Laser cutting machine using the action of high energy laser beam to the material to be processed, which absorbs the laser energy and melting occurs, steam ratio, the fracture phenomenon. So as to achieve the purpose of cutting materials. Laser cutting machine to meet the present laser using a field scale is the largest in industrial processes; high power CO2 laser and Nd:YAG laser mostly to laser cutting machine.

Advantage

Compared with other commonly used methods of cutting machine, laser cutting machine has the following advantages;

The 1 cutting quality.

(1) laser cut kerf narrow, can save raw materials,

(2) the slit good verticality, surface finish. No subsequent re machining and cleaning can be used for forming and welding;

(3) cutting edge, no burr, no mechanical stress. Small heat affected zone, no deformation

(4) laser cutting depth to width ratio. On the metal material can reach about 20:1, metal and nonmetal materials can reach more than 100:1.

The 2 cutting process

(1) the laser cutting speed. Low noise. Pollution-free.

(2) no "tool" wear in the cutting process, suitable for all materials
