Key Takeaways:
Marusaku hydrostatic spindles support both three-jaw chucks for rigid mechanical clamping and vacuum chucks for thin or delicate parts. Choose based on workpiece shape and material.
两 Proven Workholding Methods
A 精度 主轴为only as good as how it holds part. 丸作精工 静压 主轴 can be equipped采用 three-jaw chuck用于strong, repeatable mechanical clamping的solid workpieces, or vacuum chuck用于thin, fragile, or flat parts 该 jaw 会 distort.

Matching Chuck以Part
Use three-jaw chuck用于robust 圆柱 blanks 其中 grip force 至关重要. Use vacuum chuck用于optics, wafers,与thin discs 其中 uniform, non-distorting 支撑 protects form 精度—complementing 主轴's own 无接触 stability.
Consistency
Either way, 静压 film 保持 rotating 组件 stable, so clamping choice affects handling, not underlying 运动 质量.
