This robust tube bending machine was developed for processing particularly complex bent parts with different tube diameters (3.2 to 12 millimetres) within a brake or fuel line and for tube lengths between 150 and 2,300 millimetres. The ERBM-LR can be freely programmed on three planes and can perform both left and right bending, draw bending and roll bending for each individual bending point. All movements are performed around the stationary tube.

This design is Dengler Tube Tec's response to the specific requirements of its customers in the automotive industry, who are dealing with increasingly complex brake and fuel lines made of steel or aluminium. "This patented new development has allowed us to plug a gap in the product range, because brake and fuel lines increasingly feature protective hoses with multiple tube diameters," says Norman Köchig, Head of Design at Dengler Tube Tec. The CNC single-head tube bending machine has nine NC axes and the standard model comes with numerous extras. Customers receive a completely ready-to-use bending cell.

In order to implement the new and multi-patented functional principle of the ERBM-LR, it was developed using the highest design and control technology standards. Where other machines are designed to move the tube in order to reposition the bending point, and sometimes even rotate the tube into position, with the ERBM-LR all translational and rotational positioning movements are carried out by the machine units themselves. This means there is no longer any need to consider the oscillation behaviour of the tube that is going to be bent while the positioning movement is underway. The longitudinal and rotational movements can be executed at the highest possible speed from the first to the last bend.
