Swiss Screw Machining
Produce small, intricate turned parts with exceptional stability using sliding-headstock Swiss machining. Ideal for tight tolerances, long slender profiles, and multi-feature components completed in one setup.
M.A.R.'s Engineering delivers CNC Swiss lathe machining for miniature, complex, and tight-tolerance turned parts. From prototypes to high-volume runs, our sliding-headstock process supports long, slender geometries, fine features, and multi-operation parts in one setup, helping manufacturers reduce lead times while maintaining exceptional dimensional consistency and traceability.
Precision machining solutions for miniature, complex, and production-ready turned components across demanding industrial applications.
Produce small, intricate turned parts with exceptional stability using sliding-headstock Swiss machining. Ideal for tight tolerances, long slender profiles, and multi-feature components completed in one setup.
Manufacture micro-scale precision components such as pins, spacers, and contact extensions where conventional machining cannot reliably achieve the required geometry or tolerance control.
Machine precision fittings and connectors with threads, grooves, ports, and complex profiles using Swiss-type and CNC turning processes for consistent sealing and dimensional accuracy.
Produce dimensionally critical bushings and sleeves with tight bore tolerances, fine finishes, and repeatable OD control for demanding mechanical and industrial assemblies.
Create precision shafts and pins with smooth or stepped profiles, grooves, holes, and threaded ends, supported by grinding for ultra-fine finishes and close diameter tolerances.
Manufacture screws, studs, inserts, and standoffs with accurate thread forms and repeatable dimensions for prototype orders and efficient high-volume production runs.
CNC Swiss lathe machining is designed for parts that demand accuracy, repeatability, and efficient multi-operation production. M.A.R.'s Engineering uses sliding-headstock technology to minimize bar deflection, hold tolerances as tight as ±0.0001 inches, and produce complex turned components with drilling, milling, threading, and cross features completed in a single setup.
Supporting prototype and production machining with repeatable quality, tight tolerances, and streamlined in-house manufacturing.

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 a family-run precision manufacturing business ever since. 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. That steady investment allows M.A.R.'s Engineering to support customers with prototype development, precision turned parts, finishing, and production manufacturing under one roof. Guided by a customer service-oriented approach, the company focuses on close tolerances, dependable turnaround, and streamlined project management that helps customers avoid the delays and costs of working with multiple vendors.
CNC Swiss lathe machining is used for small, complex, and high-precision turned parts that require tight tolerances and excellent repeatability. It is especially effective for long, slender components, threaded parts, miniature pins, spacers, fittings, and other parts with multiple features that can be completed in one setup.
