Laser Cutting Gas Nitrogen Generator Mixed Gas Generating System for Laser Cutting Machine

Fine Cutting (Mixed Gas Cutting)System

Mixed gas cutting employs a specific ratio of nitrogen-oxygen mixture as the laser assist cutting gas, leveraging the advantages of each component gas (nitrogen for high-speed cutting and oxygen for burr-free cutting) by combining them into a single cutting stream. This method enables rapid cutting with minimal burrs, significantly improving the cutting quality for medium-to-thick low-carbon steel and aluminum alloys while achieving higher cutting speeds than pure nitrogen. The burring issues encountered when using pure nitrogen or air cutting are minimized or eliminated.

Advantages of Mixed Gas Cutting  

● Improves cutting quality for ordinary steel, reducing burrs to <3% of material thickness;  

● Higher surface finish compared to air cutting;  

● Significantly increases cutting speed compared to high-power oxygen cutting for medium-thick carbon steel plates;  

● More cost-effective compared to liquid nitrogen cutting.

Product Introduction

The Fine Cutting Prime Series adopts medium-pressure dual-tower PSA (Pressure Swing Adsorption) filtration technology, which is the industry gold standard for nitrogen generation through air separation, capable of delivering clean, dry, and particle-free nitrogen on demand. We utilize high-quality carbon molecular sieve materials with superior nitrogen-to-air ratio to achieve long lifespan and high-efficiency nitrogen production. The exclusive SMART-REIN intelligent reinforcement control is designed to meet the demands of high-output factories, suitable for prolonged operation or unattended cutting scenarios. This system can produce nitrogen-oxygen mixed gas as needed and reliably provide auxiliary gas support during instantaneous peak flow cutting requirements.
