What is the principle of laser die cutting machine working?

Laser cutting is the laser beam of the laser die cutting machine  emitted from a laser, which is focused into a high power density laser beam of the laser die cutting machine via an optical path system. The laser beam of the laser die cutting machine is irradiated onto the surface of the workpiece to bring the workpiece to a melting point or boiling point, while the high-pressure gas coaxial with the beam of the laser die cutting machine blows away the molten or vaporized metal. As the  laser beam of the laser die cutting machine moves relative to the workpiece.

 

Laser die cutting machine is achieved by applying high power density energy generated by laser focusing for the laser die cutting machine. Under the control of the computer, the laser of the laser die cutting machine is discharged by pulse, thereby outputting a controlled repeated high-frequency pulsed laser for the laser die cutting machine to form a beam of a certain frequency and a certain pulse width, and the pulsed laser beam of the laser die cutting machine is transmitted and reflected through the optical path and focused by the focusing lens group.

Compared with traditional acetylene, plasma and other cutting processes, the laser cutting of the laser die cutting machine speed is fast, the slit is narrow, the heat affected zone is small, the edge of the slit is good,stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramics, glass, composite materials, etc are the application of the laser die cutting machine.

During the cutting process of the laser die cutting machine, the beam of the laser die cutting machine is focused by the lens of the cutting head of the laser die cutting machine  into a small focus, which achieves a high power density at the focus, where in the cutting head is fixed on the z-axis. At this point, the heat input by the laser beam of the laser die cutting machine far exceeds the amount of heat that is reflected, conducted, or diffused by the material.
