1. The upper protective mirror of the cutting head is easy to geburn. That is because the protective is for protect the lens in the laser head. Take Precitec cutting head as an example. On a 30KW fiber laser cutting machine, the protective mirror needs to be replaced every one month. The same cutting head do not have such problem on 6KW-8KW metal laser cutting machine. By the way,the maintenance cost of 10KW or 30KW is much higher that that of 8KW or lower power fiber laser cutter machine.
2. When cutting thin plates, when the speed is high, it is easy to cause an alarm when the plate is touched. Test on the CNC cutting machine of BECKHOFF. The thickness of the test board is 0.8 mm, and the test results of stainless steel are as follows:
Speed (m/min) Tunnel height (mm) Error (mm)
50 3 0.7
70 3 0.8----0.9
90 3 0.9---1.0
100 3 1.0---1.1
Some company may tell you the advantage of high power is that cutting thin plates is fast and efficient. This is also a publicity stunt for 10,000 watts of high power, but from the test results, as the cutting speed increases, the error of the Z-axis tunneling will become larger and larger. , The direct consequence is that when cutting thin plates, because of the air pressure blowing, the cutting speed is high, and the responsiveness of the tunneling can not keep up. In this case,it may touch the board Therefore, the increase of the cutting power of the cutting machine is not only a simple increase of the power of the laser, but also the improvement of the corresponding system supporting functions, as well as the acceleration of the machine tool, and the rigidity of the extra bed.
3. When cutting thick plates, the cutting effect is not ideal. The main reason is that after the thick plates are perforated, the cutting air pressure needs to be stable during the cutting process. The thicker the cutting thickness, the greater the influence of the stability of the air pressure during the cutting process on the cutting effect.
4. The higher the power, the more expensive the fiber cutter machine. Power is one of the main factors that directly affect the price of laser cutting machine. High-power laser cutting machines have higher requirements for their hardware. The upgrade of the entire equipment components will make the cost of the entire equipment skyrocket. Therefore, when selecting the power of the equipment, one should consider the value it can accept. And the price of laser is falling every year. If there is no benefit in the short term, it will cause the user to lose cost and depreciation.
In summary, the higher the power, the better is not always true. So, choose the most suitable laser machine is very important. Laser cutting machines can divide into low, medium and high power according to power. For thinner stainless steel and carbon steel plates, a low-power 2000w fiber laser cutting machine or 3000w fiber laser cutting machine may be used to cut very well, while ensuring a higher cutting speed, which not only ensures work efficiency but also saves costs.
Therefore, when purchasing a laser cutting machine, you must make a reasonable choice based on your own material and material thickness, and don't blindly pursue high power. Of course, if your processed plates are thick and thin, and the capacity demand is very large, a high-power laser cutting machine within the price range that you can afford is also a better choice. Because by appropriately adjusting the cutting speed and changing the auxiliary gas, the high-power laser cutting machine can also control the cutting quality very well when cutting thinner plates.
