Laser cutting machines occupy an important position in modern manufacturing. This article mainly introduces laser cutting machines and their working principles.

What is laser cutting?

Laser cutting is a high-precision material processing method, it’s depending on high-energy density laser beam to achieve cutting, engraving and drilling of various materials. Includes metallic and non-metallic materials, Such as carbon steel, aluminum, stainless steel, brass,  plastic, wood, etc. The core of this technology is to focus the laser beam onto a tiny focus; therefore, the energy density of the beam will become extremely high that it can instantly heat parts of the material to high temperatures, making it burn, melt or evaporate. Eventually cutting or engraving purposes can be achieved.

Due to its high-precision, fast, non-contact processing, suitability for a variety of materials, and ability to achieve cutting of complex geometric shapes, laser cutting machines are widely used in manufacturing, aerospace, medical and other fields.

How does a laser cutter work?

Before knowing how the laser cutting machine works, please allow me to give you a brief introduction to“what is laser light”. 

A laser is a kind of enhanced light obtained by stimulated radiation.The laser cutting machine will emit a high-energy laser beam from the laser resonator and the beam will be sent to the cutting head of the moving device through the optical path system. The computer numerical control system (CNC) accurately controls the position and movement of the beam according to the pre-designed cutting contour and shape, and adjust the intensity, focus position and movement speed of the laser.The laser beam is focused by the optical system and irradiated on the surface of the material. 

Once focused, the material in the local area is quickly melted or evaporated. Laser cutting machines often use airflow or oxidizers to blow away the processed material to keep the cutting path clear. This can also help cool the workpiece surface and reduce cutting marks. This process enables cutting and engraving of materials efficiently and accurately, making laser cutting machines an important tool in modern manufacturing and engineering.

Types of laser cutters

There are roughly two types of laser cutting machines on the market: CO2 laser cutting machine and Fiber laser cutting machine. Although there are very similar in construction, the materials and fields used by each laser cutting machine are very different.

CO2 laser cutting machine: The laser is generated by electrically stimulating a mixture of gases(mainly carbon dioxide).This is a common type of laser cutter because they are low powered, relatively cheap and efficient. CO2 laser cutting machine is suitable for cutting non-metallic materials, such as wood, cardboard, leather, acrylic, glass and some other plastics and forms, so CO2 laser cutting machine is usually widely used in the fields of art and decoration, textile, packaging and advertising.

Fiber laser cutting machine: Fiber laser cutting machine is a “process revolution” in sheet metal processing, the laser is generated by a fiber-optic laser. Fiber laser cutting machines are gradually replacing many traditional metal cutting processes. Because of its high efficiency, high precision, and ability to handle various complex sheet metal processing requirements, and compared with CO2 laser cutting machines, it has higher electro-optical conversion rate, better processing effect, and lower maintenance cost, so it is more popular among major manufacturers. 

Fiber laser cutting machines are mainly suitable for cutting metal materials, such as steel, aluminum and copper, so they are often used in metal processing, automobile manufacturing, aerospace and electronic manufacturing and other fields.
