Key Takeaways:
Turning benefits from high stiffness and low vibration at the cutting point. Hydrostatic turning spindles give 5–10× rolling-bearing stiffness with oil-film damping for better surface and roundness.
刚度 at Cut
In 车削, chatter与poor 圆度 often trace back以 compliant 主轴. A 静压 车削 主轴提供5–10× 刚度的 滚动-轴承 design, resisting deflection under 切削 force.

平稳, Repeatable 回转
油膜 damps 振动 at source与保持 轴 无接触, so 径向跳动 stays 不超过 0.1 μm与low-speed operation为爬行-free. MRDY 静压 车削 主轴 can be paired采用 three-jaw chuck or vacuum chuck depending on workpiece.
Outcome
Better 圆度, finer 表面粗糙度,与consistent 结果 from first part以 last—without 轴承 wear changing process mid-life.
