Sąlyga: naujas, Gamybos metai: 2025, Track links for multi-blade saws are cast from high-quality cast iron or cast steel, which also ensures the high quality of the tracks produced. The links can be equipped with additional collecting spikes. The components forming the track chain—guides, pins, and bushings—are made from premium materials and are subjected to heat and thermo-chemical treatment for enhanced durability. Accurate feed pitch is achieved through a specialized hole-finishing process in the links. Upon request, we manufacture guides, breaking devices, sprockets, pulleys, and shafts. We design and produce tracks for multi-blade saws from all over the world for leading manufacturers such as: A.COSTA RAIMANN TOS SVITAVA REMA RESZEL Ledpfx Abowvp Ddjkjak GABIANNI PAUL OGAM as well as all models of CHINESE TRACKS.

Sąlyga: naudotas, Gamybos metai: 2023, Ex demo machine Garbsen CNC-CONTROLLED MACHINING CENTER Morbidelli m100 Drilling and milling made for you! This numerically controlled machining center is equipped with an extensive range of tools for milling and drilling to handle any requirement in the woodworking sector. Highly efficient – features drilling spindles with 8,000 rpm and the most robust spindle technology available on the market, offering more than 1,000 maintenance-free hours. Fully and extensively equipped – the vacuum pods can be individually configured via the TV FLEX worktable, allowing the machine to be adapted flexibly to your needs. User-friendly and intuitive programming thanks to integrated MAESTRO CAD-CAM CNC software. Easy to operate: the lowered machine base ensures the worktable is always accessible. The control cabinet and vacuum pump are integrated into the machine bed, and the PRO SPACE version requires no additional structural safety measures. Supporting structure The main frame consists of an exceptionally strong, monolithic steel base, heavily ribbed and extremely robust. Its especially wide support surface is specifically designed to provide the machine with outstanding stability, ensuring continuous precision under all working conditions. There is no need for the machine to be anchored to the floor. The base forms a large, solid foundation for the moving gantry: the operating unit is equipped with a balanced, stable and resistant support that withstands the highest loads, ensuring superior quality and greater accuracy. The moving gantry consists of a single solid piece bolted to the base and moves along prismatic guides with recirculating ball carriages of the highest quality. The machining unit is mounted on it and also moves along the Y and Z axes on prismatic guides with recirculating ball carriages. The movement of the lower moving unit (X-axis) and the machining unit along the traverse of the moving unit (Y-axis) is driven by a helical rack and pinion drive; this provides greater tooth-on-tooth thrust for higher acceleration and increased speed along the X and Y axes. The specially designed helical gearing ensures reduced wear on mechanical components and quieter operation. The vertical Z-axis is driven by a ball screw, delivering perfect balance under dynamic loads, and withstanding high acceleration and deceleration. The main milling unit is directly coupled with the Z-axis carriage, allowing for very high quality finishing with practically zero vibration. X-Y-Z axis movement is handled by brushless motors driven by static inverters. These provide: - Reduced cycle times thanks to improved acceleration - Improved positioning accuracy thanks to high-resolution encoders - Elimination of set-up operations when powering on the machine thanks to absolute encoders - No general maintenance on the drive system as the brushless system uses no brushes. The management of axis movement and general machine operations... Lodpfx Ajx A Dfgsbkjak
