Sinker EDM Machining

Sinker EDM, Conventional EDM, Ram EDM, Plunge EDM and Die-Sinker are all one in the same. They can all be used to add another dimension in CNC Machining. This process uses custom machined electrodes that produce sparks alongside the surface of the electrode to machine, sink or plunge the cavity. The Sinker EDM process is very ideal for a wide variety of applications, such as:

• Blind cavities
• Intricate details
• Sharp corners
• Fine finishes (surface finishes to 10 micro-inch)
• Thin walls
• Machining threads into hardened parts
• Blind keyways
• Internal splines, squares, or hexes
• Tolerances can be held to .0001"

Any conductive material can be machined using Conventional or Sinker EDM such as, but not limited to Aluminum, Brass, Carbide, Copper, Hastalloy, Inconel, Kovar, Stainless Steel, Tool Steels, and Titanium.

Electrodes for Sinker EDM machining are generally made from Copper, Graphite, or Tungsten depending upon work piece material and electrode wear requirements.
