Laser Cutting 6.25mm Thick Aluminum
Using a 2kW CW fiber laser equipped with a focal length lens of 9 inches and operating the system at 90% power, the samples were cut 10mm/second in one pass. The laser system used Nitrogen for assist gas. The assist gas pressure was 280~300PSI. The nozzle diameter was 1.4mm and the nozzle standoff: 0.5mm.
Following the completion of the cutting applications, Laser Photonics application engineers recommended the Titan cutting machine equipped with a focusing lens of 9 inches and a CW fiber laser (1060nm), 2kW for ¼” steel and aluminum. Should the customer desire to cut 1/8” copper, the recommendations are for a laser that is 5kW and up because it was not possible to cut through the copper as it requires a more powerful laser.

Laser Cutting Plastic (Polyethelene)Tube Sheets
The application engineers processed the samples using the SBM 1200 cutting system equipped with a 250W continuous wave CO2 (10.6 um) through a 2.5" lens. The plastic packaging was cut while fusing the cutting edge to form a bag. This process proved successful with the thinner 0.00128" material making the cut in 100mm/second and in just one pass. The material with a thickness of 0.005" required a more powerful laser than what was currently available in the lab. A 400-500 watt laser would be needed to fuse the ends of the thicker material while maintaining a manageable cutting speed. This process would require fixturing for the materials and some fume extraction to reduce the amount of residue caused while cutting/fusing.

Laser Cutting Plastic Sheets
In the second application, the previous process was duplicated with the number samples cut increased to seven to test the consistency across a number of samples. Again, the samples were processed using the SBM 1200 cutting system equipped with a 250W CW CO2 (10.6 um) through a 2.5" lens and according to the dimensions requested by the customer. The cutting speed and power used to cut the samples were chosen to optimize accuracy and edge quality.

Laser Cutting Sheet Alumin with Polyethylene Backing
Polyethylene is a thermoplastic commodity heavily used in consumer products, most notably the plastic shopping bag. Over 60 million tons of the material is produced worldwide every year. Shopping bags just scrape the surface of the uses of polyethylene. Manufacturers make various other everyday consumer products from polyethylene including: tables, chairs, and outdoor storage sheds. The medical industry, in particular, benefits from polyethylene when it’s applied as a backing on a sheet of aluminum and used to seal test tubes.
In this application, circles were cut from a sheet of aluminum with polyethylene backing which is used to fuse a series of tubes to the sheet. The circles were cut so that the tubes could be easily removed from the sheet without causing any damage to the tubes and maintaining the seal. The aluminum sheet with polyethylene backing samples were processed using a pulsed fiber laser (1064nm, 1mJ @ 20kHz) through scanning head and160mm focusing lens. The process took 3.24 seconds per hole and cut through in just one pass using 100% power.
The application engineers recommended a FiberTower™ marking system with a pulsed fiber laser (1064nm, 1mJ @ 50kHz) and a focal length lens of 160mm.

Laser Cutting Copper Sheet
Our application engineers recommend the Titan Series for these types of applications. The Titan Series 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. This system will achieve a level of quality and detail that is unprecedented in the industry for laser cutting. 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.

Laser Cutting Acrylic Panel Samples
The Laser Photonics application engineers made the following recommendations to the customer: The most appropriate system for this type of application is the SBM 1200 equipped with a 250 Watt continuous wave CO2 (106um) laser. A focal length lens of 2.5 inches should be used, depending on the focal distance requirements.
