Precision and hydraulic force rarely share a frame, which is what this footage sets out to show. A long shaft turns on its supports, the probe maps it in fine detail, and a guided ram corrects it under tightly controlled pressure — stroke length metered, dwell timed, re-check automatic. The welded gantry holds geometry while the valve work holds finesse, stroke after stroke.
The results tier like any precision process, top grade first: ≤0.02 mm TIR for spindles and instrument work, the 0.02–0.05 mm band for automotive shafts, and 0.10–0.30 mm/m for general mechanics. Holding the top band on a hydraulic machine comes down to frame rigidity, probe resolution and springback prediction working together; the prediction side is covered in the compensation guide.
Typical work is demanding long product — precision lead screws, spindle shafts, printing rollers and hydraulic cylinder rods where the surface cannot afford a mark, with V-blocks and contact points positioned to protect finished journals. The bed and supports are sized for the longest, most delicate part in the family. Precision hydraulic configurations are shown on the hydraulic straightening press line page.
