Swiss Machining
Swiss-type machining produces miniature medical parts with complex geometries, long slender profiles, and tolerances as tight as ±0.0001 inches using supported bar stock and multi-operation capability.
Custom Medical Machining Services from M.A.R.'s Engineering deliver tight-tolerance components for demanding medical applications, from prototypes to production. With nearly 60 years of precision machining experience, in-house Swiss machining, EDM, grinding, and finishing, we help medical manufacturers source complex parts with consistent quality, traceability, and streamlined lead times.

Precision machining solutions for miniature, complex, and production-ready medical components.
Swiss-type machining produces miniature medical parts with complex geometries, long slender profiles, and tolerances as tight as ±0.0001 inches using supported bar stock and multi-operation capability.
Wire EDM supports conductive medical materials and intricate part profiles, making it ideal for sharp internal corners, detailed features, and hardened alloys that challenge conventional machining methods.
CNC turning delivers repeatable cylindrical medical components such as pins, bushings, fittings, and threaded parts with strong dimensional control across prototype and production quantities.
Centerless grinding achieves ultra-fine finishes and diameter tolerances up to 0.0001 inches for medical shafts, pins, and tubing where fit, smoothness, and consistency are critical.
Miniature precision component manufacturing supports micro-pins, spacers, contact extensions, and other small-scale medical parts that require close tolerances and complex multi-feature geometry.
In-house finishing, polishing, plating, deburring, and light assembly help deliver medical components that are production-ready while reducing outside vendor coordination and lead-time risk.
M.A.R.'s Engineering supports medical manufacturers with custom-machined components built for accuracy, repeatability, and production efficiency. From miniature titanium parts to precision-ground pins and threaded features, our in-house capabilities reduce handoffs and help maintain dimensional consistency throughout the job. With Swiss machining, EDM, CNC turning, grinding, and finishing under one roof, we simplify sourcing while supporting traceability and dependable quality.

From prototypes to high-volume runs, equipment and workflows support efficient growth without sacrificing precision.
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 manufacturer ever since. Over the decades, the company expanded from screw machining into broader in-house capabilities, adding multi-spindle production, CNC machining, Wire EDM, centerless grinding, finishing, and light assembly. That steady investment allows us to support customers who need close-tolerance parts without managing multiple vendors. Our vision is simple: deliver dependable machining quality, responsive service, and efficient production support for complex components, whether a customer needs prototype quantities, repeat production, or a complete manufacturing partner for critical medical applications.
Medical implants commonly use commercially pure titanium such as Grade 2 and titanium alloys such as Ti-6Al-4V, often Grade 5 or implant-focused Grade 23. The right grade depends on the application, required strength, corrosion resistance, and biocompatibility standards. Machining partners should follow the customer’s specified material callout, certification, and traceability requirements throughout production.
