What Are Laser Cutting Machines?

Laser cutting machines are tools used in various industries for precision cutting and designing projects. They emit a high-powered laser beam to either cleanly cut or etch a specific design on materials such as steel, plastic, or wood. The beam can either burn, vaporize, or melt away the excess product, leaving a superior finished design or edge. These machines are often used in engineering for the precision cutting of components of machines and in industrial applications for cutting structural and piping materials and flat sheet material such as metal. They have settings known as computer numerical control (CNC), which control and direct the laser beam’s intensity for the desired design effect or specific cuts required in a manufacturing or design project. The laser beam is generated by a process where electrical discharges or a lamp trigger a lasing material within a confined container, causing a chemical reaction, resulting in a high-powered beam being released. The beam is then reflected using a mirror in a stream of monochromatic light, and from the mirror, the light is directed by fibre optics or mirrors to the work area, with the narrowest point of the beam cutting or making the design etch on the material1.
