Laser cutters are CNC machines that use a cutting head with a laser mounted on a gantry to cut large sheets of ferrous and non-ferrous metal. Though 2D lasers won’t work for all projects, anything flat or two-dimensional is ideal for this type of technology. Often 2D laser cutting is the first step in a process, as we can quickly cut complex shapes that later get stamped or go through a brake press to finish off the product.
At ATACO, we’ve invested in three state-of-the-art 2D fiber laser-cutting machines. With up to 6 kilowatts of power, these laser trimmers can process thicker materials and sheets as large as 79” (2010mm) x 161” (4100mm). The precise placement of laser beams creates consistent high-quality shapes. We utilize specific “parts nesting” software which optimizes material utilization and maximizes the number of parts made from a sheet of material. As a result, we decrease the amount of waste, while also reducing costs. In addition to increasing material utilization, we have an automated load and unload system, which decreases the time required for material exchanging. Parts and all scrap metal are automatically discarded afterward to clear off the machine and start processing a new sheet, increasing efficiency.
With both nitrogen and oxygen gas options, we utilize the best option to most efficiently complete your project. Whether your material is aluminum, galvanized steel, brass, copper, mild steel, stainless steel, or film protected stainless steel, we have the laser cutting equipment you need. We’ll choose the gas that best targets the specific characteristics you want during the process. Oxygen is an accelerant which requires less energy and makes for a quick process to cut up to one inch. It will react with the material cut out and produces an oxide on the edge that may require removal for paint adhesion. Using nitrogen, an inert gas, allows us to cut up to 1/4 inch, with no oxidation around the edges so there is no additional process needed if the part needs to be painted. With either option, we remove all debris generated to ensure consistency in the cutting process.
Laser trimming lends itself to low or high-volume projects. We regularly cut a few parts for a specific project you may have, to thousands of parts on a regular basis. “No one part lends itself better for us to cut, in particular,” says Joel Janssen, an engineering expert at ATACO. “We are able to target products and higher tolerances on material thicknesses that other companies may not be comfortable taking on.”
Whereas stamping requires new tooling for every part and prototype iteration, there are no expensive tooling costs with laser cutting. Design modifications are as simple as changing the CAD/CAM files and our CNC laser cutter takes care of the rest. This allows us to have fast turnarounds on your complex shapes and less development time.
