Laser cutting non-ferrous metal sheet, a strong artistic style

To make metal plates into metal crafts is a very complicated technical task. The production process requires many processes, such as cutting, bending, bending, welding and other mechanical processing.

Among them, the cutting process is a more important process. There are many traditional metal cutting methods. Their common problems are low efficiency, poor molding quality and seldom can meet the needs of mass production. After the birth of the laser cutting process, advanced laser technology has brought more possibilities for the manufacture of metal crafts. Especially in the processing of non-ferrous metals, the laser cutting machine brings a strong artistic style to the non-ferrous metals with its flexibility.

The metal decorations in this clothing store use laser-cut patterns on the copper sheet, so that it can be deformed at any curved surface, so that the metal has great plasticity and does not blend into the store environment. Obtrusively.

Laser cutting machine is used to cut non-ferrous metals-copper and brass. Both materials have high reflectivity and very good thermal conductivity. Brass with a thickness of less than 1mm can be processed by nitrogen laser cutting; for copper with a thickness of less than 2mm, oxygen must be used for laser cutting processing gas. It should be pointed out that when laser cutting copper and brass is used, a 'reflection absorption' device must be installed on the system.

The red copper cannot be cut with CO2 laser beam because of its high reflectivity. Brass uses a higher laser power, and the auxiliary gas uses air or oxygen, which can cut thinner plates.

The advantages of laser cutting non-ferrous metals

The incision is smooth and flat, and generally does not require subsequent processing; the cutting heat affected zone is small, the plate deformation is small, and the slit is narrow; the incision has no mechanical stress, no shearing burr; high processing accuracy, good repeatability, and no damage to the material Surface; CNC programming, can process any plan, can cut the whole board with a large format, no need to open the mold, economical and time-saving; Wide application range, laser can cut many materials, including non-metallic plates such as plexiglass, plastic, etc. And a variety of metal materials such as stainless steel, carbon steel, alloy steel, aluminum plate, etc.

Of course, in the actual operation process, the cutting ability of the laser cutting machine is also affected by many factors such as the type of laser, cutting environment, cutting speed, auxiliary gas, etc. Therefore, in the processing of non-ferrous metals, laser cutting The debugging of the machine is also particularly important.
