Built on decades of machining experience.
M.A.R.'s Engineering Company Inc. was founded in 1964 by Manuel and Reine Ambrosio and has remained family-run ever since. Over the decades, the company expanded from precision screw machining into a broader in-house manufacturing operation with CNC turning, multi-spindle production, centerless grinding, Wire EDM, finishing, and assembly support. That growth allows us to serve customers seeking precision turned components in Savannah with fewer outside vendors, tighter process control, and more dependable turnaround. We understand that manufacturers supporting port activity, transportation, electronics, and industrial operations around coastal Georgia need repeatable quality and responsive production planning. Our vision is to remain a trusted machining partner by combining proven craftsmanship with continued investment in modern equipment and process capability.
A precision turned component is a machined part made on turning equipment such as CNC lathes, Swiss machines, or screw machines, where the material rotates while tools shape it to exact dimensions. These parts often include shafts, pins, bushings, fittings, threaded parts, and miniature components that require tight tolerances, smooth finishes, and repeatable geometry across production runs.
