This clip opens on the working zone of a hydraulic shaft press. A stepped shaft rests on two V-blocks that slide along the bed to change the support span, and a contact probe rides the turning surface to mark where the bend peaks. The ram then travels to that exact point and delivers one short, metered stroke — point pressure rather than forcing the whole bar to bow.
Correction here is a loop, not a single blow: the probe reads the runout, the control works out where to push and how hard, the ram makes its stroke, and the same probe reads the shaft again before release. Parts that still read high get another targeted pass; parts inside tolerance roll free. The full routine is illustrated in our walkthrough of the straightening sequence.
It suits low-to-medium volumes of stiff parts — thick axle bars, piston rods, pump shafts and drill stems coming off heat treatment all straighten on the same bed. Frame style, support spacing and force are matched to the drawing rather than sold as a fixed spec. C-frame and gantry models for bars and tubes are shown on the hydraulic press page.
If manual straightening is eating shift time, send a part print and tolerance and we will estimate the cycle and recommend tonnage at no cost. Reach us through the contact page; PDF or DWG both work.
