Laser Cutting: Technology And Process
This technology was introduced into industrial practice more than two decades ago. A focusing optic bundles a light beam in a focus. A highly focused and high-energy laser beam acts on a workpiece, creating a melt and metal vapor that is blown out by a high-pressure gas stream.
The laser beam creates a cutting gap or kerf, which can have any cutting edge depending on the laser beam. A wide variety of cutting tasks can be mastered with laser cutting. On the one hand, these tasks include kerfs with millimeter precision in wafer-thin materials and, on the other hand, cuts in metals up to 30 mm thick. Various types of lasers can be used for laser cutting. In the industry are mainly CO2 lasers and fiber lasers in use.
Almost all metallic materials can be processed on the laser cutting systems known on the market – mild steel, stainless steel and aluminum make up the main part. One can easily purchase these machines from a laser cutting machine supplier.
Laser Cutting Costs/Prices:
Basically, concrete numbers cannot be named. The reasons for this are different applications, providers, project sizes, etc. Nevertheless, various cost factors, which can be calculated individually, provide a point of reference:
- Material type
- Material thickness
- Cutting length
- Cutting time
- Number of features (such as openings)
Components And Construction:
The most important components are:
- Laser beam source
- Laser beam guidance
- Processing head (focusing optics) including cutting nozzle
- The laser beam can be guided to the processing point in the near-infrared (fiber laser, disk laser ) via a fiber optic cable, with the CO2 laser via deflection mirrors.
