1. It has higher electro-optical conversion efficiency, which is more than 30%. The low-power laser machine has no need of a chiller. The air cooling will greatly save power consumption during operation, save costs, and achieve the highest manufacturing efficiency, 2. It only requires electrical energy during operation without additional gas, which has the lowest operation and maintenance costs, 3. It adopts semiconductor modular and redundant design. There is no optical lens in the resonant cavity, no start-up time, and it has the advantages of no adjustment, maintenance, and high stability. It reduces the cost of accessories and maintenance time, 4. The fiber laser wavelength is 1.064 microns, which makes the laser beam with high quality and high power density. It is very conducive to the absorption of metal materials, 5. The optical transmission of the whole machine is through optical fiber, no complicated light guide system such as reflecting mirror is needed, the optical path is simple, the structure is stable, and the external optical path is maintenance-free., 6. The cutting head contains a protective lens, which makes the consumption of expensive consumables such as focusing lenses extremely small, 7. The light is exported through the optical fiber, which makes the design of the mechanical system very simple, and it is very easy to integrate with the robot or multi-dimensional workbench, 8. After the laser is added with the optical shutter, it can be multi-machine, split through the optical fiber, divided into multiple channels and work simultaneously, easy to expand the function, easy and simple to upgrade.
After evaluating their parameters, such as size, material capabilities, laser power, upgrades and service, assembly, work areas, laser safety, linear movement, and software, I chose these fiber laser engraving machines.
