EDM Plunger / Sinker

EDM Plunger / Sinker

Using a formed electrode usually made from graphite or copper, our EDM sinker fed vertically into the workpiece forms the reverse shape of the electrode and builds blind cavities.

 

Spark erosion vaporises and removes eroded metal before cooling, recreating the desired form in reverse. This process allows production of extremely complex and accurate internal profiles difficult to ordinarily machine, even with the most advanced CNC machine.
