Our hole drilling machine are CNC controlled which allows us to burn hole patterns with close locational tolerances. It is also very large allowing for work pieces of up to 1000 lbs. and 20 inches thick.
EDM hole drilling was originally used for putting in starter holes for the Wire EDM machines. We still use it for this purpose everyday. We can put starter holes in as small as .015 diameter and as deep as 20 inches. It doesn’t matter if the material is hard or soft, aluminum or carbide. We also use this machine to drill small holes in a variety of types of parts.
We can put wire safety holes in parts where the hole goes through a slanted or curved surface and conventional drilling would be very difficult. We can drill a .015 hole in a nozzle where conventional drilling would not be possible. In certain applications we can hold diameter tolerances of +/- .001
