CNC Laser Cutting process uses the energy released by the laser beam to illuminate the surface of the metal sheet to melt and evaporate the metal. The laser source is generally a carbon dioxide laser beam with an operating power of 500 to 2,500 watts. The level of this power is lower than that required by many domestic electric heaters, but the laser beam is concentrated in a small area by the lens and the mirror. The high concentration of energy enables rapid local heating to evaporate the metal. In addition, since the energy is very concentrated, only a small amount of heat is transferred to other parts of the metal, and the deformation is small or no deformation. The laser can be used to cut the complex shape of the blank very accurately, and the cut blank does not have to be further processed. Processing.
We have laser cutting machine to provide professional laser cutting service with competitive prices for you.
If you need customized high-quality and low-cost parts, itwillbea good idea to choose us.
● Good cutting quality. Laser cutting can achieve better cutting quality due to the small laser spot, high energy density and fast cutting speed.
▶ The laser cutting slit is narrow, the slits are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.
▶ The cutting surface is smooth and beautiful, the surface roughness is only a few tens of microns, and even laser cutting can be used as the last process. And the parts can be used directly with no machining.
▶ After laser cutting, the performance of the material near the slit is almost unaffected, and the workpiece has small deformation, high cutting precision and good geometry of the slit.
● High cutting efficiency.
● Fast cutting speed.
● Non-contact cutting. Machining parts of different shapes, there is no need to change the "tool", just change the output parameters of the laser. The laser cutting process has low noise, low vibration and no pollution.
● In the field of automobile manufacturing, it is possible to cut the body sheet of complicated shape and various curved parts. In the aerospace industry, laser cutting technology is mainly used for the cutting of special aviation materials, such as titanium alloy, aluminum alloy, nickel alloy, chrome alloy, stainless steel, cerium oxide, composite materials, plastics, etc.
● Laser cutting technology also has a wide range of applications in the field of non-metallic materials. It can cut not only high hardness and brittle materials such as silicon nitride, ceramics, quartz, but also flexible materials such as cloth, paper, plastic sheet, rubber, etc.
Metal: Aluminum, Stainless steel, steel, etc.
Plastic: PC, PMMA, etc.
