Key Takeaways:
The MRDY-500 brings the same hydrostatic direct-drive principle to a smaller φ500 mm platform—ideal where space is tight but sub-micron rotary accuracy is still required.
Scaling 静压 Principle
MRDY-500 applies same 液体-静压, 直驱 concept as MRDY-630 but on more compact φ500 mm worktable. 油膜 still fully 支撑 table, so 精度与阻尼为preserved at smaller footprint.

为何 Choose 500
When 机床 envelope or part size does not need φ630 mm, MRDY-500带来identical 无接触 benefits—sub-micron 径向跳动, no 爬行, 无限寿命—同时 fitting tighter installations与reducing oil-supply volume.
Shared DNA
Like rest的 MRDY series, 500使用membrane-feedback or comparable high-刚度 restrictors, 直驱 力矩电机,与closed-loop encoder feedback用于verified 精度.
