A dependable shop partner
From concept to finished part.
D & A Machining is a full-service machine shop built around long-term customer relationships. We combine large- and mid-size CNC capacity with hands-on manual support equipment, careful inspection, and practical mechanical design.
The goal is simple: quality parts, delivered on time, at a competitive price—even when a project needs to move quickly.
Good work starts with understanding the job. We worked with Wannawow to bring that same approach to our website.
