Features: Laser cutting can be extra hard, especially brittle and extremely soft materials, high melting point is difficult to machine materials; kerf width is very narrow; the cutting surface is smooth; cutting surface of the heat-affected layer of shallow surface stress; cutting speed, the heat-affected zone small; mechanical deformation, no tool wear, easy to automate production. Laser welding is laser focused into a very fine beam irradiation of high energy density to the workpiece so that the workpiece is heated melting, then cooled to a workpiece to get welding. Laser welding knot melting deep speed, high efficiency; laser welding burn narrow heat-affected zone is very small, a very small deformation of the workpiece, at the same time, the weld is small, precision welding; even welded structure, the product particles is very small , stomatal, mixed with few defects, mechanical properties, corrosion resistance and electromagnetic properties superior to conventional welding methods. The marketing department provides several programs for the promotion activity of green laser pointer .
Laser heat treatment is the use of high power density of laser beam on the metal surface treatment method. For example, when the metal surface is heated to just below the melting point of the critical transition temperature, the surface rapidly austenitizing and rapid self-quenching, the metal surface quickly be strengthened, namely, laser transformation hardening (laser hardening). Laser surface heat treatment techniques include laser transformation hardening technology, laser coating technology, laser alloying, laser shock processing, etc. These techniques change the mechanical properties of materials, heat resistance and corrosion resistance plays an important role. Different switches of green laser pointer have different functions.
Early laser drilling using a fixed-point shock method: pulsed laser beam in a position to keep processing until the hole. This processing method, processing of hole depth and aperture are restricted. After entering the practical stage, the YAG laser of high repetition rate the peeling hole drilling method (Trepanning), dedicated optical rotary head or CNC automatically generate the circular trajectory sets of laser material processing. This not only eliminates the limit of aperture, and auxiliary blowing Processing Zone was half open, melt more easily excreted, so the hole surface quality. A large number of parts of the same size holes for the distribution, especially rotary the development of flying punch (Drilling, on the fly), or a pulsed laser on a hole processing. The company is going to carry out the price-off sales of green laser pointer .
Holes are opened up, the workpiece take advantage of the rapid movement of the light pulse gap (move or rotate) to the next hole, so several cycles to several attacks on the same location until the completion of the processing of all holes.
