Also included at the Great Lakes facility is a computerized Empire Abrasives shot peening system, where steel shot is used to meet the design requirements of the customer under accurately controlled settings. Hardened gear teeth and specified areas of the machine part are peened to increase fatigue strength and life of the gear. An Almen strip test is used to verify the intensity for each job order. Our shot peening process is certified to the Mil standard 13165-C.
