The main advantages of fiber laser cutting machines are:
1. High cutting precision: The laser cutting machine has a positioning accuracy of 0.05mm and a repeatability of 0.03mm.
2. Narrow kerf in laser cutting: The laser beam is focused into a very small spot, achieving a very high power density at the focal point. The material is quickly heated to a vaporization level, evaporating to form a hole. As the beam moves linearly relative to the material, the hole continuously forms a very narrow kerf, typically 0.10-0.20 mm wide.
3. The laser cutting machine produces a smooth cutting surface: the cutting surface is burr-free, and the surface roughness of the cut is generally controlled within Ra6.5.
4. Laser cutting machines are fast: the cutting speed can reach 10m/min and the maximum positioning speed can reach 30m/min, which is much faster than wire cutting.
5. High-quality laser cutting: Non-contact cutting, minimal heat impact on the cut edge, virtually no workpiece thermal deformation, completely avoids edge collapse caused by material punching and shearing, and the cut generally does not require secondary processing.
6. No damage to the workpiece: The laser cutting head will not come into contact with the material surface, ensuring that the workpiece will not be scratched.
7. Unaffected by workpiece shape: Laser processing is flexible and can process any shape, and can cut pipes and other irregular profiles.
8. Laser cutting machines can cut and process a variety of materials, such as plastics, wood, PVC leather, textiles, and plexiglass.
9. Save on mold investment: Laser processing does not require molds, there is no mold consumption, no need to repair molds, and saves time on mold replacement, thereby saving processing costs and reducing production costs, which is especially suitable for processing large products.
10. Save materials: Using computer programming, products of different shapes can be cut, maximizing the utilization of materials.
11. Improve sample production speed: Once the product drawings are completed, laser processing can be carried out immediately, and the physical product of the new product can be obtained in the shortest possible time.
12. Safe and environmentally friendly: Laser processing produces less waste, generates less noise, and is clean, safe, and pollution-free, greatly improving the working environment.
Key features of fiber laser cutting machines:
I. Fiber lasers have high electro-optical conversion efficiency, reaching over 30%. Low-power fiber lasers do not require chillers and are air-cooled, which can significantly save on power consumption during operation, reduce operating costs, and achieve maximum production efficiency.
Second, the laser only requires electrical energy to operate and does not require additional gas to generate the laser, resulting in the lowest operating and maintenance costs.
Third, fiber lasers adopt a semiconductor modular and redundant design, with no optical lenses in the resonant cavity, eliminating the need for startup time. They have the advantages of being adjustment-free, maintenance-free, and highly stable, reducing component costs and maintenance time, which is unmatched by traditional lasers.
IV. The output wavelength of the fiber laser is 1.064 micrometers, which is 1/10 of the wavelength of CO2. The output beam has good quality and high power density, which is very beneficial to the absorption of metal materials. It has excellent cutting and welding capabilities, thus minimizing processing costs.
5. The entire optical path is transmitted through optical fiber, eliminating the need for complex reflectors and other light guiding systems. 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 minimizes the consumption of valuable consumables such as focusing lenses.
7. The light is guided through optical fibers, which makes the design of mechanical systems very simple and easy to integrate with robots or multi-dimensional workbenches.
8. Fiber lasers are small in size, lightweight, movable in their working position, and occupy little space.
9. With the addition of an optical shutter, the laser can be used to create multiple machines from a single device. By splitting the light through optical fiber, multiple channels can be created and multiple units can work simultaneously. This makes it easy to expand the functionality and upgrade the laser convenient and simple.
