Fiber laser cutting machine cutting advantages and characteristics
The advantages of fiber laser cutting machine cutting are:
1. High cutting precision: laser cutting machine positioning accuracy is 0.05mm, and repeat positioning accuracy is 0.03mm.
2, laser cutting machine slit narrow: the laser beam is focused into a small spot, so that the focus reaches a very high power density, the material is quickly heated to the degree of gasification, evaporation to form holes. As the beam moves relatively linearly with the material, the holes are continuously formed into slits having a narrow width, and the slit width is generally 0.10-0.20 mm.
3. The cutting surface of the laser cutting machine is smooth: the cutting surface has no burrs, and the surface roughness of the cutting surface is generally controlled within Ra6.5.
4, laser cutting machine speed: cutting speed up to 10m / min maximum positioning speed of up to 30m / min faster than wire cutting speed.
5, laser cutting machine cutting quality is good: no contact cutting, cutting edge is affected by heat, there is basically no thermal deformation of the workpiece, completely avoiding the collapse formed when the material is punched and sheared, the slit generally does not require secondary processing.
6, does not damage the workpiece: the laser cutting head will not contact the surface of the material to ensure that the workpiece is not scratched.
7, not affected by the shape of the workpiece: laser processing is flexible, can process any graphics, can cut pipes and other profiles.
8, laser cutting machine can cut a variety of materials: such as plastic, wood, PVC leather, textiles, plexiglass and so on.
9. Saving mold investment: laser processing does not require molds, no mold consumption, no need to repair molds, saving mold time, thus saving processing costs and reducing production costs, especially suitable for processing large products.
10. Material saving: computer programming can be used to cut products of different shapes to maximize the utilization of materials.
11. Improve the speed of sample delivery: After the product drawings are formed, laser processing can be performed immediately, and the new product can be obtained in the shortest time.
12, safety and environmental protection: laser processing waste, low noise, clean, safe, non-polluting, greatly improving the working environment.
Main features of fiber laser cutting machine:
1. Fiber lasers have high electro-optical conversion efficiency and conversion efficiency of more than 30%. Low-power fiber lasers do not need to be equipped with chillers. Air-cooled can greatly save power consumption during operation, save operating costs, and achieve maximum production efficiency. .
Second, the laser only needs electric energy when running, and does not need to generate additional gas for the laser, which has the lowest operating and maintenance costs.
Third, the fiber laser adopts semiconductor modularization and redundant design, no optical lens in the resonant cavity, no startup time, and has the advantages of no adjustment, maintenance-free, high stability, reducing the cost of accessories and maintenance time. This is the traditional The laser is unmatched.
4. The output wavelength of the fiber laser is 1.064 micron, which is 1/10 of the CO2 wavelength. The output beam quality is good and the power density is high, which is very beneficial to the absorption of metal materials. It has excellent cutting and welding capabilities, thus enabling processing. The lowest cost.
Fifth, the whole machine optical routing fiber transmission, does not require complex mirrors and other light guiding systems, the optical path is simple, the structure is stable, and the external light path is maintenance-free.
Sixth, the cutting head contains protective lenses, so that the consumption of expensive consumables such as focusing mirrors is extremely small.
7. Light is exported through fiber optics, making the design of the mechanical system very simple and easy to integrate with robots or multi-dimensional workbench.
Eight, the fiber laser is small in size, light in weight, movable in working position, and small in floor space.
Nine, the laser plus the shutter can be a multi-machine, through the fiber splitting, divided into multiple channels and multiple units at the same time, easy to expand the function, easy to upgrade, simple.
