What is Laser Cutting?

Laser cutting is a machining process that utilizes a high-powered laser to focus light into a narrow beam, which is then used to cut or engrave materials. This focused laser beam, usually generated by CO2 lasers or fiber lasers, heats and melts the material, creating precise cuts with minimal thermal distortion. The laser cutting machine controls the movement of the beam to produce intricate shapes and designs with high precision. This process is essential in industries where accuracy and quality are paramount, such as the production of stainless steel components and sheet metal fabrication.
