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.
The Turned Parts Gainesville Companies Actually Order
Start with the purchase orders, not the brochure. Gainesville's device makers buy titanium and 316L bone screws with cortical and cancellous thread forms, cannulated guide pins, tapered implant posts and the luer and cannula fittings that surround surgical instrumentation. Exactech builds orthopedic implants here, RTI Surgical works in surgical implant and biologics territory and AxoGen commercializes nerve repair products, so the local demand curve is dominated by small turned medical hardware where a burr or a taper is a rejected lot, not a rework note.
A second stream comes off campus. The University of Florida runs one of the largest research enterprises in the state, and its engineering labs, biotech spinouts and UF Innovate startups prototype fluidics manifold fittings, electrode bodies, dowel pins and sensor housings in quantities from 5 pieces to 5,000. Swiss turning fits both streams because the guide bushing supports the bar at the cutting point, so a 0.062 inch diameter electrode pin or a 20:1 length-to-diameter bone screw blank comes off straight, concentric and finished near Ra 16 microinches without a grinding operation.
RivCut serves Gainesville from Union City, California. Machined lots reach Florida in 4 to 5 business days by ground, faster by air when a validation build or a surgeon demo cannot slip. There is no minimum order, and bar-fed production scales from first articles to 100,000 plus pieces on the same program.

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.
The Parts Gainesville Industries Order Most
A sector-by-sector look at Gainesville Swiss turning demand.
Orthopedic & Surgical Implants
Exactech's implant lines and RTI Surgical's implant and biologics work sit at the center of Gainesville manufacturing, and the supplier tiers around them buy the classic Swiss menu: bone screws in Ti-6Al-4V ELI and 316L, cannulated pins gun-drilled on the sub-spindle, locking screw blanks and instrument shafts with L/D ratios past 20:1. We turn these single-setup with live tooling for hex and Torx drives, ship full material traceability and hold thread form and cannulation concentricity to medical print tolerances.
Biotech & Nerve Repair Devices
AxoGen's nerve repair portfolio and the biotech companies spun out of University of Florida research need the delivery-side hardware around their biologics: luer fittings, cannula hubs, micro ferrules and PEEK or 316L fluidic connectors under 0.25 inches in diameter. These are low-mass parts where deburring by hand would destroy the feature, so the as-machined Swiss finish matters. We run them from 316L, titanium, PEEK and Ultem with lot control suitable for device history records.
UF Spinoff Electronics & Aerospace
Gainesville's aerospace and electronics activity flows through University of Florida spinoffs and UF Innovate startups building sensors, RF hardware and small flight components. Their turned-part demand is connector pins, contact pins, gold-plate-ready standoffs, valve spools and slender shafts in 303 stainless, brass and 7075 aluminum. RivCut quotes these instantly from a STEP file, runs 5 prototypes this month and 5,000 production pieces next quarter without retooling the program.
