High Power laser Cutting machines: The future?

 With the continuous development of heavy industry, laser cutting technology is developing from thin plate cutting to large size cutting thick plate.Laser cutting has gradually entered the era of high Default

 the new era, the industrial manufacturing of sheet metal cutting precision, speed and thickness of the new requirements. Laser cutting machines are getting more and more powerful.From the perspective of industrial development, high-power laser cutting machine is not only the inevitable product of a certain stage, but also the trend of industrial development.

01 preface

In the field of sheet metal processing, the advantages of laser cutting machine is very prominent. Due to the advantages of high accuracy, high speed, good quality, gradually replaced the traditional processing technology and become the core of the sheet metal cutting equipment.From the rise of laser cutting machine to optical fiber instead of YAG laser cutting machine, and our fleet of machine, roll out to the high power laser cutting machine, large power equipment has become a trend among the cutting plate plate and cutting Efficiency.in Domain Name Is Available to Buy - Domain Name Marketplace recent years, high power laser cutting machine has become one of hot topics in the field of laser cutting. Many enterprises continuously introduce more than 10000 watts of optical fiber laser cutting equipment.For sheet metal processing industry, the birth of the high power cutting equipment, greatly improved the thickness of the sheet metal cutting and efficiency.The emergence of the high-power cutting machine constantly breakthrough the limitation of material cutting http://thickness.As a result of the thick plate processing falling prices form a good circle, promoted the further in the field of laser cutting applications.

02 high-power laser cutting machine

(一) high power cutting machine is introducedLaser cutting machine according to the power can be divided into low power, the power and high power.For the average thickness of stainless steel and carbon steel, low power laser cutting machine can http://cut.In order to cut thick plate and cutting efficiency, high power laser cutting machine is a good way to cut.Therefore, the laser power above 10000 watts of laser cutting machine are collectively referred to as high-power laser cutting machine.

2) The power specifications of the fiber laser are different according to the thickness of the laser cutting metal plate, and the power specifications of the fiber laser selected on the high-power cutting machine are also different. Judging from the current development trend, in the metal processing market, large, medium and small enterprises are gradually upgrading to a variety of specifications, as shown in Table 1. Table 1 High-power fiber laser specifications

(3) The specifications of the gas used When the high-power laser cutting machine is working, in order to ensure the cutting accuracy, cutting speed, cutting section effect and many other advantages, the oxygen purity required is high, generally 99.99%.

03 High-power laser cutting machine features

3.1 Technical breakthrough

(1) High-speed cutting machine with high dynamic performance. The machine tool is equipped with a 10,000 watt fiber laser and adopts a new triangular structure beam. It has the following characteristics: ①The weight is reduced by 30%, and the dynamic performance is significantly improved. 2) The maximum movinq speed can reach 200m/min, and the acceleration is 4G. (③) The weight of the base is increased by about 20%, and the fixing method of the machine tool is changed to eliminate the influence of high acceleration on the machine tool.

(2) The new software system The software and control system are the brains and command center of the machine tool. In addition to the bonuses brought about by the hardware upgrade, the difference in machine performance mainly comes from the difference in software and control system, which is often very different.

(3) Stable cutting can be achieved at a speed of 100M/min ①The response speed of the capacitive sensor is 3 times that of the traditional cutting head ②)The z-axis speed is increased, the operation is more stable without stopping, and the plate cutting efficiency is increased by more than 30%. Improved the efficiency of the skip function, and improved the acceleration adaptation function. 3) Improve the functions of rapid perforation, precision perforation, and remote diagnosis, reserve intelligent interfaces, and realize the "Industry 4.0" function.

3.2 The characteristics of the cutting head The high-power cutting head is the core component to ensure cutting stability under high-power continuous operation conditions. It has the following characteristics:

①High-power cutting head, good sealing, more adequate cooling system, wider focus range, high temperature resistance of the lens

②) Under the influence of the high-power thermal lens effect, when the cutting head works for a long time, the beam will shift in focus. In order to overcome the problem of focal shift, the high-power cutting head adopts a new gas circuit design structure, replacing the nozzle with a new structure, which improves the cutting speed and cutting stability. 3.3 High power laser cutting ability

(1) The thickness of the cut thick plate increases. At present, the thickness of the aluminum alloy plate and the stainless steel plate cut by the high-power laser cutting machine can reach 40mm and 130mm, respectively. With the continuous upgrade of high-power laser cutting machine technology, the thickness of the cutting material will continue to increase , The price of processing thick plates will gradually drop, accelerating the application of high-power laser cutting machines in the field of thick plates.

(2) The cutting efficiency of thin plate is doubled

①When cutting 3 ~ 10mm thick stainless steel plate. The cutting speed of the 10000w laser cutting machine is more than twice that of 6000W. 2 In the carbon steel cutting application, the 10000w laser cutting machine can realize fast bright surface cutting of 18-20mm/s, which is twice the ordinary standard cutting speed.

(3) Carbon steel plates within 12mm can be cut with compressed air or nitrogen, and the cutting efficiency is 6 to 7 times that of oxygen.
