Extrude Hone Corporation to Exhibit New Electrolytic Machine at the IMTS 2006 Exposition in Chicago

Irwin, Pa. (June 1, 2006)-EXTRUDE HONE® Corporation announced today plans
to exhibit its new DeskLine machine, which features its Electrolytic Machining (ECM)
process, at IMTS 2006 in Chicago, Ill, from Sept. 6 - 13, 2006. Extrude Hone representatives will be available at booth 7100, North Hall B 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 process machines. In addition, its moderate pricing makes the DeskLine machine an affordable automated solution for all manufacturers that perform deburring operations.

Compared to manual deburring, which has proven to be tedious, unreliable, and
time-consuming for large and small companies alike, Extrude Hone's DeskLine
machine boosts productivity substantially. In fact, it increases productivity levels by
up to 10 times over manual deburring. Typical DeskLine cycle times range from
10 to 30 seconds.

While a smaller-scale machine designed for lower volume production, the DeskLine is
uncompromising in its precision, reliability, and performance. A metal dissolution process,ECM uses an electrical current applied to the tooling and workpiece while flowing an electrolyte between both surfaces to dissolve unwanted metal.

The DeskLine machine improves surface quality of parts that are cast, machined, forged
or processed using Electrical Discharge Machining (EDM). The ECM process removes
material ranging from 0.0005 inch to 0.01 inch and realizes a 5 - 10 surface roughness
improvement factor in most applications. It works equally well on both external and
internal surfaces, particularly difficult to access internal bores and intersecting holes.

The DeskLine machine is available in a standard version rate at 3 kW (100 A/30 V or 50
A/60 V). IMTS 2006 attendees are encouraged to stop by booth 7100 in the North Hall B to view a demonstration of the DeskLine machine and the entire ECM product line, as well as Extrude Hone's other finishing and deburring technologies.
