What is Small Hole EDM?

Small Hole EDM

Small hole edm is a specialized component of electrical discharge machining. A small hollow electrode spins about a spindle much like a drill and drill bit (EDM drill). The electrode is electrically charged by a servo-controlled generator producing the spark. Water based dielectric flushes through and around the electrode providing a controlled environment for the spark to jump to the work piece. The electric spark erodes the surface of the work piece creating very small pockets. Eventually millions and millions of these microscopic pockets create the small hole. The size of the hole is controlled by the diameter of the electrode. The location and depth of the holes are driven by CNC ISO codes, reducing and eliminating operator error. Machines shown have automatic electrode changers for unattended machining.

Applications

EDM Small Hole Drilling

Small hole edm is in many ways similar to a drilling operation but it offers the advantages of edm. Very low machining and work piece hardness are not barriers to performance. A short list of common applications follows.

HIGH SPEED SMALL HOLE SIZE CAPABILITIES

Small Hole Electrical Discharge Machining

*Up to 14" part height possible, depending on part configuration.

Max. XY travel: X-22.25" & Y-14.25", other sizes may be available with lead time and/or large quantity orders.
