River 700

Submerged Type Water Tank Superior Workpiece Surface

For customers who require fine finish surface, the River 700 is the first choice. The submerged water tank allows quality and efficient sparking performance even on irregular shaped work pieces. In addition, the travel column structure features constant load on all 3 linear axes, the integrated design is perfectly suitable for aerospace component's mass production, especially the turbine blades in the turbo engine.

Oversized lower arm fully supports the rotary table unit, with the IP68 isolation class plus an external position encoder, the swiveling accuracy may reach up to +/- 25 sec.

Auto Tool Changer (ATC) and Auto Guide Changer (AGC) are standard features of River 700. The reliability of ATC and AGC ensures long term operation accuracy and high productivity.

  • ATC Capacity: 16 or 32 tools
  • AGC Capacity: 10 blocks
  • Auto compensation of replacement new electrodes while machining electrode is run out.
  • Once the machining depth is reached, the electrode automatically returns to a fixed height above the workpiece.
