What Is Fiber Laser Cutting and how does it work?

Fiber laser cutting makes use of a kind of solid-state laser to melt and pierce metals, reaching a precise and efficient cut. The laser medium for this technological know-how is optical fibre, as adverse to gas or crystal, giving fiber laser cutting its name.

Knowing that a laser is centred light, it makes feel that optical fibre can intensify this beam – therefore why fibre is the ‘active gain medium’ used to increase the laser to a greater strength state.

Fiber laser cutters can cut a vary of substances and thicknesses relying on the capability of the equipment. Most fiber laser machines can cut up cut stainless metal up to 10mm thick.

The fiber laser cutting machine works on the following principles：

Fiber laser technology generates a focused, high-powered laser beam the use of stimulated radiation. A laser diode emits light, which is despatched to the fiber optic cable to be amplified. When this effective laser hits the material surface, the high-intensity light is absorbed and transformed into heat, which melts the surface.

A high-speed airflow that is parallel with the laser beam is used to blow away any molten material, permitting the workpiece to be cut.

The fiber laser’s first point of contact with the material ought to be more intense than subsequent interactions because, rather than genuinely cutting thru the material, this first contact have to pierce it. This requires using a high-powered pulse beam that works to put a hole in the material that lasts for about roughly ten seconds for a twelve millimeter sheet of stainless steel. Simultaneously, a high-speed airflow will clear out the particles to show a clear image of the output.

Typically, a fiber laser cutting machine makes use of computerised digital manage technology, which lets in the cutting data to be obtained from the computer-aided format workstation. These technologies aid in controlling both the floor of the material or the laser itself closer to producing a specific pattern or design.
