Hydrostatic Ways and Guideways: Non-Contact Linear Motion

Key Takeaways:

Hydrostatic ways apply the same oil-film principle to linear axes, giving machine-tool carriages sub-micron straightness, no stick-slip, and infinite-life guidance.

Гидростатические направляющие: бесконтактное линейное движение

От вращения к линейному

Гидростатика применима и к линейным осям: масло в карманы вдоль направляющей несёт каретку без контакта.

Плюсы каретки

Нет износа, ползучести, высокая жёсткость, демпфирование — прямолинейность субмикрон и повторяемость без дробления.

Где важно

Сверхточное шлифование, измерение, крупные станки — там точность каретки решает.

Ray trượt thủy tĩnh: chuyển động tuyến tính không tiếp xúc

Từ xoay sang tuyến tính

Thủy tĩnh áp dụng cả trục tuyến tính: dầu vào hốc dọc ray nâng xe con không tiếp xúc.

Lợi cho xe con

Không mòn, không bò, cứng cao, giảm chấn — thẳng hàng submicrom, lặp lại không dừng.

Khi nào

Mài siêu chính xác, đo lường, máy lớn — nơi độ chính xác xe con quyết định chất lượng.

Glissières hydrostatiques : mouvement linéaire sans contact

De la rotation au linéaire

L'hydrostatique s'applique aussi aux axes linéaires: l'huile dans les cavités porte le chariot sans contact.

Avantages du chariot

Pas d'usure, pas de rampement, raideur, amortissement—rectitude submicron et répétabilité sans bruit.

Où ça compte

Mechlage ultra-précis, mesure, grosses machines—la qualité du chariot décide.

Hydrostatische Führungen: kontaktfreie Linearbewegung

Von Rotation zu Linear

Die Hydrostatik gilt auch für Linearachsen: Öl in Taschen entlang der Führung trägt den Schlitten kontaktfrei.

Vorteile am Schlitten

Kein Verschleiß, kein Kriechen, hohe Steifigkeit, Dämpfung—Submikron-Geradheit und Wiederholbarkeit ohne Rattern.

Wo es zahlt

Ultrapräzisionsschleifen, Messen, große Werkzeugmaschinen—dort entscheidet die Schlittenqualität.

From Rotation to Linear Motion

The hydrostatic principle is not limited to spindles and rotary tables—it extends to linear ways. Oil is pumped into recesses along the guideway, floating the carriage on a thin film so it slides without touching the rail.

Benefits on the Carriage

The film gives the same advantages as rotary hydrostatic support: no wear, no stick-slip at low feed, high stiffness, and oil-film damping. The result is sub-micron straightness and repeatable linear motion free of the crawl that limits ball or roller ways.

Where It Pays Off

Hydrostatic ways suit ultra-precision grinding, measuring, and large machine tools where carriage accuracy and long-term stability decide part quality. Marusaku applies the principle consistently across its hydrostatic product family.
