The WITTENSTEIN alpha portfolio extends from Basic and Value segments to Advanced and Premium, covering the most diverse technical and commercial performance requirements. Manufacturers can thus implement their respective applications with a technically appropriate solution that also makes sound economic sense. J. Neu GmbH is an excellent case in point here: high quality and power density – expressed, among other things, as minimal torsional backlash, torsional rigidity, dynamics, torque and compactness – were the decisive parameters specified for the gearboxes for its 6-axis tube machining centers. The gearboxes chosen for this purpose – TP⁺, SP⁺ and TK⁺ in the Advanced Line and XPK⁺ in the Premium Line – ensure that tubes and profiles are bent on the machines with the highest possible dimensional accuracy in 2D and 3D.

Established in 1995 and at home in the small south-west German town of Grünstadt since 2001, its customers come from the automotive industry, refrigeration and heating, furniture making and numerous other sectors. 

Over the years freeform bending has emerged as the firm’s principal sales driver. In contrast to rotary draw bending, symmetrical and asymmetrical parts are not bent around a fixed die but pushed through a bending head. This results in gentler handling of the workpiece; although the wall thickness in the bends remains virtually unchanged, the bending process is much faster and more flexible with feed speeds of up to 300 mm/s. Almost all parts must be manufactured with the highest possible precision and tolerances are given in hundredths of a millimeter. To achieve such enormous forming accuracy, J. Neu puts its trust in gearboxes combining very low backlash with high torsional rigidity and torque density, so that highly reproducible bending shapes and highly available processes are guaranteed along with high dynamics, leading to short cycle times.
