Key Takeaways:
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.
Define Your Load与Size
Start采用 heaviest workpiece plus fixture, then 增加 margin. 丸作精工's representative φ630 mm table carries 1000 kg at 3.5–4 MPa oil pressure. Match table diameter以your part envelope与机床 envelope.

精度与Feedback
静压 tables reach ±0.001 mm 回转 定位. Pair 油膜采用 high-resolution closed-loop encoder—例如 Heidenhain RCN2380—for verified, repeatable 精度.
Speed与Drive
静压 支撑 works from very low speed (no 爬行)以tens的thousands的rpm. A 直驱 力矩电机 (e.g., 485SJM-1350BH, 1350/2400 N·m) gives high torque at low speed without 皮带 or 齿轮箱.
Series Coverage
丸作精工 MRDY series—MRDY-630, MRDY-500, MRDY-465与more—spans diameters与load ratings so you can select right foundation用于磨削, 车削, or five-轴 machining.
