2560 laser cutting machine

During the cutting process of the 2560 laser cutting machine, the beam is focused into a small focal point through the lens of the cutting head, achieving a high power density at the focal point, where the cutting head is fixed on the z-axis. At this point, the heat input by the beam is far away from the local heat reflected, conducted, or diffused by the data. The data is quickly heated to the temperature of condensation and vaporization. At the same time, a high-speed airflow blows out the condensed and vaporized data from the coaxial or non coaxial side, forming a hole for data cutting. With the relative movement between the focus and the data, the hole forms a continuous narrow slit, completing the cutting of the data.

Laser is a type of light that, like other natural light, is generated by the transition of atoms (molecules or ions, etc.). But it is different from ordinary light in that laser only relies on spontaneous emission for a very short period of time, and the subsequent process is completely determined by the excitation radiation. Therefore, laser has pure color, almost no divergent directionality, luminous intensity, and high coherence.

Laser cutting is accomplished by utilizing the high power density energy generated by laser focusing. Under the control of a computer, the laser is pulsed to discharge and output controlled high-frequency pulsed laser, forming a beam of frequency and pulse width. The pulsed laser beam is transmitted and reflected through an optical path and focused on the surface of the processed object by a focusing lens group, forming fine, density light spots. The focal spot is located near the left side of the surface to be processed, and the processed material is condensed or vaporized at high temperature in an instant. Each laser pulse instantly splashes a small hole on the surface of the object. Under computer control, the laser processing head and the processed material stop continuous relative motion and dot according to the pre drawn shape, thus processing the object into the desired shape.

The process parameters (cutting speed, laser power, gas pressure, etc.) and motion trajectory during cutting are controlled by the CNC system, and the slag at the cutting seam is blown away by the auxiliary gas under pressure.
