Key Takeaways:
Diamond turning of infrared and optical components demands vibration-free, thermally stable rotation for nanometer surface form. Hydrostatic spindles are the standard foundation for these ultra-precision lathes.
Diamond-车削 Bar
金刚石车削 cuts infrared lenses, mirrors,与other 光学 elements采用 单一-crystal diamond tool, achieving nanometer-level surface form. 主轴 must be utterly free的振动与thermal drift or tool path为corrupted.

为何 静压 Is Standard
无接触 油膜 isolates 主轴 from floor与切削 振动,与oil flow 保持 temperature uniform—both essential用于nanometer form 精度. Sub-micron 径向跳动 ensures rotational symmetry optics require.
Outcome
静压 主轴 let diamond-车削 lathes hold surface与form 精度 该 infrared与visible-light optics demand, without wear与drift的mechanical 主轴.
