Our Custom Swiss-Type Turned Components & Parts Services

Precision-machined turned parts for miniature, threaded, connector, and high-tolerance component applications.

Miniature Components

Manufacture of miniature precision components, micro-pins, spacers, and complex small-diameter parts using Swiss machining and EDM for ultra-tight tolerances and intricate geometries.

Threaded Parts

Production of precision threaded fasteners, inserts, studs, and standoffs with accurate thread forms, repeatable dimensions, and support for both custom and standard profiles.

Fittings Connectors

Custom fittings and connectors with threads, grooves, ports, and sealing features completed in fewer setups for strong dimensional control and reliable functional performance.

Bushings Sleeves

Precision bushings and sleeves produced with tight bore tolerances, fine surface finishes, and material options suited for wear resistance and accurate assembly fit.

Shafts Pins

High-precision shafts and pins manufactured with turning and centerless grinding for close diameter control, smooth finishes, and ready-to-install performance.

Swiss Screw Machining

Swiss-type CNC machining for long, slender, and complex turned parts requiring multiple operations in one setup, reduced deflection, and tolerances as tight as ±0.0001 inches.

Ultra-Tight Tolerances

Precision Parts Built For Critical Performance

Custom Swiss-type turned components are ideal when part geometry, diameter, and tolerance leave little room for error. M.A.R.'s Engineering combines Swiss machining, screw machining, EDM, grinding, and finishing in one facility to reduce handoffs and maintain control from raw material to final inspection. That means faster prototype-to-production transitions, consistent repeatability, and dependable quality for industries where dimensional accuracy and traceability matter most.

Frequently Asked Questions

What does Swiss machining mean?

Swiss machining is a precision CNC turning process that uses a sliding headstock and guide bushing to support bar stock right at the cutting point. This setup reduces deflection and vibration, making it ideal for small-diameter, long, slender, or highly detailed parts. It allows multiple operations in one setup and can hold tolerances as tight as ±0.0001 inches.
