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.
Fast Freight to Junction City, Small Parts Done Right
Ogden earned the name Junction City because freight has always moved through it, and that still matters when a program office at Hill Air Force Base or a buyer at Northrop Grumman in Roy needs turned hardware on a date certain. Ground shipments from our California shop reach the Wasatch Front in 2 to 3 business days via the same I-80 and I-15 corridors that built the city, and air expedite compresses that to next day when a line-down situation demands it. For a purchasing team juggling depot maintenance schedules or Sentinel program milestones, transit time you can plan around is worth as much as the machining itself.
The parts themselves are classic Swiss lathe work. The Ogden Air Logistics Complex sustains the F-35, F-16 and A-10 fleets, and sustainment consumes small turned components in steady volumes: clevis pins, bushings, fittings and fasteners that must be round, concentric and documented. Williams International builds turbofan engines on the west side of town, Autoliv produces safety systems up the corridor and Fresenius Medical Care runs dialysis product manufacturing in the city. Every one of those operations, plus the supplier network around Business Depot Ogden, buys the diameters and length ratios that a guide bushing machine handles better than anything else.

±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.
Ogden Industries That Run on Swiss Turning
Real part families we quote for Ogden companies.
Defense & Air Force Sustainment
Depot maintenance at the Ogden Air Logistics Complex and the contractor ecosystem around Hill Air Force Base generate constant demand for small turned hardware with full traceability. RivCut Swiss machines clevis pins, threaded standoffs, bushings and hydraulic fittings from 303 and 17-4 PH stainless, 4140 and titanium, shipping mill certs and first article inspection reports with the parts. Northrop Grumman's Roy campus and its Sentinel supply base add long-cycle production work where locked pricing and repeatable lots matter more than any single delivery.
Aerospace Propulsion & Systems
Williams International builds small turbofan engines in Ogden, and turbine engines are dense with Swiss geometry: fuel system fittings, metering components, sensor housings and slender shafts where concentricity to 0.0002 inches TIR decides whether the part seals. We run these from Inconel 718, 15-5 PH, titanium and 6061, single setup with live tooling and sub-spindle so the milled flats, cross holes and back-side features come off finished. Suppliers feeding the engine plant get the same bar-fed economics from 500 pieces to 100,000.
Medical & Outdoor Products
Fresenius Medical Care manufactures dialysis products in Ogden, and the city's outdoor industry cluster, anchored by ENVE Composites and fed by Weber State University engineering graduates, prototypes hardware constantly. Swiss turning covers both ends: luer fittings, cannulated pins and 316L instrument components for medical work, plus ferrules, axle hardware and anodize-ready aluminum fittings for bike and gear companies. No MOQ means a first article run of five pieces is a normal order, not a favor.
