What WGI does
WGI Inc. is a privately held, family-owned (Filios family, third generation) precision aerospace manufacturer and certified MRO provider headquartered in Southwick, Massachusetts, tracing its origins to a 1941 grinding shop founded by Louis Filios. The company operates two integrated divisions under one roof: an OEM precision parts business (WGI OEM) producing ultra-precision aerospace and medical components — spacers, seals, housings, gearboxes, shafts, knife-edge and honeycomb seals, bearing cages, and complex welded assemblies — and a certified MRO business (Westfield Gage Company Overhaul and Repair) that performs repair development and overhaul on commercial (CF34, CFM56, CF6, PW2000, PW4000, GP7000, V2500), industrial (FT4, PT8, GG4/8), and military (F100, F110, F117, F119, F135) engine components for airlines, engine centers, and asset managers.
Its core technology stack is built around sub-helium-light-band precision machining — tolerances to .0001 inches, flatness to .0000116 inches, and surface finishes to 1Ra — supported by 5-axis CNC machining up to a 38-inch envelope, CNC turning to 22-inch diameter, wire/sinker EDM, jig and surface grinding, flat lapping, honing, plasma/HVOF coatings, automated shot peen, balancing, heat treatment, and an in-house NDT lab. The 64,000 sq ft Southwick facility (expanded by 7,500 sq ft in March 2020) houses roughly 120 employees and a deep process-approval library including AS9100, ISO9001, NADCAP, FAA, EASA, CAAC, ITAR, and multiple OEM-specific approvals (PWA 46/49/50/52/53/257/36546/36550/97/106/99-3, Bell BPS 410/320).
WGI makes money through direct, quote-based B2B sales to enterprise aerospace customers, including Pratt & Whitney, GE Aviation, Honeywell, Rolls-Royce, Safran, MTU, Bell, Lockheed Martin, Raytheon, GKN, Stein Seal, Triumph Group, and the US Department of Defense, as well as to airlines and engine centers via its MRO division. Standard terms are net-30 with 1.5% monthly interest on overdue balances; quotes are custom per RFQ. The company exports to 40+ countries and supports aerospace qualifications including PPAP, Frozen Process, and Flight Safety.

Product offeringCore offering
WGI Inc. operates two divisions: an OEM division that designs and manufactures ultra-precision aerospace components (spacers, seals, gearboxes, shafts, bearing cages, complex welded assemblies) using CNC milling, turning, EDM, grinding, lapping, and honing to tolerances as tight as .0001 inches; and an MRO division (Westfield Gage Company Overhaul and Repair) that provides certified maintenance, repair, and overhaul of commercial, industrial, and military gas turbine engine components. Both divisions serve aerospace OEMs, airlines, engine centers, and defense customers globally.
Product overview
WGI Inc. operates two primary divisions: OEM (Original Equipment Manufacturing) and MRO (Maintenance, Repair, and Overhaul). The OEM division produces precision parts for aerospace and medical industries including spacers, scoops, levers, liners, gimbals, knife edge seals, bearing cages, shafts, gears, splines, and complex welded assemblies. The MRO division provides turbine engine component repair and overhaul services supporting commercial engines (CF34, CFM56, CF6, PW2000, PW4000, GP7000, V2500), industrial gas turbines (FT4, PT8, GG4/8), and military engines (F100, F110, F117, F119, F135). Both divisions share machining capabilities including CNC milling, turning, grinding, EDM, lapping, and honing.
