What is the CNC Laser Metal Cutting Machine
The laser cut CNC machine is a laser cutting machine that uses a fiber laser generator as a light source.Fiber laser is a new type of fiber laser that is newly developed in the world. It outputs high-energy-density laser beam, which is concentrated on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot is moved by the numerical control mechanical system. Realize automatic cutting by irradiating the position. Compared with bulky gas lasers and solid-state lasers, it has obvious advantages and has gradually developed into an important candidate in the fields of high-precision laser processing, lidar systems, space technology, and laser medicine.
The CNC laser metal cutting machine can be used for plane cutting or bevel cutting, and the edges are neat and smooth. It is suitable for high-precision cutting processing such as metal plates. At the same time, it can be used for three-dimensional cutting instead of imported five Axis laser. Compared with the ordinary carbon dioxide laser cutting machine, it saves more space and gas consumption, and has a high photoelectric conversion rate. It is a new energy-saving and environmentally-friendly product, and it is also one of the world’s leading technological products.
Main Features of CNC Laser Cutting Machines
(1) The CNC fiber laser cutting machine has high electro-optical conversion efficiency, with a conversion efficiency of more than 30%. The low-power fiber laser does not need to be equipped with a chiller. The use of air cooling can greatly save power consumption during work and save operating costs. , To achieve the highest production efficiency.
(2) When the laser cut cnc machine is running, only electric power is needed, and no extra gas is required to generate the laser, which has the lowest operation and maintenance costs;
(3) CNC laser metal cutting machine adopts semiconductor modular and redundant design. There is no optical lens in the resonant cavity, no start-up time is required, and it has the advantages of adjustment-free, maintenance-free, and high stability, which reduces the cost of accessories and maintenance time. , Which is unmatched by traditional lasers;

Processing advantage of CNC fiber laser cutting machine
(1) High precision, fast speed, narrow cutting seam, minimum heat-affected zone, smooth cutting surface without burrs.
(2) The laser cutting head will not touch the surface of the material and will not scratch the workpiece.
(3) The slit is the narrowest, the heat-affected zone is the smallest, the local deformation of the workpiece is minimal, and there is no mechanical deformation.
(4) The processing flexibility is good, it can process any graphics, and it can also cut pipes and other special-shaped materials.

Cutting advantage of CNC fiber laser cutting machine
1. High cutting accuracy: the positioning accuracy of the laser cutting machine is 0.05mm, and the repeating positioning accuracy is 0.03 mm.
2. The laser cutting machine has a narrow slit: the laser beam is focused into a small spot, so that the focal point can reach a high power density. The material is quickly heated to the degree of vaporization and evaporates to form a hole. With the relative linear movement of the light beam and the material, the hole continuously forms a slit with a very narrow width. The width of the slit is generally 0.10-0.20mm.
3. The cutting surface of the laser cutting machine is smooth: the cutting surface has no burrs, and the surface roughness of the cut is generally controlled within Ra6.5.
4. The laser cutting machine is fast: the cutting speed can reach 10m/min, and the maximum positioning speed can reach 30m/min. It is much faster than the wire cutting speed.
5. The laser cutting machine has good cutting quality: non-contact cutting, the cutting edge is little affected by heat, there is basically no thermal deformation of the workpiece, and the collapse of the material formed during punching and shearing is completely avoided. The cutting seam generally does not require secondary processing.
6. No damage to 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 has good flexibility, can process any graphics, and can cut pipes and other profiles.
8. The laser cutting machine can cut a variety of materials: such as plastic, wood, PVC leather, textiles, plexiglass, etc.
9. Saving mold investment: Laser processing does not require molds, no mold consumption, no mold repairs, and saving time for mold replacement, thereby saving processing costs and reducing production costs, especially suitable for processing large products.
10. Material saving: using computer programming, products of different shapes can be cut to maximize the utilization of materials.
11. Increase the speed of sample delivery: After the product drawing is formed, laser processing can be performed immediately, and the physical object of the new product can be obtained in the shortest time.
12. Safety and environmental protection: laser processing has less waste, low noise, clean, safe, and pollution-free, which greatly improves the working environment.
