How to buy laser cutting machine

XT Laser-fiber laser cutting machine

There are thousands of domestic fiber laser cutting machine manufacturers, even more. With so many laser cutting machine manufacturers and brands, how do our customers purchase laser cutting machines, how do they purchase laser cutting machines, and what should we pay attention to when choosing fiber laser cutting machines? When selecting laser cutting machine, especially optical fiber laser cutting machine, you must look at its software system and hardware facilities. General hardware facilities include its fiber laser and cutting head. In addition to collecting information about the company’s brand strength and reputation on the Internet, people outside the industry also need to understand the components and processing application knowledge of a fiber laser cutting machine. Fiber laser cutting machines are expensive, often hundreds of thousands or millions. In the process of selecting and purchasing laser cutting machines, there are many factors that need to be understood. We summarized some selection techniques and methods for your reference only.

1. Precautions when purchasing fiber laser cutting machine.

A. Control software

The control software, also known as the NC system, will also affect the cutting accuracy of the fiber laser cutting machine. The optical fiber laser cutting machine produced by general manufacturers adopts imported CNC system, but some manufacturers are developing their own CUT software, but relatively few. At present, Shanghai Bochu CNC system is the most widely used one by domestic manufacturers.

B. Fiber laser.

Fiber laser is the core component of fiber laser cutting machine, and also the “power source” of its cutting operation. The service life, cutting speed and cutting quality of a device largely depend on the fiber laser. Frankly speaking, the performance of foreign fiber lasers is no more than one or two levels higher than that of domestic fiber lasers, especially the high-power fiber lasers above 700W. The reason why some fiber laser cutting machine manufacturers with the same power are expensive is that they use internationally famous fiber laser brands, such as SPI, IPG and Rofin. Many manufacturers claim to use imported fiber lasers, but in fact they use domestic lasers. How to distinguish. It’s very simple. Select materials with the same thickness and go to two different manufacturers for proofing, one of which must be a large manufacturer and an old brand. Then select a machine with the same power and compare the cutting speed and cutting quality.

C. Cutting head

The cutting head of the laser cutting machine is a laser output device, which is composed of nozzle, focusing lens and focusing tracking system. The cutting head of the laser cutting machine will walk according to the set cutting path, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses and different cutting methods. The high-power optical fiber cutting machine produced by Jinan Xintian Laser adopts a cutting head with skip function, which can adjust the cutting height accordingly, which is very convenient.

D. Servo motor.

Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an indirect speed change device for auxiliary motor. It provides power for the operation of the fiber laser cutting machine, but also affects the cutting accuracy. It is an auxiliary motor indirect transmission device that controls the mechanical operation of the engine in the servo system. The gantry servo drive structure and high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeated positioning accuracy of the laser cutting machine. The servo motor of high-power fiber laser cutting machine generally adopts the well-known Japanese motor brand “Yaskawa Motor”. I believe that many friends in the machinery manufacturing industry are familiar with the 100 year history of Yaskawa Electric. Therefore, the motor is also a very important part, so you must pay attention when purchasing.

E. Cooling device.

The overall power of the fiber laser is relatively large, and the heat generated by the fiber laser is large. To ensure the service life, professional cooling devices must be selected. Water chiller is the cooling device of laser cutting machine. It can quickly and efficiently cool lasers, spindles and other equipment. The current water chiller has advanced functions such as input and output control equipment switch, cooling water flow, high and low temperature alarm, and its performance is more stable, so as to ensure that the fiber laser cutting machine works at constant temperature and extend the service life of the fiber laser.

F. Machine tool structure.

The structure of the machine tool is an important factor affecting the cutting accuracy, stability and durability of the fiber laser cutting machine. The cutting accuracy of the fiber laser cutting machine will decrease with the increase of the use time of the machine tool. Machine wear and aging of transmission structure are all the reasons for the decline of precision.

2、 Performance knowledge to pay attention to when purchasing optical fiber laser cutting machine.

As for the performance of optical fiber laser cutting, it can be summarized as three points: how thick can be cut, how many pieces can be cut, and how good can be cut.

Some manufacturers claim that 2000W can cut carbon steel with a thickness of 12mm or more. In actual cutting, it can cut, and the cutting effect seems to be barely acceptable. But there is a problem to pay attention to. The machine has problems of excessive performance and performance overdraft. Just like a stunted child, if he does some physical work overload for a long time, it will cause great harm to his body.

These are the problems that should be paid attention to when selecting the laser cutting machine. If you want to ensure the best performance of a high-quality laser cutting machine, you must check its hardware and software facilities. The hardware and software facilities are very good. Able to select a good laser cutting machine.
