Laser Cutting

4000 KW Amada Gemini Laser

Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications. Laser cutting works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.
Commercial laser cutters are used to cut sheet material and other shapes such as pipes and tubes.

Creation of the laser beam involves stimulating a lasing material by electrical discharges or lamps within a contained vessel.

As the material is stimulated, the laser beam is reflected inside the vessel by a partial mirror, until it achieves high enough energy to leave as a stream of coherent monochromatic light. Mirrors or fiber optics are usually used to direct the light in a coherent way to a lens, which focuses the light to the work area. The smallest part of the beam is usually less than 0.0.15inch in diameter. Depending upon material thickness, cutting widths as small as 0.005 in are possible.  To start the cutting in the middle of the sheet as apposed to the edge, a pierce is done before each cut. Piercing mostly involves a higher-powered pulsed laser beam which slowly creates a hole in the steel, taking around .5–15 seconds for 12-inch-thick (13 mm) stainless steel, for example.
The inline rays of light from the source laser often are in the range between 1/16 inch to 1/2 inch in diameter. This beam is normally intensified and focused by a lens or a mirror to a very small spot of about 0.001 inch to create a very powerful laser beam. To get the best possible finish during cutting, the direction of beam polarization is rotated as it goes around the periphery of a contoured workpiece. The focal length is usually between 1.5 inches and 3 inches for Sheet metal cutting.

There are many different cutting methods using lasers, with different types used to cut different material. Some of the methods are vaporization, melt and blow, thermal stress cracking, scribing, melt blow and burn, cold cutting and burning stabilized laser cutting.

With our Laser we cut thin metals up 1″ Thick.  If we cut 1″ then we add a blast of water on to the material to help keep the material from over heating.  the thinner the material the fast our laser can cut it.  we can also cut wood,plastic, and some other materials but we typically will choose to do that on our Water jet cutting system instead. Our Waterjet is capable of cutting virtually any material. It can cut the softest rubber to the hardest tool steel. As the material gets thick the cutting speed goes down. As the material gets harder the cutting speed goes down.
