The distinctive feature in this video runs the full length of the bed: a row of measuring probes instead of the usual one or two. As the shaft rotates, every probe reads its own section at the same time, so a long part that would need repeated repositioning on a conventional press is mapped in a single pass, with the deflection curve drawn across the whole length.
Short shafts are captured at 2–3 points, but long-bed versions carry 5–8 probes or more, and the control uses that dense data to sequence the ram section by section — correcting a bend in one zone without chasing the movement it causes in the next. The scanning, stitching and correction logic is part of the sequence overview.
It is the right tool for genuinely long, slender work — printing and conveyor rollers, lead screws, long piston rods and tubular axles where a bend can hide between sparse checkpoints. Bed length, probe count and frame force are specified from the parts, and long workpieces stay supported between probe stations throughout the cycle. Long-bed hydraulic configurations appear on the bar and tube press range.
If your parts are long and your checkpoints feel sparse, send a drawing and we will recommend probe count and bed length from the geometry, free of charge. Contact the Shangda team.
