Ver tical or horizontal angle roll machine ERCOLINA ® has introduced the CE60H3 angle roll. Capable of bending a wide range of tubes, pipes and profiles, the CE60H3 angle roll model is designed to operate in either the vertical or horizontal position, with a maximum bending capacity of 3" schedule 10.

The included control tower with low voltage controls has a foot pedal for hands- free operation, and programmable touchpad controls with digital centre roll positioning on a remote pendant for increased repeatability. Memory storage offers eight individual programs and unlimited passes. A universal tool set is included for multiple profiles, and this model uses the same tooling as Ercolina’s CE50. The machine has a heavy-duty structure and rigid components for high section modulus ratings and reinforced engineered mainframe design. The CE60H3 features individual tie bar supports for each shaft to increase roll shaft rigidity and radii accuracy. The design increases distance between lower shafts and interaxes to accommodate a wider range of profiles. A larger hydraulic cylinder increases machine capacity.

Bending and cutting in a single step SCHWARZE-Robitec has expanded its cutting tool and has combined the bending and the final cutting of short bent tube components for large diameters of up to 76mm (3") in a single working step. To do this, the cutting tool is integrated into the bending tool. 100mm scrap accumulated for each part produced, depending on the bending system used. This high cost factor is reduced with the integrated cutting tool. Machining of longer pipe units instead of cut-off pipe sections is also possible thanks to the integrated cutting process. This also reduces the time required for loading and unloading the machine.

This makes the whole process more efficient, but was previously only possible for smaller diameters. The user benefits from a decrease in scrap material (up to 90 per cent) and reduced production times. The integrated cutting tool system is suited to the production of parts in large quantities, due to the material and time savings. Users in the automotive sector or the supplier industry are already using the system. To enable the advantages to be used with tube diameters of up to 76mm, Schwarze- Robitec has optimised the cutting tool. The tools can process these precise cuts in a short time. At the same time, the material savings can be high: previously, up to

With the new cutting technology, all components receive a clean cutting edge and can be immediately processed further. Therefore, this technology is particularly suitable for series production, for example, in the automotive sector or the supplier industry. This is where the savings of resources and time play an important role. The controlled chip removal process keeps most of the chips produced during the cutting process away from the machine. A prerequisite for integrating the technology into

all-electric machines of the high- performance series is the use of the CNC control NxG. The new controlling system enables cutting at any bending angle between 0 and 90° and is simply integrated into the bending program. The cutting tool processes all common materials – including aluminised steels or hard-to-cut materials such as chrome-nickel steels. Schwarze-Robitec, founded in 1903, is an international expert in the sector of tube bending machines. The company’s product range includes, in addition to tube bending machines and bending tools, tube perforating machines, measuring stations, and solutions in the area of special machinery construction.
