EXTRUDE HONE Corporation to Exhibit New Electrolytic Machine at the WESTEC 2006 Exposition and Conference

Irwin, Pa. (March 10, 2006)-EXTRUDE HONE® Corporation announced today plans
to exhibit its new DeskLine(TM) machine, which features its Electrolytic Machining (ECM)
process, at the WESTEC 2006 Exposition and Conference in Los Angeles, Calif., from
March 27 - 30, 2006. Extrude Hone representatives will be available at booth #2412 to
discuss this latest addition to the company's innovative line of advanced finishing and
deburring technologies.

With the entry-level DeskLine machine, Extrude Hone offers customers all the innovation
and feature-rich capabilities inherent in its larger ECM machines. In addition, it's priced well under the annual costs of manual deburring operations, making the DeskLine
machine an affordable automated solution for many manufacturers.

Compared to manual deburring, which is proven to be tedious, unreliable, time-
consuming, and costly for large and small companies alike, Extrude Hone's DeskLine
machine boosts productivity substantially. In fact, it is capable of increasing productivity levels by up to 10 times over labor-intensive manual deburring methods. TypicalDeskLine cycle times range from 10 seconds to 30 seconds.

While a smaller-scale machine designed for lower production volumes, the DeskLine
is uncompromising in its ECM precision, reliability, and performance. A metal dissolution process, ECM uses a safe, low voltage DC electrical current applied to the tooling and workpiece while flowing an electrolyte between both surfaces to dissolve unwanted metal. The DeskLine machine works with part-specific tooling that precision deburrs equally well on both external and internal surfaces, and particularly difficult to access internal hole intersections.

The DeskLine machine capacity is rated at 3 kW (100 A/30 V), more than twice the
capacity of Extrude Hone's Miniburr product line, yet it is compact enough to fit within a 63-inch x 32-inch (1600mm x 800mm) footprint.

WESTEC attendees are encouraged to stop by booth #2412 to learn more about the
DeskLine machine and the entire ECM product line, as well as Extrude Hone's other
surface finishing and deburring technologies.
