Laser cutting machine adopts laser processing, compared with traditional cutting, its advantages lie in high cutting precision, fast cutting speed, smooth incision without burr, flexible cutting pattern, and high cutting efficiency. A laser cutting machine is one of the most needed devices for industrial production. S&A chillers can provide a stable cooling effect for the laser cutting machine, and not only protect the laser and cutting head but also improve the cutting efficiency and prolong the use of the cutting machine.
