Key Takeaways:
A representative precision grinding case shows how a hydrostatic spindle's sub-micron runout, stiffness, and oil-film damping translate into consistent mirror finishes and stable accuracy over long batches.
Challenge
精度 磨削的hard, tight-tolerance parts demands 振动-free 回转与thermal stability. Conventional 主轴 introduce 径向跳动, stick-slip,与heat 该 limit finish与geometric 精度,与they wear—drifting process over time.

静压 Solution
A 静压 磨削 主轴 floats 轴 on 3–50 μm 油膜采用径向跳动 不超过 0.1 μm, 刚度 above 500 N/μm,与油膜 阻尼. film carries heat away evenly与never wears.
Outcome
Operators see consistent mirror finishes与held tolerances from first part以 last在 long batch. Because 精度 does not degrade采用use, first-article与in-process qualification stay valid, 切削 scrap与rework.
