The new 25CNC-EMR R/L tube bending machine

while the digital drive mechanism increases the effectiveness of remote maintenance and boosts productivity. Furthermore, the new tube bending machine from Lang Tube Tec features an energy recovery system. When braking the processing axes, the freed- up energy is fed back into the system. The new control system is partly responsible for turbo-processing, among other things, and for the positioning of tube clamping and pressure die support with the help of an automatic set-up cycle. The automatically generated, optimal values are taken over directly in the bending program. Whenever the operator activates the bending program, values are automatically verified and, if necessary, fully automatically corrected before advancing to the production process. This means that retooling times are reduced to an absolute minimum. Maximum safety is guaranteed because as soon as a saved program containing all bending and setting parameters is activated, a simulation cycle is performed first at 10 per cent reduced speed. This test run eliminates accidental collisions that may be caused by the mounting of an incorrect tool. In addition to the increased production capacity through the coordination and simultaneous movement of the axes, the new 25CNC-EMR R/L from Lang Tube Tec also offers further optimisation. The software module saves time by anticipating movements and moving the machine into position for the next bending step. Pre-calculated positions can be assumed using dynamic limit switches, which also helps to prevent collisions. The new control system release also contains a wide range of maintenance and diagnosis functions. These can help to avoid downtimes using various help functions. Thanks to its intuitive control panel, the CNC-E series from Lang Tube Tec can even be controlled by operators without prior experience of CNC controlled machines.

per cent compared with conventional processing methods in which the bending head is fully rotated. “Thanks to the innovative machine design with its highly dynamic drives and the use of a completely new control system with Bend Motion Control, we have successfully optimised the bending cycles. As a result, the 25CNC-EMR R/L is not only one of the most flexible tube

GERMAN manufacturer Lang Tube Tec is offering a new fully electric tube bending machine with automatic change of bending direction with the new CNC- controlled 25CNC-EMR R/L. Thanks to the swivelling bending head and shifting of the clamping unit and pressure die support this innovative machine achieves short cycle times and can make time savings of up to 20

bending machines, but also one of the fastest in its class,” said Sabine Neff, sales director at Lang Tube Tec. Sectors such as the automotive or aerospace industries, which demand high output cycle times and maximum pro-

cessing precision, stand to benefit from the new innovation from Lang Tube Tec. The same applies to companies in the heating and air-conditioning sector. The 25CNC-EMR R/L is designed as a multi-stack and multi-radius machine that allows various radii to be bent in one setting, either in a rotary draw- bending or free-form bending process. With axial precision of ±0.05mm (transportation, clamping, pressure die support) and 0.05° (bending, rotation, swivelling), even the most complex bent components can be realised. The machine concept is based on a high machine rigidity, which is designed for maximum tube dimensions of 30 x 1.5mm, as well as on maximum operating comfort. This is achieved with an implemented loading and unloading function. The swivel-mounted collet rotation unit can remove the tube to be bent from a tube magazine and the swivelling bending head can place the finished component on the ground or on a conveyor belt. Since the 25CNC-EMR R/L is completely encased and even comes with an integrated switch cabinet, the new tube bending machine occupies very little space in production environments. Its design as a fully electric machine without hydraulic components ensures a lower error rate and minimum maintenance expenditure,
