Our Scope
Lynch Bros. provides high-accuracy CNC milling, turning, and multi-axis machining (3-, 4-, and 5-axis), supporting both prototype development and production manufacturing. Our vertically integrated capabilities include precision tube bending, advanced sheet metal fabrication, and certified special processes including aluminum heat treatment, fusion welding, resistance welding, and brazing.
Our manufacturing systems are designed to meet the stringent demands of aerospace, defense, industrial, and high-performance applications, delivering tight tolerances, process consistency, and repeatable quality at scale.
Sheet Metal Fabrication
Rapid Prototyping
We provide fast turn prototype machining for engineering teams, R&D; departments, and pre production development cycles. Our prototype support ensures that parts are delivered quickly while maintaining tight tolerances, giving customers confidence before entering full production stages.


Multi Axis Machining Solutions
For complex geometries and components requiring multiple machining operations, our multi axis machining solutions reduce setup time, improve efficiency, and ensure precision on intricate aerospace and defense hardware. This capability allows us to manufacture parts with unique angles, contours, and critical dimensional requirements.

Production Manufacturing
For customers requiring consistent, repeatable machining across multiple production runs, Lynch Bros. MFG. CO. delivers stable process control and rigorous quality checks. Our production machining workflow supports aerospace, industrial, and defense programs where accuracy and reliability must be maintained over time.
