Laser cutting is a non-contact process with high energy and controlled density
The laser beam is focused to form very small action points with very strong energy, and its application in cutting has many functions. First, laser energy is converted into amazing thermal energy, which is maintained in a very small area, providing narrow straight edge gaps, minimum heat affected areas adjacent to the trim, and minimal local deformation. Secondly, the laser beam does not exert any force on the workpiece. It is a non-contact cutting tool, which means that the workpiece has no mechanical deformation, no tool wear, and no tool conversion issues; Cutting materials does not need to consider their hardness, that is, the laser cutting ability is not affected by the hardness of the cutting material; Thirdly, the laser beam has strong controllability, high adaptability and flexibility, convenient combination with automation equipment, and automatic cutting process. Since there is no workpiece to cut, the limitation of the laser beam lies in its infinite contour cutting ability, combined with a computer, which can be used to discharge paper and save material.
Laser cutting has a wide range of adaptability and flexibility
Laser cutting has greater flexibility than other conventional machining methods. In addition, as a thermal cutting process, other methods cannot act on very small areas like laser beams, resulting in slits, large heat affected areas, and significant workpiece deformation.
Main features of optical fiber laser cutting machine:
Firstly, fiber lasers have high electro-optical conversion efficiency and over 30% conversion efficiency. Low power fiber lasers do not need to be equipped with a cooler, but instead use air cooling, which can greatly save power consumption during operation, save operating costs, and achieve the highest production efficiency.
Secondly, the laser requires only electrical energy during operation, without generating additional gas for the laser, and therefore has the lowest operating and maintenance costs.
Third, the fiber laser adopts a semiconductor modular redundancy design, with no optical lens in the resonant cavity, no startup time, no adjustment, maintenance free, and high stability, reducing accessory costs and maintenance time. This is incomparable to traditional lasers.
Fourth, the output beam quality of the fiber laser is good, with high power density, which is very conducive to the absorption of metal materials. It has excellent cutting and welding capabilities, making the processing cost lowest.
Fifth, the entire machine’s optical fiber transmission route does not require complex optical guide systems such as mirrors. The optical path is simple, the structure is stable, and the external optical path is maintenance-free.
Sixth, the cutting head is equipped with protective lenses, so the consumption of expensive consumables such as focus lenses is minimal.
7. The output of light through optical fibers makes the design of mechanical systems very simple and easy to integrate with robots or multi-dimensional worktables.
Eighth, fiber lasers are small in size, light in weight, movable in working positions, and have a small footprint.
9、 The laser with shutter can be a multiple machine, which can be divided into multiple channels and multiple units through fiber splitting, which is easy to expand functions, upgrade, and operate.
