Laser cutting<\/strong> is a metalworking process. It is available for sheets from 0.5 mm to 12 mm (aluminum) or up to 25 mm (steel) thickness. The size of the sheet metal is up to 1.5 x 3 m. The workpieces are cut from the sheet by a focused laser beam. In addition, a process gas (nitrogen or oxygen) is used, which protects the optics and blows the molten material out of the kerf. Most steels use oxygen as the process gas. An oxide layer is created on the cut edges, which has to be removed for some subsequent steps. In the case of stainless steels, galvanized steels and aluminum, nitrogen is used to blow out the kerf. The cut edge then does not oxidize. The price<\/strong> for a workpiece is made up of a share for the cutting time (depending on the material, thickness, cutting length, number of grooves), the material price and the fixed costs. If there are several identical workpieces, the fixed costs are only incurred once, i.e. the price per workpiece decreases considerably, depending on the geometry. <\/p>\n\n\n\n

Laser inscriptions<\/strong> are created by tracing contours with a low beam power. A tarnish engraving is formed through oxidation of the metallic surface: a colored, mostly brown, layer. This technology can be used to make markings for further processing steps in your own workshop, such as punch marks or assembly marks, as well as lettering or identification of the parts. Laser engravings are waterproof, smudge-proof and permanent, but there are no recessed structures, so they cannot be felt. <\/p>\n\n\n\n
