Many metal fabrication shops still employ traditional cutting methods such as lathing and sawing but with advanced technology, laser cutting became at the forefront of fabrication. Laser cutting service is usually needed in industrial cutting applications for increased speed, accuracy, and high precision. This cutting technique can cut complicated shapes and has the ability to produce even smaller diameter holes with an excellent edge. With laser cutting technology, fabricators can still cope with the rising demands while producing high-quality parts.
Laser cutting is typically done through electrical discharges that generate a high powered beam of light. The laser beams are able to cut different material thickness through the use of computer-controlled technology. Anything that comes across the beam’s path is cut with high precision. This method can be performed in three different ways. If you are looking for a laser cutting service, it is helpful to know each of these technologies for your particular project. Knowing which laser cutting technique is best suited for your application is vital to the success of your project.
Vaporization Technique Laser beams can reach and even exceed the melting points of different materials. Upon reaching the material’s boiling point, the heated surface melts which creates a hole. As that surface continues to be heated, it expands and melts. The excess heat boils it even more which leads to the vaporization of the molten parts. In order to achieve the best results, the laser cutting service specialist will advise you on what type of material works best with this technique.
Melt and Blow Cutting or Fusion This last method utilizes a highly pressurized gas jet that blows the molten materials. As the beam continues to heat the surface, the gas also continually blows the molten particles of the kerf. This constant heating is what cut the material into the desired shape of form. Fusion laser cutting service is best for cutting metal surfaces.
Thermal Stress Also referred to as cracking, thermal stress is a good alternative to use in cutting brittle materials such as glass and acrylic. Regulated thermal stressing is accomplished by focusing the beam on the surface of a material, leading to localized heating and thermal expansion of the parts creating a crack. The expansion of the crack is being controlled by moving the laser beam.
