Conventional EDM
Conventional & Small Hole EDM uses spark erosion to machine intricate details and is ideal for numerous applications.
Conventional EDM (Sinker EDM machining), like Wire EDM, uses spark erosion to machine blind cavities.
This process employs machined electrodes that produce sparks along the surface of the electrode to sink or plunge the cavity. The Conventional EDM 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
Tolerances to +/- .0001”
Any conductive material can be Conventional EDM machined, including aluminum, brass, carbide, copper, hastalloy, inconel, steel, stellite, and titanium. RPG Industries has in-house electrode manufacturing capabilities.
Electrodes for Conventional EDM machining are generally made from copper, graphite, or tungsten depending upon work piece material and electrode wear requirements.

Small Hole EDM
Small Hole EDM
Small Hole EDM drilling uses the same spark erosion principle as Conventional EDM. Small Hole EDM is ideal for adding ejector holes in hardened punches, coolant holes in cutting tools, vent holes in molds, and start holes for Wire EDM.
RPG Industries offers Small Hole EDM Machining capabilities from:
.006" diameter to .140" diameter
10" drilling depth
Up to 850 pound workpiece weight
