now brings about multi rollers for the production of dimensionally precise, tubular hollow work pieces. The fixed roller housing of the CNC controlled machine can be eguipped with three, four, five or six rollers depending upon customer reguirements, including extremely large diameter part productions! Furthermore, Repkon is able to offer unigue flowforming solutions for very long parts, • extreme forming forces may be applied due to the robust body structure, closed- loop force transfer and negligible bending effects, • drive power can be fully transferred to the workpiece as slip-stick effect is totally eliminated due to roller-holder being a fixed part of the main frame, • full-load forming possible due to minimal vibration, • tailstock (headstock-2) that can be independently driven, and • adeguate number of tiltable CNC controlled support units that can be included for radial and axial support during forming.

FLOWFORMING – Can it really be a feasible production method? WHAT IS “FREE” FLOWFORMING? PART GEOMETRIES NOW POSSIBLE As a result of REPKON’s patented breakthrough, “free” flowforming, Through the use of a floating mandrel, friction between tooling and the workpiece may Using the “free” flowforming technology (Patent Registration No: 2 127 775), producing now be virtually eliminated, yielding free flow of material to achieve wall-thickness inner and outer cylindrical/conical/hyperbolical multi-contours, inner concave contours, reduction. The mandrel is, in fact, driven by the flowformed...
