Marusaku Seiko's hydrostatic direct-drive rotary table uses liquid hydrostatic bearing support: the worktable floats on a 3.5–4 MPa oil film with no mechanical contact, giving extremely low friction, high rotary accuracy, vibration resistance, and thermal stability.
| Item | Parameter (φ630) |
|---|---|
| Table diameter | φ630 mm |
| Load capacity | 1000 kg @ 3.5–4 MPa |
| Rotary accuracy | ≤ ±0.001 mm |
| Direct-drive torque motor | 485SJM-1350BH, 1350 / 2400 N·m |
| Position feedback | Heidenhain RCN2380 rotary encoder (closed loop) |
| Sealing | Air-curtain seal |
| Series | MRDY-630 / 500 / 465 |
The combination of non-contact hydrostatic support and direct-drive torque motor eliminates gear backlash and belt error, making the table ideal for high-accuracy dividing, contouring, and multi-face machining.
