Key Takeaways:
Optical mirrors need nanometer-form accuracy. A hydrostatic rotary table's vibration isolation, thermal stability, and ±0.001 mm positioning make it the right foundation for aspheric and parabolic mirror work.
Challenge
Non-spherical 光学 elements—aspheric lenses与parabolic mirrors—require form 精度在 nanometer range. Any 主轴 or floor 振动,与any thermal drift, corrupts surface during 金刚石车削 or 磨削.

静压 Solution
A 静压转台 floats workpiece on 3.5–4 MPa 油膜, isolating it from 振动采用油膜 阻尼与keeping temperature stable through oil flow. 丸作精工 tables reach ±0.001 mm 回转 定位采用an air-curtain seal protecting clean film.
Outcome
光学 substrates为cut采用consistent nanometer-级 form与excellent repeatability. 无接触 film 去除 径向跳动, 爬行,与thermal error 该 limit conventional tables—enabling true 精度 optics.
