Metal laser cutting machine is specially used for cutting processing of laser cutting equipment, metal material on the market at present the mainstream of the co2 laser cutting machine, fiber laser cutting machine, YAG laser cutting machine, in which co2 laser cutting machine for cutting ability, range is the market mainstream laser cutting equipment, optical fiber laser cutting machine is a new technology, in recent years along with relatively low technical requirements, the growing popularity of metal laser cutting machine equipment.

[scope of application]

It is widely used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway parts, automobile, machinery, precision parts, ships, metallurgical equipment, elevators, household appliances, process gifts, tool processing, decoration, advertising, metal external processing and other manufacturing and processing industries.

Mainly for cutting carbon steel, silicon steel, stainless steel, aluminum alloy, titanium alloy, galvanized plate, pickling plate, aluminum zinc plate, copper and other metal materials such as rapid cutting.

[principle]

The heat input (converted by light energy) of the beam far exceeds the part reflected, transmitted or diffused by the material. The material is quickly heated to the vaporization temperature, which evaporates to form holes. As the beam moves linearly with the material, the holes are continuously formed into slit with narrow width (about 0.1mm, for example). The effect of edge-cutting heat is small and there is no deformation of workpiece. An auxiliary gas suitable for the material being cut is also added in the cutting process. When cutting steel, oxygen is used as auxiliary gas to produce exothermic chemical reaction oxidation material with molten metal, and at the same time to help blow away the slag in the slit. Polypropylene plastic cutting using compressed air, cotton, paper and other flammable materials cutting using inert gas. The auxiliary gas entering the nozzle can also cool the focusing lens to prevent soot from entering the lens base and contaminating the lens and causing the lens to overheat.

Most organic and inorganic materials can be cut by laser. In the industrial manufacturing of heavy metal processing industry, many metal materials, no matter what kind of hardness it has, can be deformation-free cutting (currently using the most advanced metal laser cutting machine can cut the thickness of industrial steel can be close to 20mm). , of course, the high reflectivity material, such as gold, silver, copper and aluminum alloy, they are also a good heat conductor, therefore laser cutting is difficult, can't even cut (some difficult cutting material the pulse laser beam can be used for cutting, due to the extremely high pulse peak value power, can make the material of the absorption coefficient of light beam sudden sharp increase).

【 characteristics 】

High cutting precision and good stability:

Precision ball screw drive mechanism is adopted to optimize CNC system control, which can meet the requirements of precision parts processing.

And the dynamic performance is stable and can work for a long time.

Good cutting section quality:

Adopt the mechanical follow-up cutting head system, the cutting head moves with the height of the plate, the cutting point position always remains the same, so that the cutting seam is flat, smooth, the section does not need the post-processing, suitable for plane or curved surface plate cutting.

Large cutting width, suitable for cutting materials, widely used:

The cutting width of the metal sheet is within 2500mm * 1250mm;

The machinable materials are: ordinary carbon steel, stainless steel, alloy steel, aluminum plate, copper plate, titanium plate and so on.

High cost performance:

For thin plate cutting can replace CO2 laser cutting machine, CNC punch and plate shears, etc., the cost of the whole machine is equivalent to 1/4 of CO2 laser cutting machine and 1/2 of CNC punch.

Low cost of use:

YAG solid-state laser is used, and the main consumables are electric energy, cooling water, auxiliary gas and laser lamp, with an average cost of about 28 yuan per hour.

The core technology:

1, the laser optical path system is stable, after thousands of vibration experiments, the laser optical path system is stable and unchanged;

2, mechanical follow-up cutting head, pure mechanical transmission, stable anti-interference.
