Founded in 1978 as a two-person shop, Giuliante Machine Tool Inc. manufactures precision aerospace gears, splines, and related machined components for military and commercial aircraft. The company has grown from a 3,500-square-foot Port Chester operation into a 27,000-square-foot facility, while retaining a distinctive in-house approach: it finish-machines its gear blanks under one roof rather than subcontracting that work. GMT’s quality system is certified to AS9100 Rev. D and ISO 9001:2015, with inspection performed in a climate-controlled lab using NIST-traceable gauges.
