What Stellar Precision Components Ltd does

Stellar Precision Components Ltd is a privately held, women-owned precision machining job shop founded in 1978 and headquartered in Jeannette, Pennsylvania. The company manufactures tight-tolerance, mission-critical components and assemblies for the U.S. aerospace and defense industries, with additional work in commercial aerospace, Navy nuclear manufacturing, and industrial segments. Its customers include U.S. Armed Forces programs such as rocket launch and missile systems, and it operates as a Tier/lower-tier supplier to primes under AS9100 Rev D, ISO 9001:2015, ITAR, and GIDEP frameworks.

The company's core offerings are organized around three integrated capabilities: multi-axis CNC machining (3-, 4-, and 5-axis milling), CNC turning (up to 30 inch diameter and 120 inch length with tolerances routinely held at +/- .001), and Wire EDM using Mitsubishi equipment. These machining services are wrapped by an in-house Non-Destructive Examination (NDE) laboratory offering Magnetic Particle Testing, Liquid Penetrant Testing, and Hydro Testing, and by a multi-vendor Coordinate Measuring Machine (CMM) inspection fleet that supports statistical process control and full data packages with every shipment. The result is a vertically integrated, turnkey operation that reduces reliance on external vendors and shortens lead times for aerospace programs.

Stellar generates revenue on a quote-based, project-by-project basis through direct B2B field sales to enterprise and government aerospace and defense buyers. It operates as a private, certified women-owned small business (WOSB, WBENC) with no disclosed institutional investors, no parent company, and no public financials, serving as a domestic U.S. precision machining supplier with a workforce of 65+ veteran Journeyman Machinists and Technicians.
