Makino's EDAF-Series Sinker EDM with ArcFree Technology Spark Gap Monitoring and DC Arc Prevention

The new EDAF series contains Makino's most sophisticated sinker EDM technologies to date, including the new ArcFree technology. This new technology helps prevent destructive DC arcs that typically lead to time-consuming clean-up procedures or scrapped parts. With ArcFree Technology, manufacturers can burn any application, fully unattended, worry-free. Even applications with unfavorable electrode/work piece geometry that are accidentally started with unusually high current density can be relied upon for flawless results.

In this video you will see a burn held at four times the recommended current density. With standard arc detection/prevention enabled, the burn is continually adjusted by the adaptive control, but is unstable and has the potential to produce a DC arc. Once all arc detection/prevention technologies are disabled highly destructive DC arc activity develops. With ArcFree technology enabled, the burn becomes stable again and machining continues through the arc-damaged areas. Immediately after ArcFree technology is turned off and standard arc detection/prevention in enabled, the arcing returns, as would be expected of any machine once an arc develops.
