Metal CNC Laser Cutting technology has revolutionised the sheet metal fabrication industry, and Rockpress has been at the forefront of this technology from the start. Our traditional laser cutters use nitrogen, oxygen and compressed air cutting technology, which provides complete accuracy, clean cutting and minimal heat residue. The maximum sheet size we can accommodate is 4000mm x 2000mm.
In 2017 we took delivery of a state-of-the-art TRUMPF TruLaser 3030 6kW Fibre Laser with RotoLas tube cutting attachment. This machine uses an optical cable as opposed to the traditional CO2 Lasers. The 3030 enables us to cut Copper and Brass and has a superior cutting quality and speed, in particular on lighter gauges. Another major advantage this machine has is in the cutting of Aluminium, the conventional CO2 lasers will generally leave dross (in particular on heavy gauges) on the cut edge which requires secondary work to remove. This new fibre laser will enable us to cut up to 25mm thick Aluminium with no secondary work required.
As all cutting instructions and patterns are saved to each machine’s computer memory, repeat work can be completed quickly and with accuracy that is identical to any previous work. The advantage of CNC Laser Cutting over Guillotining is in the finish. CNC Laser Cutting is clean and precise – leaving no burrs on edges and corners of the scored material. Rockpress can even incorporate a discreet radius into the process to completely eliminate sharp corners.
We can cut a variety of materials including Carbon steel, Mild steel, Stainless steel, Zinc Coated steel, Galvanised steel, Aluminium, Copper and Brass.
