laser cutting is a process where a material is cut through the use of a laser beam. This can be for small & fine materials or materials with a much greater level of thickness (e.g. metal sheets). The process simply involves the use of a focused laser beam (e.g. pulsed or continuous wave) to cut a wide range of materials to a high level of accuracy, using a process, which is highly repeatable.
The laser beam can easily be programmed to precision cut a diverse range of thicknesses and materials (e.g. metals (including reflective metals such as copper, silver and aluminium) – brass, tungsten, steel, pewter and titanium etc.), gemstones (e.g. diamonds), ceramics, graphic composites, silicon and many types of plastics.
