Midwest Aerospace & Defense Precision Machining

Full Editorial Writeup

This is a Macomb County, Michigan precision machining and custom tooling operation serving aerospace, military, defense, and naval end markets, plus select advanced industrial clients. The shop runs across multiple climate-controlled facilities with a deep inventory of specialized machinery and holds quality certifications required to compete in regulated industries. Capabilities span specialty machining, custom tool fabrication, mold base construction, waterjet cutting, gun drilling, grinding, and assembly, with work that is predominantly custom and project-driven rather than tied to a narrow band of repeating contracts.

The business does $5.735M in revenue with $1.115M in SDE, a healthy 19.4 percent owner earnings margin for a shop of this size. It served over 80 customers in a recent year with no single account dominating revenue, which is exactly the kind of diversification that de-risks a defense supply chain platform. Management is already in place, including a general manager, project managers, engineering staff, and 36 total employees, while the retiring owners operate remotely in a limited oversight role.

What makes this notable is the deliberate pivot the company made away from lower-margin legacy work toward higher-value aerospace and defense machining, which lifted both top line and profitability. The team is long-tenured and technically capable, the certifications create switching friction, and the defense/aerospace tailwind gives a buyer a scalable platform rather than a one-person job shop.
