Laser Cutting Machine

Laser cutting is a technology that uses a laser programmed by a computer to cut materials, which is used in the production line and is typically used for industrial manufacturing applications.  Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.


Laser cutting can be complementary to the CNC/Turret process. The CNC/Turret process can produce internal features such as holes readily whereas the laser cutting process can produce external complex features easily.

Laser cutting machine takes direct input in the form of electronic data from a CAD drawing to produce flat form parts of great complexity. With 3-axis control, the laser cutting process can profile parts after they have been formed on the CNC/Turret process.

Function introduction:

The type of engraving laser cutter can be suitable to art gift, instrument operating panel, cup/medal, seal, press plate making, nameplate,fabric, leathe rornament, toy, advertisement, electron element, company logo, cutting of template, paper product, etc. The engraved pattern is very clear,good solid viewing,and the baseis as clean as a whistle.

The type of Cutting laser cutter can be suitable to nonmetal materials such as bamboo, putamina of coconut, paper, plexiglass, acrylic, marble, jade, crystal. etc. Its cutting quality Smooth cutting line and boder. High Precision and speed.  It suitable to cut materials, such as rubber, glass, acrylic, paper, plastic, bamboo, bone making, PVC, KT plate, leather, plexiglass, acrylic, marble, jade, crystal. etc. But particular materials must used at the guidance of Professional person. This laser cutter can be applied  to electron, grament industry, leather industry, furniture industry, decorating field, art gift field, advertising field, packing&printing, model field(building model, avigation&navigation model, wooden toy), industrial plate cutting, etc.

Types of Laser Cutting Machine:

There are three types of lasers. The CO2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and YAG is usually used for 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.

Important CO2 laser characteristics are high unsaturated gain, high-power output and good efficiency. It has been experimentally determined that gain is a strong function of tube diameter and that output power is essentially independent of diameter.
 
Typical neodymium (Nd) laser doping concentrations are of the order of 1 at. %. High doping concentrations can be advantageous e.g. because they reduce the pump absorption length, but too high concentrations lead to quenching of the upper -state lifetime e.g. via upconversion processes. Also, the density of dissipated power can become too high in high-power lasers. Note that the neodymium doping density does not necessarily have to be the same in all parts; there are composite laser crystals with doped and undoped parts, or with parts having different doping densities.

YAG laser is a four-level gain medium (except for the 946-nm transition as discussed below), offering substantial laser gain even for moderate excitation levels and pump intensities. The gain bandwidth is relatively small, but this allows for a high gain efficiency and thus low threshold pump power. It can be diode pumped or lamp pumped. It is a host medium with favorable properties, particularly for high-power lasers and Q-switched lasers emitting at 1064 nm.
