The unique rotary / tilting table from Ocean Technologies is technical breakthrough for multi-axis EDM Drilling performance, with 360 rotation and wide tilting range up to 120, both axes are driven by DD motor, providing a versatile and accurate A, B axes.


The spindle position can be shifted towards the operator’s direction (Y+), this design allowing the drilling work goes into a vertical cavity, such as aluminum alloy car wheel. Such a unique design only available in Ocean Technologies machines.


Electrode Trimming
Electrode tip is cut off and trimmed after drilling, eliminating irregular wearing or sharp shaped tip; maintaining higher accuracy and repeatability for next hole.


Auto Tool Changer (ATC) and Auto Guide Changer (AGC) are standard features of OCT-90120CA. 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 elec trodes whie machining electrode is run out.
  • Once the machining depth is reached, the electrode automatically returns to a fixed height above the workpiece.

Extra Large Coolant Tank
Extra large coolant tank, 250 liters capacity with two paper filter cartridges, plus high performance water chiller, the machine runs under correct and clean conditions for accurate and stable sparking.
