The laser cutting machines belong to the category of sheet metal machines. The machine allows for the cutting of materials through the use of a powerful laser. The laser beam of the machine involves stimulating a lasing material using electrical discharges within a closed container. When the material is stimulated, the beam is reflected internally by means of a mirror. Then, it achieves sufficient energy to escape as a stream of monochromatic coherent light. Thanks to mirrors or fibre optics, the light is sent to a lens, which focuses the light on the work zone and the material to be cut.
This machine is very precise. It uses a focusing lens to concentrate the energy onto a precise point. Usually, the diameter of the beam is ¾, which allows it to complete very precise operations. The CO2 operating system represents the most popular category of laser machines. There are several kinds of laser machines, which are usually ranked according to the following criteria:
CNC or not
The laser machine can operate on most of these materials
Metal, textile, paper, glass, cardboard, ceramic, and leather. However, in some cases (with soft materials for example), the waterjet machine is recommended. Some materials require a specific set-up. For example, silver and copper are reflective, making it much more difficult for the machine to operate with these kinds of materials.
Advantages of the laser cutting machine
The narrow laser cut width allows maximum material utilisation and a very limited risk of waste. Manufacturers are rapidly innovating in this area through the diversification of materials and increasing the thickness of the cutting process. The laser cutters are considered to be more precise and consume less energy than plasma cutting machines. Newer cutting machines are usually CNC (Computer numerical control) in order to produce faster functioning with a higher precision.
However, this machine is very powerful and requires a very good understanding of the cutting process and safety rules.
Area of use
As the machine is very polyvalent, a very wide range of professionals use it. The military industry, wood and metal production and jewelry are all examples of industries where the laser cutting machine is commonly used.
