River CNC EDM Hole Drilling Machines
High-Performance Multi-Axis CNC EDM Drilling for Complex, Safety-Critical Components
The River CNC Series from Ocean Technologies delivers advanced EDM hole drilling capability for industries where precision and repeatability directly impact human safety. Aerospace manufacturers rely on these systems for cooling holes in turbine blades and vanes, fuel injector nozzles, and multi-angle airfoil features that must meet strict aviation standards. Medical and life-science companies depend on the River CNC platform for micro-holes in biopsy needles, catheter tips, stents, pacemakers, and orthopedic implants. In the automotive sector, the series produces precision holes for fuel injection systems, ABS and brake components, and hydraulic and pneumatic assemblies.
Using controlled high-frequency electrical discharges, the River CNC machines drill accurate holes from 0.1–3.0 mm across a wide range of conductive materials including stainless steel, hardened steel, carbide, titanium, Inconel, superalloys, ceramics, graphite, and more. High-precision servo control, rigid casting construction, and linear guideways ensure stable micro-electrode performance — even when drilling on slopes, curves, or contoured surfaces. These machines can also remove broken taps or drills without damaging the original hole or threads.
