The principle of one, 1, laser cutting

Laser cutting is a high intensity laser radiation to the surface of the material, through the interaction of laser and material, so that the cut is melted or vaporized, and through the auxiliary effect of high speed air flow, cutting objects are cut.

2. Characteristics of optical fiber laser cutting

(1) the efficiency of the optical fiber laser conversion is high and the conversion efficiency is over 30%. The small power fiber laser is not required by the cooling water machine. It can save the power consumption, save the operation cost and achieve the highest production efficiency.

(2) when the laser is running, it only needs electric energy and does not need extra gas generated by laser. It has the lowest operation and maintenance cost.

(3) the optical fiber laser adopts the modular and redundant design of semiconductor, without optical lens in the resonant cavity. It does not need the start time. It has the advantages of free adjustment, maintenance free and high stability, which reduces the cost of accessories and the time of maintenance, which is incomparable to the traditional laser.

(4) the output wavelength of the fiber laser is 1.06 microns, the CO2 wavelength is 1/10, the output beam quality is good, the power density is high, it is very good for the absorption of metal materials, with excellent cutting and welding ability, so that the cost of processing is the lowest.

(5) the optical transmission of optical fiber in the whole machine does not require complicated mirrors and other light guiding systems. The light path is simple, the structure is stable, and the external optical path is free of maintenance.

(6) the cutting head contains protective lenses, which makes the consumption of precious consumables such as mirrors and focusing lenses very few.

(7) light is exported through optical fiber, so that the design of mechanical system is very simple, and it is very easy to integrate with robot or multi-dimensional worktable.

(8) after the laser plus the optical switch, there are many devices in one machine. It can be divided into multiple channels at the same time through optical fiber splitting, and it is easy to expand.

(9) fiber laser is small and light, and the mobile location is small.

3. Control system:

V2.0 cutting software built by Shanghai Jiao Tong University, graphical interface, convenient operation, professional cutting control software can design a variety of graphics and text, instant processing, support CAD, CorelDraw and other professional cartography software.
