What should customers pay attention to when purchasing laser cutting machine equipment? When purchasing optical fiber laser cutting machine, many manufacturers do not know how to judge the processing quality of the machine. Buyers often turn a blind eye when choosing laser equipment, sometimes ignoring more important aspects of judgment.
As an effective processing tool, optical fiber laser cutting machine has been widely used in various industries. However, when many people buy and use laser cutting machines, they do not know their processing quality, so how should we judge? What about choosing high-quality and low-cost laser cutting products? The following editor will tell you from four main aspects:,
How to judge the quality of metal laser cutting machine?
First, 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 a vertical line. The deeper the line, the rougher the cross section. The function of the cutting machine we use is to lubricate the cutting part when the thickness of the plate matches the thickness of the metal laser cutting machine, so that no streaks or brittle fracture will occur. Roughness affects not only the appearance of edges, but also properties. In most cases, the lower the roughness, the higher the machining quality.
Second, perpendicularity. For high-power metal laser cutting, the perpendicularity of the cutting margin becomes very important when the thickness of the material we are dealing with exceeds 1 cm. The laser beam diverges when it leaves the focus. Depending on the direction of focus, the notch is widened toward the top or bottom. The cutting allowance exceeds the vertical line by several millimeters. The more vertical the margin, the higher the cutting quality.
Third, the cutting width. Generally speaking, the cutting width will not affect the quality, but when a particularly accurate pattern is formed inside the part, the cutting width needs to reach the minimum inner diameter that can be completed. When the thickness of the plate is increased, the cutting width is also increased. Therefore, to ensure the same high accuracy, no matter how large the blocking width is, the workpiece should be stable in the laser cutting machine area.
4、 Burrs. In the process of metal laser cutting machine, the laser beam irradiates the surface of the workpiece and continuously outputs energy to make the surface of the workpiece vaporize, then evaporate, and the slag on the surface of the workpiece is blown away by the auxiliary gas. If auxiliary gas is not used, the slag will form burrs after cooling, and the burrs will adhere to the cutting surface. Since deburring requires extra work, the cutting quality can be judged intuitively by querying the number of burrs.
What should we pay attention to when purchasing laser cutting machines?
Some suggestions for friends who need to purchase optical fiber laser cutting machine:
1. Does the manufacturer of laser cutting machine have its own production strength? Usually, the investigation can be carried out according to the quality and quantity of the laser cutting machine customers of the manufacturer. Among laser cutting machines, companies that should choose more than 100 high-power laser cutting machines should be selected, and these equipment should produce high-power cutting thick metal plates annually.. As many small companies only sell a few units every year, they may stop production and close the door at any time, which has a great impact on after-sales.
2. The price of laser cutting machine does not conform to the market price. Now, the price of laser cutting machine, which is very popular in the market, is usually within a certain range. If the price is higher than the price, it is necessary to contact the merchant. If the price is lower than this price, it may be inferior, second-hand or refurbished, and it is more likely to be an imitation laser cutting machine. In particular, if you can spend hundreds of thousands of dollars to buy a high-power machine, that is the temptation of Apple poisoning. Don't get caught.
3. Can relevant customer services respond positively? If the manufacturer pats his chest and tells you that there is an office in the after-sales service center, as a customer, you need to go to the site for inspection and inspection. Otherwise, if there is no local service, there is a problem in the office or after-sales department. If there is a problem later, it cannot be repaired in time. You can only wait for 2-3 days to repair the equipment, which will cause huge losses to your company.
Therefore, more on-site inspections are required during the purchase of the machine. These are the matters that customers should pay attention to when purchasing laser cutting machine equipment? I hope this article can help you.
