EDM Hole Drilling

If your parts or components require extremely small-diameter holes drilled contact Kaplun Mfg.  We offer EDM hole drilling services to meet the needs of any industry or application.

What is EDM Hole Drilling?

EDM (electrical discharge machining) hole drilling works on the same technical principles as wire EDM processing. However, instead of wire, EDM hole drilling uses an electrically-charged metallic electrode tool that works much like a traditional drill bit for hole machining. The material being worked serves as the second electrode, and electrical discharge between the workpiece and the tool creates sparks that rapidly cut away material. Both the electrode tool and the workpiece are submerged in deionized water, which flushes away cutting debris and acts as a dielectric safety barrier.

There is no physical contact between the tool and the workpiece; therefore, no cutting forces are involved. This enables extremely high dimensional accuracy, and results in drilled holes with fine finishes that require no additional work to remove burrs or smooth the surface.

Wire EDM

Wire EDM, or electrical discharge machining, is a high-precision method for cutting nearly any electrically conductive material. A thin, electrically-charged molybdenum EDM wire held between upper and lower mechanical guides forms one electrode, while the material being cut forms a second electrode. Electrical discharge between the wire and the workpiece creates sparks that rapidly cut away material and flushing system flushes away cutting debris.

As the charged wire never makes physical contact with the workpiece in EDM machining, there are no cutting forces involved, making it possible to manufacture extremely small and/or delicate parts. Parts that require levels of accuracy and intricacy that traditional machining cannot achieve can easily be produced via wire EDM.

MOLYBDENUM (Moly) wire has a much higher melting point and higher tensile strength than any other material used for electrical discharge machining this gives us ability to machine veriety of softest and hardest materials from .010 to 10.00 in thickness and keep tolerances as close as 1 micron or .0002 .We love machining carbide and other tungsten alloys as well as any other heat treated tool steels.
