 Laser cutting machine theory 
 Laser cutting is laser focused energy to achieve high power density. Under the control of the computer, through pulsed laser discharge, in order to repeat the high-frequency pulsed laser with output controlled to a certain frequency, a certain pulse width of the beam, the pulsed laser beam through the optical transmission and reflection and through the focusing lens group to focus on the processing of objects on the surface, forming a fine, high energy density spot, the spot diameter is generally 0.1 ~ 0.4mm, located in the focal spot to be processed near to the instant high temperature melting or gasification processing materials. A high-energy laser pulse instantly put a small hole surface sputtering, under computer control, the continuous relative movement dot laser processing head and the material being processed by the pre-painted graphics, object processed into the desired shape. Cutting, wave and beam coaxial airflow emitted from the cutting head, blow melting or gasification of the material from the bottom of the incision (Note: If the gas blowing and cutting material thermal efficiency response, this response will provide cutting The additional energy required; airflow cooling the cutting surface, reduce the heat-affected zone and to ensure the role of the focusing mirror is not contaminated). Compared with the traditional plate processing method, the laser cutting with a high cut quality (narrow kerf width, the heat affected zone is small, smooth incision), high cutting speed and high flexibility (can be cut any shape), a wide range of materials to adapt of the advantages. 

 Characteristics of the laser cutting machine 
 Speed, small deformation; 
 Kerf quality and appearance of smooth, beautiful, without the order processing; 
 The laser beam is easy to realize the spectrophotometric time and space, at the same time processing of multi-beam and multi-task processing; 
 Cleavage of pollution-free, heat should be taken small; 
 Simple operation, high precision cutting. 

 Industrial applications 
 Co2 laser cutting machine is mainly used for wood processing, packaging, printing, craft jewelry, advertising, decoration, building models, simulation models, leather clothing, electronics industry, die-cutting plate manufacturing and sheet metal processing industries, cutting and engraving wood, paper, rubber, leather, acrylic, plastic, ceramic, fabric fiber composite and sheet metal materials can also be carved horns, color plates, paint, copper, aluminum, glass and stone materials.
