Selecting a hydrostatic rotary table means matching load capacity, positioning accuracy, speed range, and table diameter to your process. Learn the key criteria and how Marusaku's MRDY series covers them.
Учтите вес детали с приспособлением с запасом. Стол φ630 мм несёт 1000 кг при 3,5–4 МПа. Подберите диаметр по габариту.
Гидростатика даёт ±0,001 мм. Энкодер замкнутого цикла (Heidenhain RCN2380) подтверждает точность.
От сверхнизких оборотов без ползучести до десятков тысяч об/мин. Прямой привод 485SJM-1350BH (1350/2400 Н·м) даёт момент без ремней.
MRDY-630/500/465 перекрывают диапазоны нагрузок.
Tính cả đồ gá với dự phòng. Bàn φ630 mm chịu 1000 kg ở 3,5–4 MPa. Chọn đường kính theo kích thước phôi.
Thủy tĩnh đạt ±0,001 mm. Encoder vòng kín (Heidenhain RCN2380) xác nhận.
Từ rất thấp không bò đến hàng vạn vòng/phút. Trực truyền 485SJM-1350BH (1350/2400 N·m) không cần đai.
MRDY-630/500/465 phủ các mức tải.
Comptez la pièce plus le serrage avec marge. La table φ630 mm porte 1000 kg à 3,5–4 MPa. Choisissez le diamètre selon la pièce.
L'hydrostatique atteint ±0,001 mm. Un codeur fermé (Heidenhain RCN2380) la vérifie.
De très basse (sans rampement) à des dizaines de milliers de tr/min. Entraînement direct 485SJM-1350BH (1350/2400 N·m) sans courroie.
MRDY-630/500/465 couvrent les plages de charge.
Bestimmen Sie Werkstück plus Spannmittel mit Reserve. Der φ630-mm-Tisch trägt 1000 kg bei 3,5–4 MPa. Wählen Sie den Durchmesser passend zur Aufspannung.
Hydrostatik erreicht ±0,001 mm. Ein geschlossener Encoder (Heidenhain RCN2380) verifiziert sie.
Von sehr niedrig (ohne Kriechen) bis Zehntausende U/min. Direktantrieb 485SJM-1350BH (1350/2400 N·m) ohne Riemen.
MRDY-630/500/465 decken Lastbereiche ab.
Start with the heaviest workpiece plus fixture, then add margin. Marusaku's representative φ630 mm table carries 1000 kg at 3.5–4 MPa oil pressure. Match the table diameter to your part envelope and machine envelope.
Hydrostatic tables reach ±0.001 mm rotary positioning. Pair the oil film with a high-resolution closed-loop encoder—such as the Heidenhain RCN2380—for verified, repeatable accuracy.
Hydrostatic support works from very low speed (no crawl) to tens of thousands of rpm. A direct-drive torque motor (e.g., 485SJM-1350BH, 1350/2400 N·m) gives high torque at low speed without belts or gearboxes.
The Marusaku MRDY series—MRDY-630, MRDY-500, MRDY-465 and more—spans diameters and load ratings so you can select the right foundation for grinding, turning, or five-axis machining.
