Laser cutting, is a modern metal processing technology that uses lasers to cut metal into designed shapes. This technology is generally used by a computer numerical control of laser cutting machine. Laser cutting is a technique that uses lasers to cut materials, often for industrial manufacturing applications, but is also starting to be used by schools, small businesses and amateur. The principle of laser cutting is usually through the optical system to guide the output of high-power laser source. A laser optical system and CNC -LRB-computer numerical control are used to guide the material or produce a laser beam. A typical commercial laser used to cut a material involves a motion control system to follow the CNC or G codes of the pattern to be cut into the material. The focused laser beam points at the material, which melts, burns, evaporates, or blown away by the gas jet, leaving a high-quality surface finish edge. Industrial laser cutting machines are used for cutting flat plate materials as well as structural and piping materials.

CNC bending machine is equipped with the mold (general or special mold) will be cold under the metal plate bending into a variety of geometric cross-section shape of the workpiece. It is a sheet forming machine designed for cold-rolled sheet metal processing. It is widely used in sheet bending processing of automobile, aircraft, light industry, shipbuilding, container, elevator, railway vehicle and other industries.

Laser welding is a kind of welding method which uses focused laser beam as energy source to bombard the heat generated by welding parts. Because of the refraction and focusing optical properties of laser, laser welding is very suitable for the welding of micro-parts and parts with poor accessibility. Laser welding also has the characteristics of low heat input, small welding deformation, not affected by electromagnetic field and so on.
