There are several kinds of laser cutting machine punch

Laser cutting machine is a laser beam to the surface to the energy released when the workpiece melting and evaporation, to achieve the purpose of cutting and carving, has high precision, fast cutting, cutting pattern is not limited to, automatic typesetting save materials, incision smooth, low processing cost etc, will gradually improve or replace the traditional metal cutting processing equipment. There are several kinds of laser cutting machine punched way?
1, pulse perforation: the peak power of pulse laser make a small amount of material to melt or vaporize, commonly used as auxiliary air or nitrogen gas, to reduce the make hole expansion with exothermic oxidation, gas pressure is cutting the oxygen pressure is small. Each pulse laser to produce only a small particle injection, gradually thorough, so thick plate punch time takes a few seconds. Once the perforated completion, auxiliary gas into oxygen cutting. This perforation diameter smaller, the perforation quality is better than that of blasting hole. For the use of laser should not only have high output power; More important in time and space characteristics of beam of light, so the general crosscurrent CO2 laser can't adapt to the requirement of shenzhen laser cutting machine. Pulse perforation also need to have a reliable pneumatic control system, so as to realize the switch of the gas type, gas pressure and aperture time control. In the case of using pulse perforation, in order to obtain high quality of incision, from workpiece resting pulse perforation to the transition of workpiece speed continuous cutting technology should take seriously.
2, blasting perforation: material after continuous laser irradiation in the center of the formation of a pit, and then by coaxial laser beam with oxygen flow quickly remove the molten material into a hole. General hole size and thickness, half of the average diameter to thickness, blasting perforation for thicker plate blasting perforation aperture is bigger, and do not round, unfavorable use (on demand higher parts Such as oil sieve tube) And can only be used for waste. In addition due to perforation of oxygen to the same pressure and cutting, splash is bigger.
