Laser cutting is a process in which a item is cut from sheet metal workpiece with a laser in a CNC machine, i.e. a laser cutter. A laser cutter can work in many different materials such as steel, stainless steel, aluminium and other metals as well as in many non-metallic materials. A laser cutter is programmed directly from a digital file (draft), and the changeover from one item to another is therefore very fast. A modern laser cutter with high capacity works efficiently and precise.
KK Metal offers laser cutting with automatic material intake. This means that laser cutting can be done unstaffed, and thereby, cost-effectively. KK Metal has experience with laser cutting in all common steel qualities, stainless/acid-resistant steel, aluminium and metals in various levels of thickness.
Laser cutting – a very flexible method
Laser cutting is undoubtedly the most flexible and common method of sheet metal cutting in the iron and metal industry, when producing singular and small to medium batches. As a relatively new technology, laser cutting is still in rapid development. Whereas you 15-20 years ago could only cut in thin plates, typically up to a maximum of 5-6 mm steel, today you can cut in up to 20 mm.
A laser cutter is characterised by being able to cut any form or shape and fast in changeover, both in terms of the shape of the item, but also regarding material type and thickness.
In principal you can do laser cutting in all materials. However, not all types of material are equally suited for laser cutting. E.g. materials with high thermal conductivity (aluminium, copper and certain others) require more power, and therefore, you cannot cut in the same thickness as, e.g. in steel.
A laser cutter is programmed, by inputting the digital draft (often a dxf file) in an appertaining program, and thereby, the laser’s cutting path and other parameters are generated from the draft/dxf file. This means that you can generally take a 3D drawing, unfold it, and from this generate the dxf file. A very reliable and efficient method, you avoid error, and the programme can be generated very fast.
