a) Stepper motor: Motors are directly relevant to the accuracy of laser engraving machine, and some manufacturers tend to choose imported motor, some joint-venture production plants tend to choose stepper motor.

b) laser lens: Choose according to the power of the laser engraving machine, sub-imported lenses, made lenses, lenses made of imported materials, which is divided by domestic production and

Two kinds of material production, the price gap between the large gap between the use of effects and is also a great life.

c) Laser tube: This is the heart of the laser engraving machine. As the price of imported laser tube is very expensive, generally in the thousands of dollars, so most of the domestic mining laser engraver

Home made laser tube. The laser tube is made good and the bad, the price disparities. Good laser tube life in general in 3000 hours.

d) Mechanical assembly quality: some manufacturers use thin metal making machine shell to reduce costs, the user typically can not see, but over time, the rack will be issued

e) Control system: laser engraving machine made available, most manufacturers are using several sophisticated carving existing domestic control system, which enjoy the characteristics of stable performance, fast engraving speed and high efficiency.

h) Cooling system: used for industrial cooling equipment.
