Laser cutting is one of the thermal cutting methods. Laser cutting technology uses a focused high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by the high-speed airflow coaxial with the beam to realize the workpiece Cut open. So, what are the characteristics of laser cutting technology compared with other thermal cutting methods? Let us introduce Leapion laser:
Thermal cutting is an indispensable working method for metal material blanking, scrap disassembly, installation and dismantling in the industrial sector, including gas cutting, arc cutting, plasma arc cutting, laser cutting, etc.
Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can obtain better cutting quality.
1) The laser cutting incision is narrow, the two sides of the incision seam are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.
2) The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as the last process without mechanical processing, and the parts can be used directly.
3) After the material is laser cut, the width of the heat-affected zone is very small, and the performance of the material near the slit is almost unaffected.
4) The laser-cut workpiece has small deformation, high cutting accuracy, good geometry of the cutting seam, and the cross-sectional shape of the cutting seam presents a relatively regular rectangle.
Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple numerical control worktables, and the entire cutting process can be fully numerically controlled. During operation, only by changing the numerical control program, it can be applied to the cutting of parts of different shapes, which can be used for two-dimensional cutting and three-dimensional cutting.
Using a laser with a power of 1200W to cut 2mm thick low carbon steel plates, the cutting speed can reach 15000px/min; for 5mm thick polypropylene resin plates, the cutting speed can reach 30000px/min.
In addition, the material does not need to be clamped and fixed during laser cutting, which not only saves tooling fixtures, but also saves auxiliary time for loading and unloading.
4. Laser cutting is non-contact cutting
There is no contact between the torch and the workpiece during laser cutting, and there is no tool wear. To process 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.
Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood, and fiber.
However, for different materials, due to their own thermophysical properties and different absorption rates for lasers, they exhibit different laser cutting adaptability.
