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 machines. Purchasers are often blind when choosing laser equipment, and sometimes ignore the more important aspects of judgment.
As an effective processing tool, fiber laser cutting machine has been widely used in various industries. However, many people do not know the processing quality of the laser cutting machine when they buy and use it. How should we judge it? Then buy high-quality and low-cost laser cutting products? Next, Xiaobian will tell you about the metal laser cutting machine from four major aspects. How to judge whether its quality is superior or not?
1、 Roughness
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 cross-sectional surface. The power of the cutting machine we use is a metal laser cutting machine when it matches the thickness of the plate. The section it cuts is lubricated, free of stripes and brittle fracture. Roughness affects not only the appearance of the edge, but also the characteristics. In most cases, the lower the roughness, the higher the quality.
2、 Verticality
For high-power metal laser cutting, when the thickness of the material to be processed exceeds 1cm, the perpendicularity of the cutting edge becomes very important. When it is far from the focus, the laser beam becomes divergent. Depending on the orientation of the focal point, the incision widens toward the top or bottom. The cutting edge exceeds the vertical line by a few millimeters. The more vertical the edge, the higher the cutting 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 minimum inner diameter that can be completed. When the sheet thickness is added, the cutting width is also added. Therefore, to ensure equal high accuracy, no matter how large the cutting width is, the workpiece should be stable in the area of the laser cutting machine.
4、 Burr
In the process of metal laser cutting machine processing, the laser beam irradiates the surface of the workpiece, continuously outputs energy, vaporizes the surface of the workpiece, then transpiration, and blows away the slag on the surface of the workpiece by auxiliary gas. If auxiliary gas is not used, the slag will form burr and attach to the cut surface after cooling. Since burr removal requires extra workload, the quality of cutting can be intuitively judged by querying the number of burrs.
Some suggestions for friends who need to buy fiber laser cutting machines:
1. Does the manufacturer of laser cutting machine have its own production strength. Generally, we can investigate the quality and quantity of the laser cutting machine customers of this manufacturer. In terms of laser cutting machines, we should choose companies with an annual output of more than 100 high-power laser cutting machines for cutting thick sheet metal materials. Because many small companies only sell a few units a year, they may shut down at any time, which has a lot of impact on after-sales.
2. The price of the laser cutting machine does not conform to 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, you should talk to the business if it is high. If it is below this price, it may be inferior or second-hand or refurbished, or even counterfeit laser cutting machines. In particular, it is the temptation of poisonous apples to buy a high-power machine with hundreds of thousands of dollars. Don't fall into it
3. Can the relevant customer service respond positively? If a manufacturer tells you that there is an office in your after-sales service place, as a customer, you need to go to the site for investigation. Otherwise, if there is no local office or after-sales department, if there is a problem in the future, it will not be able to repair the equipment in time. You can only wait 2-3 days to repair the equipment, which will be a great loss to your company
Therefore, in the process of purchasing the machine, we need to pay more attention to on-the-spot investigation. The above is what customers need to pay attention to when purchasing laser cutting machine equipment? I hope this article will help you.
