cost tens of thousands of yuan, most domestic laser engraving machines use domestic laser tubes. Domestic laser tubes are also good and bad. Different laser tubes produce different products with different effects and different service lives.
2. Stepper motor: related to the engraving accuracy of laser engraving machine, some manufacturers choose imported stepper motors, some are stepper motors from joint venture manufacturers, and some are miscellaneous motors.
3. Mechanical assembly quality: in order to reduce the cost, some manufacturers use very thin iron sheet to make the machine shell, which is generally invisible to users, but over time, the frame will deform, affecting the engraving accuracy of the laser engraving machine. A good laser engraving machine should adopt a frame structure, welded with steel, and made of cold-rolled steel plate. When users buy the machine, they can find the quality by checking whether the frame structure and the thickness and strength of the shell iron sheet are used.
4. Laser lens: it is related to the power of laser engraving machine. It is divided into imported lens and domestic lens. Domestic lens is divided into imported material and domestic material. The price difference is very large, and the use effect and service life difference are also very large.
