Inconel 713 Turbine Nozzle

Abstract

Technical Directions Inc. (TDI) in Ortonville, Michigan, was commissioned to produce a small jet engine for the Loitering Attack Missile (LAM). This system is currently being reviewed by the Army at Redstone Arsenal for use in the NLOS-LS (Non-Line of Site Launch System) system. TDI in turn enlisted Extreme Precision Screw Products of Flint, Michigan, to machine key engine components. The high-temperature materials used in jet engines present machining challenges that include limited metal removal rates and frequent tool failure. For a turbine nozzle made of Inconel 713 nickel-base alloy, Extreme Precision sought ways to increase productivity in drilling and turning operations and also overcome problems encountered when using taps to thread small-diameter holes.
