PCB materials with residual web connections can be rapidly and economically separated up to a maximum size of 320 mm x 560 mm. The separation process is servo-controlled across all axes, with the milling spindle operated from above. The highlight of the machine is the ability to switch the working area from a small format (320x280 mm) to a large format (320x560 mm) thanks to its simple and straightforward operation. • Short cycle times thanks to shuttle operation • X/Y axes with linear motor technology Lrodoxmfdxspfx Alksk • Panel fixation using pin technology • Flexible handling • Suitable for PCBs with remaining web connections • Servo-controlled milling spindle adjustment • Extraction device • Easy operation • Excellent price-performance ratio Manual depaneling – flexible and cost-effective The manual depaneling concept offers substantial advantages in terms of flexibility and cost. Medium production volumes can be quickly and low-dust separated with the LOW MINI. The standard configuration includes dual loading with linear motor technology; for expanding the working area, single shuttle operation is possible. User and service friendliness, combined with outstanding price-performance, ensures convenient operation and makes investing in this depaneling machine economically attractive. Axis speed: 160 mm/s Repeatability: 0.02 mm Separation accuracy: 0.1 mm Shank tool: 0.8 - 2.4 mm

Tahun pembuatan: 2026, Kondisi: baru, Fungsionalitas: berfungsi sepenuhnya, Semi-automatic depaneling / Base unit with parallel shuttle The dynamic depaneler LOW 4322 XL is specifically designed for medium to high product volumes and meets the increasing demands of modern production processes.

Tahun pembuatan: 2025, Kondisi: baru, Fungsionalitas: berfungsi sepenuhnya, nomor mesin/kendaraan: LAS 23 mit integrierter Absaugung, The LAS 23 portable is a compact and mobile fiber laser designed for flexible direct marking of a wide variety of workpieces directly at the place of use. Thanks to its rollable base frame, the system can be deployed independent of location and can be easily moved to hard-to-reach or large-volume workpieces. This makes it especially suitable for applications where a stationary laser cell is not practical. The modular design with customized attachments allows for rapid and tool-free adaptation to different workpiece geometries. The quick-change system enables fast replacement of attachments—ideal for varying marking tasks in production and maintenance. The integrated laser software supports the creation of texts, serial numbers, 2D codes (e.g., DataMatrix, QR codes), and graphic elements (e.g., logos) via a user-friendly interface, which can be operated without programming knowledge. Serial and article numbers can be incremented automatically. In addition, there is the option to import variable data—such as drawing numbers or project identifiers—from external tables (e.g., CSV/Excel files) and automatically integrate them into the marking template. Optionally, a handheld scanner can be connected for fast data acquisition, reducing manual input and increasing process reliability.
