Precision Ground Gears - Delta Gear - Livonia, MI
Jet engines operate in the range of 25,000 to 30,000 rpm, and doing so requires precision parts finished with near mirror surfaces. Delta Gear makes parts like these all day long in a clean room facility with glass walls. Offices and meeting rooms all had quartz tops, so this background was an easy choice. This photo was selected as the cover for the magazine that ran the case history written by RYB Communications.
