What Is Swiss CNC Machining?
Swiss CNC machining (also known as Swiss screw machining or sliding headstock turning) feeds bar stock through a stationary guide bushing directly adjacent to the cutting tool. Because the material is supported right where the cut happens, deflection and vibration are eliminated — allowing ultra-tight tolerances, micro features, and length-to-diameter aspect ratios over 20:1 that conventional CNC lathes cannot achieve.
Bar Stock Feeds Through Guide Bushing
The raw bar feeds through a carbide-lined guide bushing, providing zero-clearance support right next to the cutting insert.
Sliding Headstock Moves Along Z-Axis
Instead of moving the cutting tool along the part, the headstock advances the bar past fixed gang tooling, maintaining maximum rigidity.
Live Tooling & Sub-Spindle Dual Machining
Cross-milling, axial drilling, threads, and back-side features are completed in a single setup before parting off the finished part.
Two Kinds of Swiss Buyers in West Palm Beach
Talk to enough engineers around West Palm Beach and a split becomes obvious. On one side sit the supply chains feeding Pratt & Whitney's jet engine campus, Sikorsky's Development Flight Center and Lockheed Martin programs across northern Palm Beach County. Those buyers order turned hardware in qualified, repeating lots: fuel system fittings, instrumentation pins and lockwire-drilled fasteners with first article reports, material certs and revision control on every release. What they need from a Swiss shop is boring consistency, piece 8,000 measuring like piece 8.
On the other side are the startups and labs. The dental implant cluster that grew up around Biomet 3i in Palm Beach Gardens, spinouts orbiting Scripps Research and the Max Planck Florida Institute in Jupiter, and marine electronics builders near the Port of Palm Beach all prototype in tens, not thousands. They need a shop that will run 25 titanium implant bodies or a handful of PEEK insulators without a tooling charge lecture, then scale the same program to production when funding lands.
Swiss turning fits both because the guide bushing supports the bar at the point of cut, so a 3 inch long shaft at 0.187 inch diameter comes off straight, concentric to 0.0002 inches TIR and finished near Ra 16 microinches as machined. Ground shipments from our Union City, CA shop reach South Florida in 4 to 5 business days, with air freight available when a test cell or a surgical schedule cannot wait.

DFM Tips for Swiss Turned Parts
Optimize your 3D CAD models and drawings for maximum Swiss machining efficiency.
1. Precision Ground Bar Stock
Because the bar slides through a guide bushing, use h8 diameter tolerance precision ground bar stock to prevent binding or loose play.
2. Thread Relief Grooves
Provide a thread relief necking groove at thread shoulders (minimum 1.5x thread pitch) to allow clean single-point thread tool retraction.
3. Corner Radii & Chamfers
Specify internal corner radii of at least R 0.010" (0.25 mm) and external 45° lead-in chamfers to ease automated tool engagement and deburring.
West Palm Beach Applications for Swiss Turning
The West Palm Beach part families that belong on a Swiss lathe.
Jet Propulsion & Defense Aerospace
Pratt & Whitney develops and tests engines, including military propulsion programs, on its sprawling campus in northern Palm Beach County, with Sikorsky flight test operations next door and Lockheed Martin work threaded through the region. The supplier tiers under those programs consume small turned parts constantly: fuel nozzle components, rig instrumentation fittings, thermocouple bosses and test cell adapter hardware. RivCut Swiss turns them from Inconel 718, 17-4 PH, A286 and titanium with lot traceability, AS9102-style first article reports and mill certs on every shipment.
Medical, Dental & Life Science Devices
Palm Beach Gardens has been a dental implant manufacturing address since the Biomet 3i era, and the Jupiter biotech corridor around Scripps Research and the Max Planck Florida Institute keeps generating instrument and device work. This is core Swiss territory: implant bodies and abutment screws in Ti-6Al-4V ELI, bone screws with single-setup thread whirling geometry, cannulated pins, luer fittings and electrode housings under half an inch in diameter. We run validation quantities for regulatory submissions and scale to bar-fed production lots with full material traceability.
Marine & Yacht Systems
The waterfront is its own economy here. Safe Harbor Rybovich refits superyachts on the West Palm Beach waterfront, the Port of Palm Beach moves cargo out of Riviera Beach and a dense network of marine electronics, hydraulics and rigging shops supports both. Salt water is unforgiving to small hardware, so this work leans on 316 stainless, Monel and bronze: valve spools for steering hydraulics, sensor ferrules, antenna connector pins, standoffs and custom fittings that OEM catalogs stopped carrying a decade ago. We machine replacements to print or reverse engineered from a worn sample.
