Laser cutting machine cut hole

Laser cutting machine to cut punch skills: any kind of eager to open skills, in addition to a few conditions can from the beginning of plate marginal, normal should be a small hole on the plate. The laser punching compound machine is to use the punch first before first rushed out of a hole, then cut by laser from small beginnings. Laser cut on no stamping equipment boot the fundamental way: there are two types of perforation pulse perforation - — Choose the peak power of pulse laser melt a few data or vaporization, commonly used air or nitrogen as for gas, to cut make hole expanding with exothermic oxidation, gas pressure is cut the oxygen pressure is small. Each pulse laser only small particles of eruption, deepen gradually, so thick plate perforation moment needs a few seconds. Once completion of perforation, vertical line for gas with oxygen for open. This perforation diameter smaller, the perforation quality is better than that of blast hole. Not only for the use of laser should have high output power; More important moment of beam of light and space characteristics, pulse perforation also need to have a strong pneumatic control system, with complete varieties, gas pressure switch and perforation moment control. Blast hole - — Data after laser shines in a row that constitute a pit in the middle, and the oxygen flow with coaxial laser beam will soon be molten material removed form a hole. Usually hole intrusive related to thickness, blast hole even half of diameter to thickness, so for the thicker plate explosive perforation aperture is bigger, and do not round, should not be used on parts machining precision demand is higher, can only be used for waste. In addition because of perforation used oxygen pressure and cut, splash is bigger.
