Designed for round tubes, square tubes, rectangular tubes, open profiles, and special profiles. This laser cutting machine delivers maximum productivity, especially during production changeovers. The task: fiber laser up to 6kW for a wide range of metalworking applications. Unmatched Laser Cutting Performance High axis speeds and accelerations, paired with a stable mechanical structure, provide excellent cutting performance and accuracy. Lrodpfxjyh A Nye Af Sot The tube and profile laser processing machine for production — space-saving and simply smart! Innovative solutions 100% made in Saxony! Tubes and profiles from 15 x 15 to 160 x 160 mm 3D cutting with efficient fiber laser technology The semi-automatic 6-fold profile tube loading chain system enables fast job changeovers. With the optional bundle loader, you can work completely independently. Bevel Cutting A function that changes everything. With our machine’s ability to swivel its cutting head up to 50° on an additional fifth axis, we address one of the biggest challenges in modern profile machining. If the laser beam always strikes the tube perpendicular to the surface, the cut edge will be elliptical. Swiveling the tube laser’s cutting head, combined with the feed axis, enables true bevel cutting. With the skyTUBE Laser, you are always on the safe side! The skyTUBE Pro is a class 1 laser system — there is no risk of exposure to laser radiation or reflections during operation. For all our laser systems, safety and compliance with the highest standards and regulations are paramount.

The maxipack is an extremely reliable machine. Therefore, these machines are well-known in the chicken slaughtering industry for decades. The maxipack is made of stainless steel and high-quality, wear-resistant plastics. These ensure that the maxipack is able to continue to run for years in the production process after extensive mechanical, electrical and electronic revision. Moba M16 The Moba M16 taper machine is, suitable packing smaller chickens with a range of 900 to 1200 grams per chicken. - The machine consists of four protective covers with an interlock system that immediately deposits the machine when opened. In combination with the emergency stop, this ensures that the machine is safe to use. - Plastic bags can be easily changed by using the change function. This function ensures that the turntable rotates a quarter turn to ensure enough space to change the bags. - The compressed air system on this Maxipack is adjustable by means of a pressure reducing valve. The pressure reducing valve ensures that the moisture is filtered out of the compressed air. - The maxipack is also equipped with a pressure regulator, that ensures the maxipack to switch off if the pressure drops below 5 bar. Revision Moba M16 Maxipacks that arrive at Bos Technical Support are thoroughly cleaned before starting the revision. For the revision, original Moba high qualitiy components are used. Each maxipack is equipped with a new PLC (Program Logic Controller) that includes the latest software. The 8 pneumatic cylinders that this machine includes are all checked and replaced when necessary. The electrical cabinet is being rebuilt and provided with new wiring.
