CNC Turning
Produce aerospace shafts, bushings, fittings, and threaded parts with consistent dimensional accuracy, live tooling capability, and support for both prototype and production quantities.
M.A.R.'s Engineering delivers aerospace CNC turning solutions for precision components, threaded parts, fittings, shafts, and miniature features with tight tolerances, full traceability, and integrated finishing. Backed by decades of machining experience and AS9100-aligned quality practices, we support prototype through production runs for demanding aerospace applications.

Precision turning solutions for aerospace parts, from prototypes to high-volume production with integrated secondary operations.
Produce aerospace shafts, bushings, fittings, and threaded parts with consistent dimensional accuracy, live tooling capability, and support for both prototype and production quantities.
Manufacture small, complex aerospace components with exceptional stability and tolerances as tight as ±0.0001 inches using Swiss-type CNC turning processes.
Handle high-volume aerospace turned parts efficiently with simultaneous operations that reduce cycle times while maintaining repeatable quality across large runs.
Create micro-scale aerospace parts, pins, spacers, and intricate turned features where conventional machining cannot achieve the required geometry or tolerance.
Machine aerospace fittings and connectors with threads, grooves, ports, and sealing features completed in fewer setups for better feature alignment.
Produce precision aerospace shafts and pins with close diameter control, fine finishes, and optional grinding or plating for ready-to-install performance.
Aerospace programs demand repeatability, traceability, and exacting dimensional control. M.A.R.'s Engineering combines CNC turning, Swiss machining, screw machining, grinding, and in-house finishing to deliver complex turned components from prototype through production. With nearly 60 years in precision manufacturing and ISO-compliant systems, we help buyers reduce vendor handoffs, shorten lead times, and maintain confidence in every machined part.

Built on decades of machining knowledge.
M.A.R.'s Engineering Company Inc. has been family-run since 1964, when Manuel and Reine Ambrosio founded the business to specialize in precision screw machining of complex parts. Over the decades, the company expanded its capabilities through new equipment, a second operations department, multi-spindle capacity, and the addition of CNC and Wire EDM technology. Today, M.A.R.'s Engineering continues to serve demanding industries such as aerospace with an integrated manufacturing approach that brings machining, finishing, and assembly together under one roof. That long-term investment in equipment, process control, and customer relationships allows the company to support both prototype development and repeat production with the consistency, responsiveness, and traceability modern manufacturing programs require.
CNC turning machine costs vary widely based on machine size, spindle configuration, live tooling, automation, and precision level. Entry-level equipment may cost tens of thousands of dollars, while advanced Swiss-type or multi-axis production machines can reach several hundred thousand dollars. For buyers sourcing parts, the more practical focus is total part cost, tolerance requirements, material, setup complexity, and production volume rather than machine purchase price alone.
