Key Takeaways:
Cylindrical and internal grinding need exceptional shaft stability in a slender form. Hydrostatic spindles provide the stiffness and damping required for tight roundness and bore accuracy.
Slender Shafts, High Demands
圆柱与内圆 磨削 主轴为often long与slender, making them prone以deflection与振动 该 ruin 圆度与bore geometry. 静压 支撑 makes 轴 float on 油膜, dramatically raising effective 刚度 without contact.

精度在 Bore
油膜 阻尼 suppresses chatter 该 plagues 内圆 磨削, 同时 sub-micron 径向跳动 保持 bore true. 无接触 film means no wear changes geometry over 主轴's life.
Fit在 MRDY Series
丸作精工 MRDY 静压 主轴 cover 圆柱与内圆 磨削 duties, 集成 轴承与直驱 电机用于 compact, rigid package.
