Laser cutting is the use of 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 cutting of the workpiece. open. Laser cutting is one of the thermal cutting methods.
Features of laser cutting:
⑴ Good cutting quality
Due to the small laser spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality.
⑵ High cutting efficiency
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.
⑶ Fast cutting speed
The material does not need to be clamped and fixed during laser cutting, which not only saves tooling and fixtures, but also saves auxiliary time for loading and unloading.
⑷ Non-contact cutting
There is no contact between the torch and the workpiece during laser cutting, and there is no tool wear. Processing parts of different shapes does not 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.
⑸ There are many types of cutting materials
There are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood, and fiber.
