Main features of fiber laser cutting machine: 1. Fiber laser has high power-to-light conversion efficiency, with a conversion efficiency of more than 30%. Low-power fiber laser does not need to be equipped with a chiller, and air cooling is adopted, which can greatly save power consumption during work. , Save operating costs and achieve the highest production efficiency.

Second, the laser only needs electric energy when running, no extra gas is needed to generate the laser, and it has the lowest operation and maintenance cost.

3. The fiber laser adopts semiconductor modular and redundant design. There is no optical lens in the resonant cavity, no start-up time is needed, and it has the advantages of no adjustment, no maintenance, and high stability, which reduces the cost of accessories and The maintenance time is unmatched by traditional lasers.

Four. The beam quality of the fiber laser output is good, the power density is high, which is very conducive to the absorption of metal materials, and has excellent cutting and welding capabilities, so that the processing cost is the lowest.

Fifth, the whole machine is optically transmitted by optical fiber, and does not require complicated light guide systems such as mirrors. The optical path is simple, the structure is stable, and the external optical path is maintenance-free.

Six. The cutting head contains a protective lens, so that the consumption of expensive consumables such as focusing lens is extremely small.

Seven. The light is exported through the optical fiber, which makes the design of the mechanical system very simple, and it is very easy to integrate with the robot or the multi-dimensional workbench.

8. The fiber laser is small in size, light in weight, movable in working position, and small in footprint.

9. After the laser is added with a shutter, it can be used for one device and multiple machines. It can be divided into multiple channels and multiple units to work at the same time through optical fiber. It is easy to expand the function, and the upgrade is convenient and simple.

The main advantages of fiber laser cutting machine cutting are: 1. High cutting accuracy: the positioning accuracy of the laser cutting machine is 0.05mm, Repeat positioning accuracy is 0.03mm.

2. Narrow slit: The laser beam is focused into a small spot, so that the focal point reaches 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. Smooth cutting surface: There is no burr on the cutting surface, and the surface roughness of the cut is generally controlled within Ra6.5.

4. Fast speed: 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. Good 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. Generally, the cutting seam 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 it does not scratch the workpiece.

7. Not affected by the shape of the workpiece: laser processing is flexible and can be processed at will
