            •  An integrated cooling loop (closed circuit dielectric or water glycol mixture) maintains optimal operating
              temperatures, ensuring consistent pulse shapes even under heavy cycling.

            •  Its placement is also optimized, located in relatively the same position on each machine, making cable lengths
              similar, thus reducing performance differences regardless of the machine model chosen.

          2. Active Current Shaping
            •  Proprietary switching mode power conversion enables fi ne control over rising and falling edges of spark current.

            •  This “waveform sculpting” minimizes unwanted secondary discharges, sharply reducing electrode wear and
              preserving corner fi delity in micro features.

          3. No Taper, No Problem

            •  Exogen’s advanced spark circuitry enables completion
              of all types of jobs, not just “Rib” making, but also
              small undersize, no taper, fi ne electrodes.
            •  Utilizing taper on electrodes for increased metal
              removal rates (common on EDM Sinkers) is
              unnecessary, drastically reducing cycle times on
              those “Hard to Burn” jobs.

          4. Database Driven Technology Selection

            •  A comprehensive, extensible database maps
              electrode material, gap conditions, and target fi nish
              to optimized pulse paradigms (e.g., high duty
              roughing, low energy fi nishing, and polishing erosion).
          5. Retrofi t Friendly
            •  Exogen’s electrical and mechanical interfaces mimic
              legacy Exeron generators, allowing seamless
              replacement and integration. Existing tooling, cabling
                                                                    0° End Taper Cutting Performance Benchmark
              harnesses, and dielectric circuits remain unchanged.

             PERFORMANCE HIGHLIGHTS
          •  Surface Quality
            Users report up to 30% improvement
            in Ra values during fi nishing passes
            compared to traditional generators,
            without increasing cycle times.
          •  On Average, Surface Finishes are
            Uniform Within +/-5%
          •  Electrode Longevity

            Active current shaping cuts tungsten
            and copper electrode wear by
            20–25%, translating into lower tooling
            costs and fewer changeovers.
          •  Turnkey Polishing Module
            Once a specialty process, polishing
            EDM becomes a standard step:
            Exogen executes sub-10 µm RMS
            fi nishes with data-backed
                                                             Exogen Provides Surface Finish Range From
           consistency.
