Swiss Machining
Produce small, complex components with exceptional stability and tolerances as tight as ±0.0001 inches. Ideal for miniature parts, slender geometries, and multi-feature precision work in demanding industries.
Get precision-machined custom CNC components backed by nearly 60 years of manufacturing experience, tight-tolerance capability, and integrated in-house processes. For Toledo, OH manufacturers and OEMs that need dependable repeatability, fast prototype-to-production support, and full traceability, M.A.R.'s Engineering delivers complex parts with consistent quality and streamlined turnaround.
From prototypes to production runs, we machine tight-tolerance components with integrated finishing and quality control.
Produce small, complex components with exceptional stability and tolerances as tight as ±0.0001 inches. Ideal for miniature parts, slender geometries, and multi-feature precision work in demanding industries.
Machine cylindrical parts such as shafts, bushings, fittings, and threaded components with consistent dimensional relationships. Supports prototype quantities and high-volume runs across aluminum, brass, stainless steel, and carbon steel.
Cut conductive materials with intricate outlines, sharp internal corners, and repeatable precision. Well suited for hardened steels, carbide, custom tooling, and components conventional machining cannot easily produce.
Create custom machined parts with advanced 4-axis milling for complex geometries and improved efficiency. Ideal for prototypes, finished parts, and applications requiring precise milled features.
Achieve super-fine finishes up to 4 μin and tolerances up to 0.0001 inches on shafts, pins, tubing, and bar stock for precise fit and smooth performance.
Complete parts in-house with plating, polishing, deburring, powder coating, and light assembly to reduce vendor handoffs, shorten lead times, and deliver ready-to-install components.
M.A.R.'s Engineering manufactures custom CNC components for buyers who need accuracy, repeatability, and dependable production support. From miniature precision parts to high-volume turned components, every project benefits from integrated machining, grinding, EDM, and finishing under one roof. For Toledo, OH manufacturers balancing supplier timelines and strict quality requirements, that means fewer handoffs, better traceability, and faster movement from prototype to full production.
