What Ace Precision Machining Corp. does

Ace Precision Machining Corp. (DBA Ace Precision) is a privately held, family-owned precision CNC machining manufacturer founded in 1982 and headquartered in Oconomowoc, Wisconsin. The company operates two Wisconsin facilities totaling approximately 100,000 square feet — a 90,000 sq ft corporate and OEM manufacturing center in Oconomowoc (constructed 2003, expanded 2015) and an FAA-certified repair station in Menomonee Falls — and is classified as a small business entity. Across roughly 251-500 employees it serves the gas turbine value chain in aerospace, power generation, defense and space, and aftermarket/MRO end-markets.

The company's core offering is a vertically integrated suite of nine in-house capabilities — multi-axis CNC machining (3-, 4-, and 5-axis up to a 36-inch envelope), nonconventional machining (CNC fiber, CO2, and YAG lasers with up to 8-axis simultaneous motion, plus wire EDM), engineered coatings (robotic thermal spray including ceramic thermal barrier, abradable seals, and metal restoration), thermal processing (vacuum heat treat, brazing, aluminum heat treat), metal forming (hydroforming at 10,000 PSI up to 25-inch blanks, plus expansion, roll, and press forming), metal joining (robotic GTAW, laser, resistance, orbital tube welding), electron beam welding (two units at up to 250 mA), process engineering, and a comprehensive quality system with NDT (fluorescent penetrant inspection, computed radiography) and CMM inspection. Process accreditations include NADCAP across welding, nonconventional machining, heat treat, NDT, and coatings; AS9100D/ISO 9001:2015; FAA Air Agency #QAPR054K; EASA #EASA.145.4015; and UK CAA Part 145 #UK.145.50617. Customer source approvals from Honeywell, Siemens Energy, Rolls-Royce, Northrop Grumman, and Blue Origin are explicitly disclosed.

Ace Precision generates revenue through B2B precision machining and remanufacturing services for OEM customers and through FAA-certified aftermarket inspection, repair, and overhaul of gas turbine engine components. Pricing is custom quote-based (no public pricing). Its go-to-market is enterprise field sales targeting OEM program buyers in aerospace (Honeywell, Rolls-Royce, Pratt & Whitney), power generation (Siemens Energy, Capstone, Woodward), and defense and space (Northrop Grumman, Blue Origin), complemented by an FAA/EASA/UK CAA-certified repair station that serves StandardAero-style aftermarket customers with rotation-pool components for fast-turn hot-section repair. Marketing is anchored by the company's website with a "Request a Quote" intake, certification display as a credibility lever, and organic search, with no disclosed channel diversification such as distribution partners or digital self-serve.

Core offering

Ace Precision is a vertically integrated precision machining manufacturer producing complex gas turbine engine components (combustion liners, nozzles, turbine plenums, shroud assemblies, bearing supports, missile cones) from nickel, cobalt, stainless, and aluminum alloys for aerospace, power generation, defense, and space OEMs. Capabilities span CNC multi-axis machining, laser and EDM nonconventional machining, thermal spray coatings, vacuum heat treatment and brazing, hydroforming and metal forming, electron beam and orbital tube welding, and FAA-certified aftermarket repair and overhaul. Process control is maintained in-house from raw material through finished component and testing.

Product overview

Ace Precision Machining Corp. is a vertically integrated precision manufacturing company offering a comprehensive suite of metalworking capabilities under one roof. The company's core product portfolio consists of 9 interconnected manufacturing capabilities: CNC Machining (5-axis), Nonconventional Machining (laser and EDM), Engineered Coatings (thermal spray), Thermal Processing (vacuum heat treat and brazing), Metal Forming (hydroforming, expansion, roll), Metal Joining (multiple welding processes including robotic GTAW, laser, resistance, orbital), E-Beam Welding, Process Engineering, and Quality System/Non-destructive Testing. These capabilities are deployed across two Wisconsin facilities — an Oconomowoc manufacturing center serving OEM production and a Menomonee Falls FAA-certified repair station. The company specializes in manufacturing complex gas turbine engine components (combustion liners, nozzles, turbine plenums, labyrinth seals, honeycomb seals) and complex assemblies for aerospace, power generation, defense, and space applications. Vertical integration ensures process control from raw material through finished component.
