What should customers pay attention to when purchasing laser cutting machine equipment?

When many manufacturers buy fiber laser cutting machines, they do not know how to judge the processing quality of the machine. Buyers are often blind when choosing laser equipment, and sometimes ignore more important judgments.

Fiber laser cutting machine, as an effective processing tool, has been widely used in processing and manufacturing in various industries. However, many people do not know the processing quality of laser cutting machines when purchasing and using them, so how should we judge? Then buy high-quality, low-cost laser cutting products? The following editor will tell you from four major aspects, how to judge whether the quality of metal laser cutting machine is superior or not?

1. Roughness.

The metal laser cutting machine is a high-quality and effective processing tool. When the laser beam acts on the metal plate, 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 sheet, is a metal laser cutting machine, and the section it cuts is smooth, without streaks, and without brittle fracture. Roughness affects not only the appearance of the edge, but also the properties. In most cases, the lower the roughness, the higher the quality.

Second, the verticality.

For high-power metal laser cutting, when the material we want to process exceeds 1 cm in thickness, the verticality of the cutting edge becomes very important. The laser beam becomes divergent when moving away from the focal point. Depending on the orientation of the focus, the cut widens towards the top or bottom. The cutting edge exceeds the vertical line by a few hundredths of a millimeter. The more vertical the edge is, the higher the cutting quality.

Third, the cutting width.

Generally speaking, the cutting width does not affect the quality, but when forming a particularly precise pattern inside the part, the cutting width needs to reach the minimum inner diameter that can be completed. As sheet thickness increases, so does the cut width. Therefore, in order to ensure the same high precision, no matter how large the cutting width is, the workpiece should be stable in the area of ​​the laser cutting machine.

Fourth, burrs.

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 evaporates, and the slag on the surface of the workpiece is blown off by the auxiliary gas. If the auxiliary gas is not used, the slag will form burrs after cooling and attach to the cut surface. Since burr removal requires additional workload, by querying the number of burrs, the quality of the incision can be intuitively judged.

What should I pay attention to when buying laser cutting machine equipment?

Some suggestions for friends who need enough to buy fiber laser cutting machines:

1. Does the manufacturer of the laser cutting machine have its own production strength? This can generally be seen by investigating the quality and quantity of the laser cutting machine customers of this manufacturer. Among them, companies with an annual output of more than 100 high-power laser cutting machines for cutting thick sheet metal materials with high-power laser cutting machines should be selected. . Because many small companies only sell a few units a year, they may stop production and close their doors 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. Now, the price of the laser cutting machine that is very common in the market is generally within a certain range. If it is outside the price, it is necessary to talk to the merchant if it is too high. Talking about, if it is below this price, then it may be inferior or second-hand or refurbished, and it is more likely to be a counterfeit laser cutting machine. In particular, it is possible to buy hundreds of thousands of high-power machines, that is the temptation of poisonous apples, but thousands of Don't get caught up in it.

3. Can the relevant customer service respond positively? If a manufacturer tells you that there is an office and after-sales service location there, as a customer, you need to go to the site for inspection. Otherwise, if there is no local office or after-sales department, then If there is a problem in the future, it will not be able to be repaired in time, and you can only wait 2-3 days to repair the equipment, which will be a huge loss to your company.

Therefore, in the process of purchasing a machine, more on-site inspections are required. The above is what customers need to pay attention to when purchasing laser cutting machine equipment? All of the content, I hope this article is helpful to everyone.
