Laser Cutting Aluminum

Laser Cutting Application:
The aluminum dog tag shapes were cut out using a 2kW CW fiber laser (1080nm) with a focal length lens of 9 inches. The samples were processed using Nitrogen assist gas, an assist gas pressure of 280~300PSI, a nozzle diameter of 1.4mm and nozzle standoff of 0.5mm. In one pass, at 50% power, each dog tag was cut in 22mm/sec.

The application engineers recommend the Titan Series cutting machine for this process with a CW fiber laser (1060nm), 2kW power and a 9 inch focal length lens. The newest edition to Laser Photonics’ product line is the Titan Series. This machine is Laser Photonics’ first multipurpose fiber laser cutting machine with a single pallet shuttle table. It is equipped with a high-powered, energy efficient fiber laser and an advanced direct drive motion control platform. Comparable to other machines, the Titan has a lighter weight design and the fastest cutting speed on the market for comparable systems. This system offers ultra low power consumption allowing for the lowest operating costs among all laser types. The Titan’s fully software-controlled geometry alignment eliminates the need for special installation requirements. The Titan requires no optical system alignment, laser service or laser replacement parts making this system virtually maintenance free.
