Fully automatic Vertical 1-plane balancing machine

Fully automatic balancing machine for pump impellers has been released on 1994. Once workpiece is mounted on the machine, measurement and correction are performed at same arrangement. Correction of unbalance is performed by lathe-unit; therefore surface of the workpiece is smooth after unbalance correction.

  • Balancing plane : 1 plane
  • Workpiece Mass : 30kg max.
  • Rotor dia.: ø600mm max.
  • Chucking adapter : Manual fixing
  • Balancing Speed : 800min-1
  • Min. Achievable Unbalance :1.0 μm

Pump impeller, Flywheels, etc.


  • Fully automatic
  • Fully automatic operation from measurement to correction without set‐up change.
    High-accuracy balancing because no cumulative error of reattaching.

  • Unbalance correction by lathe-unit
  • High accuracy unbalance correction
    No step after cutting, suitable for fluid machinery parts.

  • Built-in spindle motor
  • Steady measurement because there is no transmission component which is cause of disturbing vibration.

  • Small foot print
