Sinker EDM Technology

April 9, 2012

Makino has released the latest version of its SuperSpark™ sinker EDM technology, SuperSpark IV, which, according to the manufacturer, reduces roughing times in deep-rib applications by up to 30 percent.

It does so by using a combination of shortened jump cycles and spark-gap adaptive power control to improve process efficiency and productivity. In standard sinker EDM jump cycles, more than 60 percent of total process time is spent out of the cut. This new technology more than doubles the actual cutting time because its shortened jump height requires less time for electrodes to return to the workpiece.

In addition, the spark-gap adaptive power control enables electrodes to discharge sparks during the jump cycle for continuous cutting throughout the EDM process. As the electrode depth increases, the power and spark gap decrease to prevent overburn.
