The video shows an automatic hydraulic straightening machine: a high-force hydraulic ram does the pressing, while CNC measurement and control decide where, how far and how often — combining the force and toughness of hydraulic construction with the repeatability of automatic measure-and-correct cycles. It suits factories that already rely on hydraulic presses but need consistent, measurable results across different operators and shifts.
After each stroke the probes re-read runout and the controller compensates springback, so hardened and alloy shafts converge on 0.02–0.05 mm TIR without trial-and-error pressing. Frames run from compact C-types to gantry structures up to 1000-ton-class, on 380–480 V three-phase power. To see where this hybrid fits, read our comparison of hydraulic vs CNC vs fully automatic straighteners.
It is the practical middle ground for plants straightening medium and large shafts — axles, pump shafts, transmission and machinery shafts — in recurring batches: faster than a plain hydraulic press, simpler than a robotic line, and its rugged hydraulic unit holds up well to heavy three-shift workshop duty with straightforward routine maintenance. Frame options are listed under the hydraulic press series.
