A Tier-1 defense contractor rejected parts from their primary vendor for a high-end precision pin used to affix fins onto missiles. The rejection of the pins caused a delay in shipment of missiles to The Persian Gulf, and left them with no source for the pins after the primary vendor lost approved status. The Tier-1 contractor needed to ship missiles within 2 weeks otherwise late delivery penalties would be assessed. Material: 440C HT 55Rc min
Diameter .19000 +/- .00003” (30 millionths)
Flats and specific nose configuration
Parts needed to be manufactured "complete" in a 1-2 week time frame!
Resolution: Parts were manufactured complete in 10 days from purchasing material, blanking, HT and all grinding operations. All features were ground, including nose angle and nose radius. The diameter sizes needed to be recorded and the parts bagged tagged to match the parts up for press fitting into existing holes in missile wings. The customer was able to keep to their quoted delivery schedule and avoid penalty. Grinding discipline(s) that contributed to resolution: Ultra-Precision Centerless, CNC Centerless
