Multi-Axis Digital Hydraulic Cylinder Precision Synchronization System

When the load requires substantial driving force or has a large surface area, multiple hydraulic cylinders are typically employed. In high‑precision actuation systems, achieving precise synchronous motion among these cylinders poses stringent requirements. In synchronization systems driven by synchronized motors, mechanical wear can lead to a gradual degradation of synchronization accuracy over time. Meanwhile, mechanically synchronized solutions that rely on ball screws and encoders often suffer from drawbacks such as non‑standard customizations, cavitation, and screw breakage in practical applications. To address these challenges, SCHWERLL adopts a digital servo‑valve‑based control scheme, integrating digital servo‑valve technology with high‑precision servo cylinders to build a stable, real‑time, multi‑cylinder, high‑precision synchronization system.
