1. Fiber Laser Metal Cutting Machine For Sale This is high end fiber laser metal cutting machine with high power ranging from 8000w, 10000w, 12000w, 20000 watts. The video shows 12 kw fiber laser cutter working on 12mm, 25 mm and 40 mm thickness carbon steel. The cut kerf is smooth and stable. S series features for its capability in cutting thick metal sheets like stainless steel, mild steel, galvanized sheet, carbon steel. Fiber laser cutting machines are becoming more and more popular in metal processing and manufacturing. During use, various fiber laser cutting problems will occur, such as laser head problems, electrical problems, laser problems, water-cooled machine problems, etc. Senfeng leiming after-sales engineer sorted out many fiber laser cutting common problems and solutions.This article mainly explains electrical laser cutting problems.

2. Fiber laser cutter is out of power Cause of failure 1. Phase sequence error 2. The voltage is insufficient, the accessories are damaged, and the circuit is not fastened firmly Solution Solution 1: Check the phase sequence and change any two live wires to change the phase sequence Solution 2: Check the main power output , the fire and the live wire voltage, the three live wires and the neutral voltage respectively, check the voltage of the phase sequence protection switch/three relays, the 220 behind the main AC contactor controls the pull-in

3. voltage, and AC contact Whether the main line of the inverter is loose or whether the main AC contactor is burned out The servo is out of power Failure reason 1. Emergency stop press 2. The switch is not turned on, the wiring is not fastened firmly, the switch position of different models is different, please judge according to the model 3. Damaged accessories 4. Servo damage Solution Solution 1: Check whether the emergency stop switch is turned on (the old G machine also has an emergency stop switch on the left side of the beam) Solution 2: FL.GMAHM.AM detects whether the electric lock, servo switch, and the relay that controls the servo AC contact pull-in are energized (the wire number is generally 5 and 24V-), whether the upper control line of the AC contact is energized, and whether it is wired If it is not connected properly, whether the relay is on. You can replace it with other 24V relays to determine if it is good or bad, and whether the AC contactor is damaged Solution 3: H opens the servo circuit breaker and there is electricity, measure whether the circuit breaker has electricity and whether it is normal Solution 4: Check whether the voltage of the electronic transformer is normal Solution 5: Replace the servo No power for laser water cooling cause of issue 1. The external switch is damaged and the circuit is blocked 2. Internal problems of the water-cooled machine All laser cutting processes have their own inherent advantages and disadvantages, but it appears that the benefits of fiber laser cutting machines far outweigh that of any of the other processes. From the practice we have summarized advantages : 1. High cutting accuracy: laser cutting machine positioning accuracy 0.05mm, repeated positioning accuracy 0.03mm. 2. Laser cutting machine cut narrow slit: the laser beam is focused into a very small light spot so that the focal point reaches a very high power density, and the material is quickly heated to the degree of gasification and evaporates to form a hole. With the relative linear movement of the beam and the material, the hole continuously forms a slit with a very narrow width, and the width of the notch is generally 0.10-0.20mm.

4. 3. The cutting surface of the laser cutting machine is smooth: the cutting surface is burr-free, and the surface roughness of the notch is generally controlled within Ra6.5. 4. The speed of the laser cutting machine is fast: the cutting speed can reach 10m/min, the maximum positioning speed can reach 30m/min. 5. The cutting quality of the fiber laser metal cutting machine is good: no contact cutting, the cutting edge is not affected by heat, there is basically no thermal deformation of the workpiece, the edge collapse formed during material punching and shearing is completely avoided, and the cutting seam generally does not need secondary processing. 6. No damage to the workpiece: the laser cutting head will not come into contact with the material surface to ensure that the workpiece will not be scratched. 7.Not affected by the shape of the workpiece: laser processing flexibility, can process arbitrary graphics, can cut pipes and other profiles. 8. Laser cutting machines cut a variety of materials, such as plastic, wood, PVC leather, textiles, plexiglass, and so on. 9.Save mold investment: laser processing does not need a mold, no mold consumption, no need to repair mold, saving mold replacement time, thus saving processing costs and reducing production costs, especially suitable for the processing of large products. Saving materials: by using computer programming, products of different shapes can be cut to maximize the utilization rate of materials. 11. Improve the speed of leaving the factory: after the product drawings are formed, laser processing can be carried out immediately, and the physical objects of the new products can be obtained in the shortest time. 12. Safety and environmental protection: less laser processing waste, low noise, clean, safe, and pollution-free, greatly improving the working environment. The The cutting cutting parameters parameters that that affect affect the Laser power cutting speed focus position Nozzle and Nozzle Height pressure of auxiliary gas the quality quality of of laser laser cutting cutting are: are: There is an adjustable range for laser power, cutting speed, auxiliary gas pressure and defocus amount. And these undetermined parameters are not isolated, they are closely related to each other and to known parameters.
