How A Laser Cutting Machine Works?

A laser cutting machine performs a cutting process by emitting a beam of high intensity laser light having a single wavelength or color. As the laser beam travels from the laser resonator through the path of the machine, it may be focused by a special mirror, lens, curved mirror or beam bender onto a working cutting point on the object.

The precise focus of the laser beam is to increase the thermal density to a very high level, and its high power density allows it to be heated quickly to melt and cut. Wherein the laser beam is added with a compressed gas, such as oxygen or nitrogen, the laser beam will initially dissolve the material, while the high pressure gas will melt the molten metal out of the crack, while the CNC laser cutting machine controls the laser cutting head, which is calculated first. The moving path moves, and the distance between the laser head and the object also needs to be accurately calculated, which is the operation of the laser cutting machine.

The advantage of laser cutting technology compared to general mechanical cutting is that the cutting precision is higher, and the cutting process does not need to contact the object, and the pollution of the object can be reduced and the friction consumption of the laser cutting machine itself can be better maintained. Laser cutting technology, on the other hand, has a small heat-affected zone and is therefore capable of precision or more complex cutting requirements. Laser cutter is a stable, reliable, and very accurate cutting process.
