Hydrostatic Bearings in Coordinate Measuring Machines (CMM)

Key Takeaways:

Coordinate measuring machines need motion free of runout, vibration, and thermal drift. Hydrostatic guideways and spindles give CMMs the stable, repeatable motion their accuracy classes demand.

Гидростатические подшипники в координатно-измерительных машинах (КИМ)

Измерение требует идеала

Точность КИМ зависит от движения осей. Гидростатика убирает биение, ползучесть и дрейф пленкой.

Стабильные оси

Субмикронное биение, нет ползучести, демпфирование — путь щупа ровный. Масло уносит тепло.

Итог

КИМ на гидростатике дольше держат калибровку и реже требуют юстировки.

Ổ thủy tĩnh trong máy đo tọa độ (CMM)

Đo lường cần chuyển động chuẩn

Độ chính xác CMM phụ thuộc chuyển động trục. Thủy tĩnh bỏ biên, bò và trôi bằng màng dầu.

Trục ổn định

Submicromet biên, không bò, giảm chấn — đường đầu dò mượt. Dầu thoát nhiệt đều.

Kết quả

CMM thủy tĩnh giữ chuẩn lâu hơn, hiệu chuẩn ít hơn.

Paliers hydrostatiques dans les machines à mesurer (MMT)

Mesurer exige un mouvement parfait

La précision MMT dépend du mouvement des axes. L'hydrostatique supprime défaut, rampement et dérive par le film.

Axes stables

Défaut submicron, pas de rampement, amortissement—le trajet du palpeur est lisse. L'huile évacue la chaleur.

Résultat

Les MMT hydrostatiques gardent leur calibration plus longtemps.

Hydrostatische Lager in Koordinatenmessgeräten (KMG)

Messen verlangt perfekte Bewegung

Die MMT-Genauigkeit hängt von der Achsbewegung ab. Hydrostatik entfernt Rundlauf, Kriechen und Drift über Ölfilme.

Stabile Achsen

Submikroner Rundlauf, kein Kriechen, Dämpfung—der Tasterpfad ist glatt. Öl führt Wärme ab.

Ergebnis

MMT auf Hydrostatik halten die Kalibrierung länger und kalibrieren seltener.

Measurement Demands Perfect Motion

A coordinate measuring machine's accuracy is only as good as the motion of its probe-carrying axes. Any runout, stick-slip, or thermal drift injects error into every measurement. Hydrostatic guideways and spindles remove those error sources by floating axes on oil films.

Stable, Repeatable Axes

The non-contact oil film gives sub-micron runout, no low-speed crawl, and excellent damping—so the probe path is smooth and repeatable. Oil flow also carries heat away evenly, preventing the thermal drift that plagues mechanical guides.

Result for Metrology

CMMs built on hydrostatic axes hold their calibrated accuracy longer and across wider temperature swings, reducing re-calibration frequency and improving trust in measured data.
