Sinker Electrical Discharge Machining Service, like Wire EDM machine services, uses spark erosion to machine blind cavities.

The Sinker EDM machine process employs machined electrodes that produce sparks along the surface of the electrode to sink or plunge the cavity. The Sinker EDM machine process is ideal for a number of applications:

• Blind Cavities
• Intricate Details
• Sharp Corners
• Fine Finishes (Surface Finishes to 10 Micro-Inch)
• Thin Walls and Cross Sections
• Machining Threads into Hardened Parts
• Blind Keyways
• Internal Splines, Squares, or Hexes
• Any conductive material can be Sinker EDM machined, including PCD, CBN, Aluminum, Brass, Carbide, Copper, and Titanium.

Big Sky EDM has complete in-house electrode manufacturing capabilities. Electrodes for Sinker EDM machining are generally made from Copper, Graphite, or Tungsten depending upon work piece material and electrode wear requirements.

Our Charmilles Roboform Sinker EDM machines are outfitted with a C-Axis for orbital and helical machining, as well as tool changers to increase unattended machine time and minimize cost to our customers.
