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.)
Note that these are estimated costs based on assumptions of gas cost. Please contact us to request a specific application analysis

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.
