Types of laser cutting machine-Serena

The laser cutting machine can be divided into three types: CO2 laser cutting machine, YAG laser cutting machine, and fiber laser cutting machine. They replace human labor to better complete the cutting task. The three types of laser cutting machine have their own characteristics.

1. CO2 Laser Cutter

CO2 laser cutting machine adopts the laser cutting machine of carbon dioxide laser, which belongs to the molecular gas laser. The working substance is carbon dioxide gas, and the auxiliary gas is nitrogen gas, xenon gas, etc. Its laser wavelength is 10.6 microns. It has good stability and can be used as a laser with high power output.

CO2 laser cutting machine is mainly used to cut non-metallic materials, such as fabrics, jeans we wear, leather, plastic, acrylic, etc. If the power is relatively high, the CO2 laser cutting machine can also cut metal, but the accuracy is generally not too high and cannot cut too thick.

2. YAG Laser Cutter

The YAG laser cutting machine uses a focused high-power density laser beam to irradiate the workpiece so that the irradiated material rapidly melts, vaporizes, ablates or reaches the ignition point. The workpiece is cut. Laser cutting is one of the thermal cutting methods.

YAG laser cutting machine is widely used in advertising sign production, chassis cabinets, textile machinery, food mechanization, saw blades, electrical parts, glasses production and other industries.

3. Fiber Laser Cutter

Fiber laser is a new type of fiber laser developed in the world. It outputs a laser beam with high energy density and gathers it on the surface of the workpiece so that the area irradiated by the ultra-fine focus spot on it is instantly melted and vaporized. The spot is moved by the numerical control mechanical system. Automatic cutting is achieved by irradiating the position. Compared with bulky gas lasers and solid-state lasers, it has apparent advantages, and has gradually developed into an essential candidate in the fields of high-precision laser processing, lidar systems, space technology, and laser medicine.

Fiber laser cutting machine is mainly used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, food machinery, textile machinery, construction machinery,  ships, metallurgical equipment, elevators, household appliances, craft gifts, decoration, advertising, kitchenware processing and other manufacturing and processing industries.

Comparison between laser cutter and traditional cutter

Among the many cutting equipment, laser cutting is just one of them. The following mainly takes the water cutter and the plasma cutter as an example to compare with the laser cutting machine. Let’s take a look at what characteristics they have.

Advantages of laser cutting:

1. Good cutting quality. It can bring you narrow incision and smooth cutting surface. Generally, the cutting seam can be welded without further processing.

2. Fast cutting speed. For example, with 3kW fiber laser power, the cutting speed of 8mm thick carbon steel is 2.3m/min; The cutting speed of 4mm thick stainless steel is 6m/min. Go to XTLASER website and learn more,

3. Clean, safe and pollution-free. The working environment of operators is greatly improved.
