Our conventional EDM
department is equipped with seven sinker EDM machines and an Aztec
hole shooter. We have Charmilles, Eltee and Elox machines. This
gives us a wide range of capacity and capabilities. All electrodes
are filed and stored in order to reduce costs on repeat jobs. The
EDM machines are equipped with the 3R system to insure accuracy
and repeatability. The other departments that manufacture and dress
the electrodes also use the 3R system.
Our operators have the expertise to burn carbide as well as the
various tool steels used by our customers. Whether a punch face
is for a miniature electrical contact or a large surface area with
multiple features our operators are trained to achieve the best
possible surface finish. The less the recast layer is, the better
the detail on the finished face. This helps avoid distorting the
face features during the polishing process. We apply the same concepts
when burning choke/step dies.
The Wire EDM
department is equipped with three Mitsubishi wire machines and one
Makino wire machine capable of using .004, .006, .008, .010, and
.012 diameter wire for a variety of applications. With taper and
auto-threading capabilities the wires can and do run around the
clock to meet tight delivery schedules. Integrating wire EDM into
production in the 1970s gives CTI employees 30 years of experience
with the process.
