AIR ASSIST CUTTING
For over 10 years, CINCINNATI has offered a process where clean, filtered, air is used as a substitute for the expensive nitrogen assist gas for both CO2 and Fiber lasers.The basis of this technology is the fact that air is approximately 80% nitrogen. The remaining components of air consist mostly of oxygen and some trace gases. The goal in this process is to maximize the beneficial effects of the 80% nitrogen component.
Compressed Air Part Quality
Stainless steel parts cut with air exhibit a bright edge with traces of straw color. Although some cosmetic parts cannot show any blemish whatsoever and would not be candidates for this process, most stainless parts used in assemblies can be cut with air assist. Similarly, most mild steel parts cut with air assist gas can be taken immediately to painting without the usual secondary operation of oxide removal. All CINCINNATI lasers come standard with parameters for air assist cutting for mild steel.

Air Assist Gas vs. N2 Assist Gas Hourly Cost Analysis
|Run Time||PSI @ Nozzle||Nozzle||SCFH||Hourly Cost|
|Air Assist Gas||19 min. 29 sec.||150||0.080 in.||896
(estimated @ $0.06/100 Cubic. ft.)
|N2 Assist Gas||19 min. 55 sec.||175||0.080 in.||1,032
(estimated @ $0.45/100 Cubic. ft.)

Requirements For Air Cutting
Supply requirements are different from the nozzle requirement because of losses at the filter and gas delivery piping. As with any laser process, confirm your application requirement with a CINCINNATI application specialist before making any purchases to support this process.
