Makino 2008 EDNC207S

Sinker EDMs are ideal for hardened conductive materials and complex part details that are difficult to machine by other methods. While the electrical discharge machining process is usually slower than conventional milling, it excels at producing small deep features that are beyond the capability to mill to repeatable high accuracy.

Makino Sinker EDM machines speed up the spark erosion process by improving flushing and debris removal through an increase in the Z-Axis cycle jump rate four times faster and acceleration rate 30 times faster than previous technology.  The enhancements to adaptive jump flushing and the all new higher power fully digital ES200A generator yield faster Sinker EDM machining speeds with significantly lower electrode wear.

The result: fewer electrodes required, faster cycle time with lower costs, and more uniform surface finishes that can eliminate the need for manual hand polishing.

The seven EDNC machine models bring similar capabilities as the EDAF-Series but with larger platforms to accommodate a wider range of workpiece sizes. Machines can be equipped with the HS-Rib high speed jump Z-Axis to be as productive and accurate as smaller machines.
