The basic principle of laser cutting machine whether you understand it?
Shanghai Chong Ming Laser Equipment Co., Ltd. main products are laser cutting machine, CNC engraving machine, large-scale drilling and milling machine (heavy industry), wood molding machines, engraving and milling machines, plasma cutting machine, laser marking machine and small engraving machine, CNC machinery and equipment . With advanced production technology and years of innovation efforts, we have greatly improved the design and production equipment to ensure that products are more reliable, more accurate, more durable and achieve a high level of low energy requirements.
Laser is a light, and other natural light, is made of atoms (molecules or ions) transition generated. But it is different from the ordinary light in the first laser only a very short time depends on the spontaneous emission, the subsequent process is completely determined by the stimulated emission of radiation, and therefore the laser has a very pure color, almost no directional divergence, high luminous intensity and high coherence.
Laser cutting is high power density energy generated laser focused to achieve. Under the control of the computer, the laser pulse discharge, so that the output frequency of the controlled high repetition pulsed laser, a certain frequency, a certain width of the beam, the pulsed laser beam through optical transmission and reflection and focused by the focusing lens group Processing on the surface of the object, forming a fine, high energy density spot, focal spot is located near the surface to be processed, to instantaneous high temperature melting or vaporization material to be processed. Each laser pulse instantly put a high surface energy of sputtered a small hole, under computer control, laser processing head and the workpiece material at a pre-painted good graphics for continuous relative motion RBI, putting objects such as machining desired shape.
Process parameters (cutting speed, laser power, gas pressure, etc.) when the slit and trajectory by the CNC control system, slag slotted at constant pressure by the auxiliary gas blowing.
