In this video a hydraulic long-shaft straightening machine handles oversized shafts on a heavy gantry frame. A traveling hydraulic press moves along the extended bed, multiple probes map bend over the shaft length, and sag compensation accounts for the part’s own weight — giving small-batch workshops a practical way to straighten long parts without expensive dedicated tooling. Oversized diameters and flanged ends are accommodated by the wide throat and open bed, and fixtures stay simple because the part family is typically varied.
The hydraulic ram delivers the high, controlled force needed for large-diameter alloy shafts, with press force and dwell set per program, while the measuring loop confirms each correction before the part moves. Machines run on 380–480 V three-phase power and scale to 1000-ton-class frames for the heaviest work. To choose the right architecture, see our comparison of hydraulic, CNC and fully automatic straighteners.
It suits job shops and makers of pumps, presses, rolls and heavy transmissions who straighten long shafts in mixed batches rather than millions of identical parts. Beds, supports and tonnage are engineered to order in the hydraulic straightening press series.
