The Introduction of Laser Cutting Machine

Laser cutting Machine is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications.Laser cutting machine works by directing the output of a high power laser, by computer, at the material to be cut.The material then either melts, burns, vaporizes away, or is blown away by a jet of gasleaving an edge with a high quality surface finish.Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials. Advantages of laser cutting over mechanical cutting vary according to the situation, but two important factors are the lack of physical contact (since there is no cutting edge which can become contaminated by the material or contaminate the material), and to some extent precision (since there is no wear on the laser).There is also a reduced chance of warping the material that is being cut, as laser systems have a small heat-affected zone.Some materials are also very difficult or impossible to cut by more traditional means.One of the disadvantages of laser cutting includes the high energy required. There are three main types of lasers used in laser cutting machine.The CO2 laser is suited for cutting, boring, and engraving.The neodymium (Nd) and neodymium yttrium-aluminum-garnet (Nd-YAG) lasers are identical in style and differ only in application.Nd is used for boring and where high energy but low repetition are required.The Nd-YAG laser is used where very high power is needed and for boring and engraving.Both CO2 and Nd/ Nd-YAG lasers can be used for welding.
