Key Takeaways:
The MRDY-630 is Marusaku's representative φ630 mm hydrostatic direct-drive rotary table: 1000 kg load at 3.5–4 MPa, ±0.001 mm accuracy, 485SJM-1350BH torque motor, and Heidenhain RCN2380 feedback.
Overview
The MRDY-630 is the representative model of Marusaku's hydrostatic direct-drive rotary table series. Its φ630 mm worktable floats on a 3.5–4 MPa oil film, keeping the friction pair fully non-contact for life.
