"The chemical milling process is an important step to adding greater manufacturing capabilities and value for our customers", said Dr. Peter Wright, President of Smiths Aerospace Components. "The process provides considerable weight reduction and superior structural performance in our engine components fabrication."

In addition to the new chem-mill process, the expansion will help accommodate the growing demand from Smiths' customers for precision fabricated turbine engine components for all major military and civil aircraft and engine manufacturers. The expansion is at the company's existing 333 Third Street location in Terre Haute.

Chemical milling involves a non-electrical process that removes metal from selected or entire areas through the use of a controlled chemical action. A chemical resistant maskant is applied to fabricated assemblies. Complex patterns are cut utilizing a multi-axis laser scribing unit. Immersion in state of the art, PLC-controlled tanks, removes material from the components. The process yields significant weight reduction and superior structural performance.

Smiths Aerospace, a part of Smiths Group, is a leading transatlantic aerospace systems and equipment company, with more than 10,000 employees and $2 billion revenues globally. The company holds key positions in the supply chains of all major military and civil aircraft and engine manufacturers and is a world-leader in digital, electrical power, mechanical systems, engine components and Systems Customer Services. www.geaviationsystems.com
