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.
Small Turned Parts for Virginia Beach's Defense Supply Chain
Naval aviation and shipbuilding define manufacturing across Virginia Beach and the wider Hampton Roads region. Naval Air Station Oceana runs the Navy's East Coast F/A-18 fighter operations, Naval Station Norfolk is the largest naval base in the world and Joint Expeditionary Base Little Creek anchors the region's expeditionary forces. Every one of those installations, along with the contractors that support them, consumes small turned hardware by the thousands, from avionics connector pins to hydraulic fittings, machined round, concentric and burr free at rates a manual lathe cannot hold.
The supply chain behind those programs reaches well beyond the bases. Huntington Ingalls builds carriers and submarines up the peninsula at Newport News, while BAE Systems and Norfolk Naval Shipyard keep the surface and subsurface fleet running. STIHL Inc. adds a very different demand, manufacturing outdoor power equipment at its US headquarters in Virginia Beach. Swiss turning fits all of it because the guide bushing supports the bar right at the cutting point, so a 5 inch valve spool at 0.30 inch diameter leaves the machine straight rather than tapered, and a fuel fitting holds its seat concentricity across a full production lot.
Engineered for Micro-Precision & High Volume
From single medical prototypes to automated 100,000+ piece production runs — built for zero defect manufacturing.
±0.0001" Micro Tolerance
Holding ultra-precise concentricity, diameter, and thread pitch tolerances on slender pins, shafts, and medical implants where standard lathes fail.
Single-Setup Completion
Multi-axis live tooling and sub-spindles handle turning, off-center milling, cross-drilling, hex broaching, and thread whirling with zero secondary setups.
Superior Ra 16 Surface Finish
Rigid guide bushing support eliminates chatter and micro-vibration, consistently producing mirror-smooth Ra 16 µin (0.4 µm) turned surfaces as-machined.
Lights-Out Production Savings
Automatic bar feeders and continuous chip management allow 24/7 un-attended operation, dramatically lowering unit costs for mid-to-high volume orders.

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.
How Virginia Beach Industries Use Swiss Turned Parts
Three local sectors, three very different turned parts. Here is what we machine for Virginia Beach teams.
Naval Aviation & Defense
Naval Air Station Oceana flies the Navy's East Coast F/A-18 Super Hornet wings, while Naval Station Norfolk and Joint Expeditionary Base Little Creek sustain a constant maintenance and upgrade tempo across the fleet. That work runs on small turned metal: connector and contact pins for avionics harnesses, threaded standoffs, hydraulic fittings and proximity sensor housings. RivCut Swiss turns these from 303 and 316 stainless, Ti-6Al-4V and aluminum with full material traceability, first article reports and the passivation or anodize saltwater service demands. Export-controlled part data is handled under our DDTC registration, as Hampton Roads naval programs require.
Shipbuilding & Marine Systems
Carrier and submarine construction at Huntington Ingalls in Newport News, plus surface fleet overhaul at BAE Systems Norfolk Ship Repair and Norfolk Naval Shipyard, keeps a steady appetite for small shipboard components. Valve spools, ferrules, wear bushings, gauge pins and instrument fittings for shipboard hydraulic, fuel and pneumatic systems all sit inside Swiss lathe geometry. We machine them from 17-4 PH and 316L stainless, Monel and naval bronze, often from a sample and a print, with the passivation and marine-grade coatings shipboard service requires.
Power Equipment & Hardware
STIHL Inc. runs its US headquarters and manufacturing plant in Virginia Beach, building outdoor power equipment whose fuel systems, valves and drive assemblies use exactly the kind of small turned parts Swiss lathes produce in volume. Beyond STIHL, the Port of Virginia moves material handling and marine hardware, and Old Dominion University and the 757 Makerspace feed a growing base of hardware founders prototyping sensor and enclosure components. RivCut covers the full range, single prototype through 100,000 piece bar-fed runs, machining fuel fittings, threaded shafts, bushings and knurled fasteners from brass, 12L14, aluminum and stainless.
