Year of construction: 2025, operating hours: 2 h, condition: new, functionality: fully functional, The universal laser marking system LAS 28 XL from Systemtechnik Hölzer GmbH can be used for a very wide range of marking applications. With the integrated fibre laser, you can mark almost all materials such as steel, hard metal, aluminium and plastics. Depending on the requirements, the system can be equipped with a 20, 30 or 50 watt fibre laser. For permanent marking, the use of the laser is necessary in many industries. With the powerful laser software, texts, numbers, 2D codes, QR codes and logos can be realised with just a few clicks and without extensive programming knowledge. The software automatically counts up serial and article numbers after prior setting. In addition, the software can read data (variable information such as drawing numbers, project designations, etc.) from existing tables and automatically transfer them to predefined areas. The use of a hand scanner is also possible. Bk3ky883 The standard equipment includes a laptop incl. holder with Windows operating system and laser software. Optionally, the laser model LAS 28 XL can be equipped with a rotary axis (3-jaw chuck) for marking cylindrical parts.
