Laser cutting uses a focused high power density laser beam to irradiate the workpiece, rapidly irradiate, vaporize, ablate, or reach the ignition point of the irradiated material. At the same time, the workpiece is cut by blowing molten material with a high-speed airflow coaxial with the beam. open. Laser cutting is one of the hot cutting methods. The specific advantages of laser cutting compared to other thermal cutting methods can be summarized as follows: Good cutting quality: Due to the small laser spot, high energy density, and high cutting speed, laser cutting can achieve better cutting quality. 1 The laser cutting incision is narrow, the slits are parallel on both sides and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05 mm. 2 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 without mechanical processing. Components can be used directly. 3 After the laser cutting, the width of the heat affected zone is very small, and the performance of the material near the slit is hardly affected, and the workpiece deformation is small, the cutting accuracy is high, the geometry of the slit is good, and the cross section of the slit shows a more regular pattern. Rectangles. Cutting speed: Cutting 2mm thick low-carbon steel plate with laser with 1200W power, cutting speed up to 15000px/min; cutting polypropylene resin plate with 5mm thickness, cutting speed up to 30000px/min. The material does not need to be clamped during laser cutting, which can save the fixture and save the auxiliary time for loading and unloading. Non-contact cutting: When the laser cutting, the torch and the workpiece have no contact, there is no tool wear. To machine parts of different shapes, there is no need to replace the "tool", just change the output parameters of the laser. The laser cutting process has low noise, little vibration, and no pollution. The types of cutting materials are many: Compared with oxyacetylene cutting and plasma cutting, there are many kinds of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood, and fibers. However, different materials have different laser cutting suitability due to their own thermophysical properties and different laser absorption rates. In summary, from the perspective of market conditions, the laser processing market has grown steadily. Under the backdrop of weak macroeconomic and industrial demand, laser processing equipment has maintained a steady growth in industry scale with its business demand in the high-end processing market. Compared with the traditional machine tool cutting and other thermal processing, laser processing has multiple technical advantages, which are in line with the requirements of high-precision, low wear, high efficiency and other requirements of the high-end processing market.

Five advantages of laser processing compared to other thermal cutting methods
High cutting efficiency: Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple numerically controlled tables, and the entire cutting process can be fully realized with numerical control. In operation, only by changing the numerical control program, it is possible to apply the cutting of different shapes of parts, both for two-dimensional cutting and for three-dimensional cutting.
