How Does the Laser Cutter Work

  1. Introduction of laser cutting machine

The laser cutting machine focuses the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

  1. How does the laser cutting machine work?

Laser cutting machines are widely used in daily life. Now lets’s get to see how a laser cutting machine for tube works.

The laser is a kind of light. Like other natural light, it is produced by the transition of atoms (molecules, ions, etc.). However, it is different from ordinary light in that the laser only relies on spontaneous emission in the first very short time, and the subsequent process is completely determined by the excitation radiation. Therefore, the laser has a very pure color, almost no divergence, extremely high luminous intensity, and high coherence.

Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged through pulses to output a controlled repetitive high-frequency pulsed laser to form a beam with a certain frequency and a certain pulse width. The pulsed laser beam is guided and reflected by the optical path and focused by the focusing lens group. On the surface of the processed object, a small, high-energy-density light spot is formed. The focal spot is located near the surface to be processed and melts or vaporizes the processed material at an instant high temperature. Each high-energy laser pulse instantly sputters a small hole on the surface of the object. Under computer control, the laser processing head and the processed material perform continuous relative movement according to the pre-drawn graphics, so that the object will be processed into the shape you want.

The process parameters (cutting speed, laser power, gas pressure, etc.) and motion trajectory during slitting are controlled by the numerical control system, and the slag at the slit is blown away by a certain pressure of auxiliary gas.
