EDM CNC & Manual Hole Drilling Machines

High-Precision Small-Hole EDM Drilling for Demanding Manufacturing Environments

Absolute Machine Tools proudly represents River EDM CNC and manual hole-drilling machines from Ocean Technologies. Established in 2000, Ocean Technologies has grown into a global leader in high-accuracy small-hole EDM solutions โ€” including wire start holes, turning-and-burning operations, and advanced multi-axis configurations for 3- through 6-axis drilling. The River Series is engineered for precision micro-drilling in aerospace, medical, tooling, and other industries that rely on stable, repeatable, high-tolerance holemaking.

Built on heavy Meehanite cast structures with precision guideways and intelligent digital control, River EDM systems deliver the rigidity, burn stability, and dynamic accuracy required for deep, angled, or shaped-hole drilling. High-pressure flushing, advanced HP1+ discharge technology, and optional automation packages ensure reliable performance while streamlining downstream wire EDM cutting and improving overall shop throughput.

Benefits for Metal Cutting Manufacturers

  • Exceptional Small-Hole Precision: Maintains tight tolerances and clean hole geometry โ€” even in deep, angled, or hardened-material drilling.
  • Higher Throughput: HP1+ high-speed discharge circuitry increases drilling speed by up to 40% while reducing energy use by 30%.
  • Unattended Drilling Capability: Optional automatic electrode and guide changers, rotary tables, tilting heads, and robotic workpiece changers support lights-out multi-hole production.
  • Multi-Material Performance: Efficiently drills titanium, Inconel, tool steel, and copper alloys with high-pressure through-spindle flushing for debris-free burn stability.
  • Optimized for Wire EDM: Produces precise start holes that shorten setup time, improve accuracy, and increase productivity in downstream wire-cutting operations.
  • Rigid, Thermally Stable Construction: Heavy-ribbed Meehanite castings and linear guideways ensure vibration-free operation and long-term repeatability.
