Introduction and use of different types of laser machines

Laser equipment can be divided into three categories: laser marking machines, laser welding machines, and laser cutting machines.Today, mainly based on the similarities in performance, let’s talk about laser cutting machines and laser marking machines.

一、Laser Cutting

At present, the laser cutting machines used for material cutting on the market can be roughly divided into two types: fiber laser cutting machines and CO2 laser cutting machines.

(1)CO2 laser cutting machine is also called carbon dioxide laser cutting machine, which is mainly used in laser cutting of non-metallic materials. It is widely used in production and life processing. The reason why CO2 laser cutting machine is called carbon dioxide laser cutting machine is because it mainly uses carbon dioxide laser as the main processing emission principle, uses carbon dioxide gas as the main processing core of gas, and cooperates with nitrogen and other gases as the core. The wavelength of the laser is roughly 10.6 microns, and the stable performance is better.CO2 laser cutting machine is mainly suitable for non-metallic materials, such as cloth, acrylic or leather, as well as plastic and some glass products.Printing plate making, clothing leather, embroidery, decoration, photo frame making, advertising and other industries.

(2)Fiber laser cutting machine is different from CO2 laser cutting machine, it uses fiber laser as the main power to work. Fiber laser is a new type of fiber laser newly developed in the world. It outputs high-energy-density laser beams and gathers them on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and gasified, and the spot is moved by the numerical control mechanical system. Automatic cutting is realized by irradiating the position, with high speed and high precision.Mainly suitable for cutting metals, such as carbon steel, stainless steel, galvanized sheet, etc. Mainly used in the automobile industry, advertising industry, decoration industry, sheet metal processing and other industries.

二、Laser marking

(1)Fiber laser marking machine is a marking method that uses high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark.

The fiber laser marking machine can print various characters, symbols and patterns, etc., and the character size can range from millimeters to microns, which has special significance for the anti-counterfeiting of products. Due to the small size and fine workmanship after laser focusing, some processes that cannot be realized by conventional methods can be completed.

Fiber laser marking machine uses laser beams to permanently mark the surface of various materials, such as printing various types of materials on gold, silver, copper, iron, zinc, aluminum, stainless steel, and stainless Exquisite pattern or text, LOGO, etc.

(2)CO2 laser marking machine, namely carbon dioxide laser marking machine, is a laser galvanometer marking machine that uses CO2 gas as the working medium. The CO2 laser uses CO2 gas as the medium. After the laser energy is amplified, scanned by the galvanometer and focused by the F-Theta mirror, under the control of the computer and the laser marking control card, images, characters, and numbers can be printed on the workpiece as required and line marking.

Suitable for bamboo and wood products, leather rubber, plastic shell, cloth, acrylic, paper products, MDF, marble, PVC and other non-metallic surfaces.

(3)Ultraviolet laser marking is cold processing. The ultraviolet laser processing process is called "photoetching" effect. "Cold processing" has (ultraviolet) photons with high load energy, which can break the chemical bonds in materials (especially organic materials) or surrounding media. To cause non-thermal process damage to the material. There is no heating or thermal deformation on the inner layer and nearby areas of the processed surface.

Ultraviolet laser marking machine is mainly based on its unique low-power laser beam, which is especially suitable for the high-end market of ultra-fine processing. The surface marking of packaging bottles for cosmetics, medicines, food and other polymer materials has fine effects and clear and firm marks. Better than inkjet coding and no pollution.

Applicable to glass products, crystal products, bamboo and wood products, leather rubber, plastic shell, acrylic, paper products, MDF, PVC PCB, metal products and other material surfaces

Used in advertising industry, packaging industry, furniture, electronic devices, plastic products, gift customization, etc.
