回转定位精度 ±0.001 mm: How 静压 Tables Achieve It

Key Takeaways:

Marusaku hydrostatic rotary tables reach ±0.001 mm rotary positioning accuracy. The result comes from non-contact support, direct-drive torque motor, and closed-loop Heidenhain feedback working together.

Точность позиционирования ±0,001 мм: как её дают гидростатические столы

Что значит ±0,001 мм

Для φ630 это ≈±0,3 угловой секунды — нужно для многогранной обработки и деления.

Точность

Три фактора

Неконтактная опора (нет износа), прямой привод (без люфта), замкнутый контур Heidenhain RCN2380 (коррекция позиции).

Вместе

Убирают три источника ошибок: опору, передачу, измерение.

Применение

Оптика, нарезание зубьев, аэрокосмос, измерения.

🇻🇳 Tiếng Việt

Độ chính xác định vị ±0,001 mm: bàn thủy tĩnh làm được nhờ đâu

±0,001 mm nghĩa là gì

Với φ630 ≈±0,3 giây cung — cần cho gia công đa mặt và chia độ.

Độ chính xác

Ba yếu tố

Không tiếp xúc (không mòn), dẫn động trực tiếp (không chơi lỏng), vòng kín Heidenhain RCN2380 (hiệu chuẩn).

Cùng nhau

Xoá ba nguồn lỗi: đỡ, truyền, đo.

Ứng dụng

Quang học, cắt bánh răng, hàng không, đo lường.

Précision de positionnement ±0,001 mm : comment les tables hydrostatiques l'obtiennent

Que signifie ±0,001 mm

Pour φ630 cela fait ≈±0,3 seconde d'arc—nécessaire pour l'usinage multi-faces et le division.

Précision

Trois facteurs

Support sans contact (pas d'usure), transmission directe (sans jeu), boucle fermée Heidenhain RCN2380 (correction).

Ensemble

Élimine les trois sources d'erreur: support, transmission, mesure.

Applications

Optique, taillage d'engrenages, aéronautique, métrologie.

Drehtisch-Positioniergenauigkeit ±0,001 mm: wie hydrostatische Tische sie erreichen

Was ±0,001 mm bedeutet

Bei φ630 entspricht das etwa ±0,3 Winkelsekunden—nötig für Mehrseitenbearbeitung und Teilung.

Genauigkeit

Drei Faktoren

Kontaktfreie Lagerung (kein Verschleiß), Direktantrieb (ohne Spiel), geschlossener Kreis Heidenhain RCN2380 (Korrektur).

Zusammen

Eliminiert die drei Hauptfehlerquellen: Lagerung, Übertragung, Messung.

Anwendung

Optik, Zahnradfräsen, Luftfahrt, Messtechnik.

What ±0.001 mm Means

回转定位精度的±0.001 mm at φ630 mm table corresponds以an angular error的roughly ±0.3 arc-second. 该 level的repeatability为required用于multi-face machining与精度 dividing.

Rotary accuracy

Three Enablers

  • 无接触 静压 支撑去除 wear与cage error, holding geometry stable用于life.
  • 直驱 力矩电机(e.g., 485SJM-1350BH, 1350/2400 N·m) eliminates 齿轮/皮带 transmission error与反向间隙.
  • Closed-loop feedbackvia Heidenhain RCN2380 回转 encoder continuously corrects position.

为何 Together

Each alone helps; together they remove three main error sources—支撑, transmission,与measurement—so table holds ±0.001 mm run after run.

应用

光学 aspheric machining, 齿轮 切削, 航空航天 indexing,与精度 measurement all rely on 该 精度.
