Fast Hole Drilling

Fast Hole Drilling

We have the capability for edm hole drilling from 0.1mm to 3mm diameter holes in any conductive material. As well as generating start holes for Wire Erosion, these machines can remove broken taps and fasteners, avoiding costly scrapping.

Small hole EDM is used to drill rows of holes into the leading and trailing edges of turbine blades used in jet engines. Gas flow through these small holes allows the engines to use higher temperatures than otherwise possible. The high-temperature, very hard, single crystal alloys employed in these blades makes conventional machining of these holes with high aspect ratio extremely difficult, if not impossible.

Small hole EDM is also used to create microscopic orifices for fuel system components, spinnerets for synthetic fibers such as rayon, and other applications.

Small-hole drilling EDMs are able to drill through 100 mm of soft or through hardened steel in less than 10 seconds, averaging 50% to 80% wear rate. Holes of 0.3 mm to 3 mm can be achieved in this drilling operation.
