With the integrated fiber laser, you can mark almost any material, such as steel, carbide, aluminum, and plastics. Depending on requirements, the system can be equipped with a 20, 30, or 50 watt fiber laser. In many industries, the use of a laser for permanent marking has now become essential. The powerful laser software enables texts, numbers, 2D codes, QR codes, and logos to be generated with just a few clicks and without extensive programming knowledge. Serial and part numbers can be automatically incremented by the software after initial setup. Furthermore, the software can read data (variable information such as drawing numbers, project designations, etc.) from existing tables, and automatically transfer it into predefined fields. The use of a handheld scanner is also possible. Standard equipment includes a laptop with holder, Windows operating system, and laser software. Optionally, the LAS 28 XL can be fitted with a rotary axis (3-jaw chuck) for marking cylindrical parts. Further options, such as lateral extensions for marking long parts, motorized Z-axis, drawer systems, etc., are available.
