EDM Machining and Current Drilling
Precision offers four Charmilles wire
EDM machines and one EDM current
drilling machine. The largest of the
EDMs is a Charmilles Cut 300 which
includes a water tank to fully sub-
merge the fixture, tool head and part to
be produced. By controlling the entire
environment, tolerances drop dramati-
cally. With the wire EDM process
there is no tool pressure and no tool
wear which are both common issues
with traditional CNC machining re-
sulting in very low tolerances.
The wire EDM process can use wire
diameters from .001” up to .012” to
handle a wide range of applications.
EDM also produces very sharp corners
and edges for demanding application.
A major advantage of wire EDM is the
superior finish that is produced as it Machine Capacities
