CNC bending machines have servo drives on all axes

Designed to reduce setup time and enhance production, CNC tube bending machines from Lang Maschinenbau GmbH & Co. feature electrical servo-drives on all axes and are available in single and multistack versions.

Multistack benders allow complex bending without tool change. If a multistack tool cannot be applied for stability reasons, an automated clamp die changing system that accommodates up to eight clamp dies is available.

The machines feature programmable bending procedures and boosting by the transport carriage, including boosting in the pressure die area. This boosting reduces wall thinning at the outer bend and allows narrow bends. A radius of less than 1 x OD can be achieved.

Other features include an MMI Mulitcontrol 2020 system; TFT monitor; touchscreen; plausibility verification; XYZ coordinate recalculation into bending parameters; flexible programming; multitasking; and 3-D displays. Remote maintenance and technology support are provided by an integrated modem and the Internet.
