Due to its ability to accurately cut component parts with a less than a 0.130mm tolerance, Laser cutting is the most sought after profiling technology. The position and the cutting path of the laser is precisely controlled by computer controlled software which allows very fine detail to be handled with ease and allows for a much higher definition and quality of cut when compared to other types of manufacturing. Laser cutting systems work by creating a gas laser where CO2 is mixed with other gases, helium and nitrogen, to form a lasing medium.

Laser cutting systems are at there effective best when producing a precise cut because of the accuracy of the fine laser contact. Heat is generated but because of the precise contact with the material it generates only the narrowest heat-affected area. Laser cutting can produce complex internal and external detail, small diameter holes can be produced and remove the need for further machining operations

The beam from the laser is focused on to the surface of the material being cut by means of a lens. The focused laser beam heats the material surface and a very local melt capillary is quickly established throughout the depth of the material.

The great majority of CO2 laser cutting is performed using an assist gas. The significant feature of gas assisted laser cutting is that the molten material is ejected from the base of the capillary by a jet of gas coaxial with the laser beam. Stainless steel is cut utilizing nitrogen as the assist gas, which prevents oxide on the cut edge, eliminating secondary processing prior to welding.

The cut is generated by either moving the focused laser beam across the surface of the stationary material or by keeping the laser beam stationary and moving the work piece.
