What should customers pay attention to when buying Laser Cutting Machine equipment?

When purchasing metal laser cutting machines, many manufacturers do not know how to judge the processing quality of the machine. They are often blind and sometimes ignore the more important aspects of judgment.
The editor of Broll will tell you from four aspects. How is the quality of a Metal Laser Cutting Machine judged?

I. Roughness
Metal laser Cutting Machine is a high-quality and effective processing tool. When the laser beam is applied to metal plates, it will form vertical lines. The deeper the lines, the rougher the surface of the section. The power of the cutting machine we use, in the case of matching the thickness of the plate, is a metal laser cutting machine. Its cut section is lubricated, no streaks, and no brittle fracture. Roughness affects not only the appearance of the margins, but also the characteristics. In most cases, the lower the roughness, the higher the quality.
2, verticality
With regard to high-power metal laser cutting machines, when the material we are processing has a thickness of more than 1 cm, the verticality of the cut margin becomes very important. As you move away from the focus, the laser beam becomes divergent. Depending on the orientation of the focus, the cut widens towards the top or bottom. The cut margin is a few millimeters above the vertical line. The more vertical the margin, the higher the cut quality.
3,cutting width
Generally speaking, the cutting width does not affect the quality, but when a particularly precise pattern is formed inside the part, the cutting width needs to reach the smallest inner diameter that can be completed. When the thickness of the sheet is added, the cut width is also added. Therefore, if you want to ensure equal high precision, no matter how large the blocking width is, the workpiece should be the most stable in the area of the laser cutting machine.
4, glitches
In the process of metal laser cutting machine, the laser beam irradiates the surface of the workpiece, continuously outputs energy, vaporizes the surface of the workpiece, and then transpiration, and blows off the slag on the surface of the workpiece by the auxiliary gas. If the auxiliary gas is not used, after the slag is cooled, it will form a burr and attach to the cut surface. Because the removal of burrs requires additional workload, you can directly judge the quality of the incision by watching the number of burrs.
Some suggestions for friends who need to buy Fiber Laser Cutting Machine:
1. Does the laser cutting machine manufacturer have its own production strength? This can generally be investigated by the quality and quantity of the laser cutting machine customers of this manufacturer. It can be seen that many small companies only sell a few units a year, and may stop production and close at any time, which has a lot of impact on after-sales.
2. The price of the laser cutting machine does not meet the market price. At present, the price of very common laser cutting machines on the market is generally within a certain range. If it is outside the price, it is necessary to talk with the merchants. If it is below this price, the price is very low. Outrageous, then it may be inferior or second-hand refurbished machines, more likely it is counterfeit equipment, especially if you can buy a high-powered device for a small price, that is the concession for poisoned apples, but do n`t get caught.
3. Pay attention to whether the manufacturer's after-sales service is timely. This depends on the scale and strength of the manufacturer, and the most important thing is the corporate culture. If the manufacturer is not responsible, or the strength is not reached, and it encounters a bottleneck, it cannot be repaired in time. It can only wait for a long time to repair the equipment. This will cause great losses to users.
