fiber laser cutting machine introduction

As demands for laser cutting machines for industries are increasing, laser cutting equipment is facing new challenges. In particular, the requirements for the process are getting higher and higher, and the upgrading of technology is particularly important. In some industries where laser cutting machines are not in contact, they have started to use fiber laser cutting machines. However, the laser cutting machine is not omnipotent, and is also limited by some materials. As we all know, as the mainstream cutting equipment in the world today, fiber laser cutting machine has become the best choice for cutting various materials due to its wide cutting range, fast cutting speed, good cutting effect and maintenance-free advantages. Especially suitable for cutting metal materials.So what kinds of metal are suitable for fiber laser cutting machines?

The following knowledge points are listed below:

1. The laser cutting machine principle:

The fiber laser cutting machine compared with the traditional laser cutting using a single circular laser beam, the new cutting process uses a complex laser beam shape. The unique focusing characteristics of high-power single-mode fiber lasers are used to generate complex beam shapes and make it possible to separate a portion of the overall laser energy in order to create a "keyhole" for laser welding or laser cutting applications. The rest of the energy will be distributed to the melt; before this, the main beam is used to create an appropriate high vapor pressure distribution on the surface of the molten material.

2. The fiber laser cutting machine features:

a).The fiber laser henerator has high electrical-optical conversion efficiency, and the conversion efficiency is more than 30%. The use of air cooling can greatly save power consumption during operation, save operating costs, and achieve the highest production efficiency. ;

b).The laser only needs electrical energy during operation, and does not require additional gas for laser generation, with the lowest operating and maintenance costs;

c). The fiber laser adopts semiconductor mould and redundant design. There is no optical lens in the resonant cavity, which does not require startup time. It has the advantages of no adjustment, maintenance, and high stability. It reduces the cost of accessories and maintenance time, which is traditional. Incomparable by laser;

d). The output wavelength of the fiber laser is 1.064 microns, which is 1/10 of the CO2 wavelength. The output beam has good quality and high power density, which is very conducive to the absorption of metal materials, and has excellent cutting and welding capabilities, thereby making the processing cost lowest;

e). The optical transmission of the whole machine is through optical fiber, and does not require complex light guide systems such as reflecting mirrors. The optical path is simple, the structure is stable, and the external optical path is maintenance-free;

3. The fiber laser cutting machine cutting materials and thickness

  The fiber laser cutting machine cutting all metal materials include :Stainless steel, carbon steel, alloy steel, brass, copper, manganese steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminized zinc plate, pickled sheet, copper, silver, gold, titanium and other metal sheet plates.

 Cutting different thickness metal need different laser power.Cutting thickness as reference :

1000W:5mm stainless steel, 10mm carbon steel

1500W:6mm stainless steel, 12mm carbon steel

2000W:8mm stainless steel, 15mm carbon steel

3000W:10mm stainless steel, 20mm carbon steel

4000W:12mm stainless steel, 22mm carbon steel

4. The component of fiber laser cutting machine:

  1). Fiber laser source : The laser is the core of the laser equipment. At present, the fiber laser brands on the market include IPG, Reco, Nlight, etc. With the development of technology, domestic laser brands such as Reco, etc. have also emerged and are gradually recognized by the market with high cost performance. Laser can directly affect the cutting efficiency, cutting quality, service life, etc. of the equipment. Therefore, the laser has also become one of the first factors to be investigated when purchasing equipment.

2). Cutting head: The cutting head of the laser cutting machine is a laser output device, which is composed of a nozzle, a focusing lens and a focusing tracking system. The cutting head of the laser cutting machine will walk according to the set cutting trajectory, but under different materials, different thicknesses and different cutting methods, the height of the laser cutting head needs to be adjusted and controlled.

3). Servo motor: Servo motor refers to an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect transmission. The servo motor can control the speed and the position accuracy is very accurate, and can convert the voltage signal into torque and speed to drive the control object. The high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeated positioning accuracy of the laser cutting machine.

4). Cutting software: China most laser cutting machine equip Cypcut cutting software,much stable cutting and powerful function.
