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,the prospect of laser cutters for sale is very good.
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,the prospect of laser cutting machine for sale is very good.
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, average diameter of blasting perforation thickness of the half, so the blasting perforation aperture is bigger, thicker plate and not round, shoulds not be used on demand higher parts (such as oil sieve tube), can only be used for waste.In addition due to perforation of oxygen to the same pressure and cutting, splash is bigger.
Laser cutting machine is the use of the laser beam is emitted from the laser generator, the light path system, focus on high power density laser irradiation conditions, laser heat absorbed by the workpiece material, workpiece temperature rise sharply, arriving at boiling point, the material began to boil and forming holes, accompanied by high pressure air flow, with the movement of the relative position between the beam and workpiece, eventually to form material cutting seam.When cutting seam process parameters (cutting speed and laser power, gas pressure, etc.) and trajectories are controlled by CNC system, cutting seam and slag is a certain pressure of auxiliary gas blowdown,the prospect of laser cutter machine for sale is very good.
