Condition: new, Year of construction: 2025, machine/vehicle number: 1018, THE POWERFUL BENDING MACHINE FOR WORKSHOP AND ASSEMBLY. The compact and mobile bending machine enables precise and repeatable bending up to an outer diameter of 60 mm stationary and directly at the assembly site. A powerful three-phase motor and a precision gearbox provide a powerful drive. Optimum bending accuracy is achieved by position detection directly on the bending axis. The bending angle is set quickly and easily via a convenient, menu-driven user interface with touchscreen control, which guarantees even more intuitive operation. For more complex bending tasks, 100 bending programs can be stored, with an angle sequence of max. 8 bends per geometry. The multifunction control allows variable adjustment of the bending speed for forward and backward travel, and a parameterizable overbending function is provided to compensate for material springback. With the aid of the four material characteristics, the material is automatically overbent to the required bending angle, thus realizing an exact bending result. The "stationary tube and rotating tool" principle ensures low space requirements during bending. Sliding shoes are used for thin-walled tubes to achieve a wrinkle-free bending result and to bend bends with minimal deformations from e.g. stainless steel and copper tubes. With the PB20 profile bending attachment, flat, square and round bars can be bent without any problems.Extremely small bending radii are made possible with the KBV small bending attachment. POSSIBLE AREAS OF APPLICATION: - Plant engineering- Hydraulic piping - Meander bending- prototyping- Sanitary and heating construction TECHNICAL DATA: Bending capacity 6000S: Ø 6 to 50 x 4 mm alternating current 230 V Bending capacity 6000D: Ø 6 to 60 x 4 mm Bending capacity 6000DS: Ø 6 to 60 x 5 mm three-phase current 400 V Bending capacity 6000D: Ø 6 to 60 x 4 mm three-phase 400 V - Bending radius min/max: 36 mm/280 mm - Optional large bending radii up to 500 mm - Multifunction machine control Bending angle adjustment (0.1°) - Maximum bending angle 240 - Hexagonal shaft 40 mm for quick tool change - Safety foot switch with emergency stop - Weight 110 kg OPTIONAL ACCESSORIES: - Profile bender PB20 - for bending flat and square iron up to max. 100 x 10 mm, round iron up to max. 20 mm - Roller bender RB43 - The RB43 is placed on the 6-edge shaft of the bending axis.
