Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the quality of the workpiece. Modern laser has become people’s fantasy pursuit of “cutting iron as mud” “sword”. Business parthers CO2 laser cutting machine, for example, the whole system consists of control system, motor system, optical system, water system, smoke and gas blowing and other components of the system, adopts the most advanced numerical control mode to realize multi-axis linkage and cutting energy, such as the laser is not affected by the speed at the same time support DXP, PLT, CNC and other graphic formats and strengthen interface graphics processing power; Imported servo motor with superior performance and drive guide structure to achieve good motion accuracy at high speed.
Laser cutting is achieved by using the high power density energy generated after laser focusing. And controlled by computer, through the pulse laser discharge, thus the output controlled repeated high frequency pulse laser, the formation of a certain frequency, pulse width of the beam, the pulse laser beam through the light path transmission and reflection and through the focusing lens group focused on the machining surface, forming a subtle, high energy density, intensity, focal spot near to processing surface, To melt or vaporize the processed material at an instantaneous high temperature. Every high energy laser pulse instantly sputtered out a small hole on the surface of the object, under the control of the computer, laser processing head and be processed material according to the pre-drawn graphics continuous relative movement dot, so that the object will be processed into the desired shape. When cutting, a coaxial airflow with the beam is ejected from the cutting head, and the molten or vaporized material is blown out from the bottom of the cut (note: if the blown gas and the material to be cut produce a thermal reaction, this reaction will provide additional energy required for cutting; Airflow also has the function of cooling the cut surface, reducing the heat affected zone and ensuring the focus lens is not contaminated. Compared with the traditional plate processing method, laser cutting has the advantages of high cutting quality (narrow incision width, small heat affected zone, smooth incision), high cutting speed, high flexibility (can be cut arbitrary shape), wide material adaptability.
