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 Swiss Turned Parts Henderson Companies Buy Most
Start with the purchase orders rather than the industry labels. Around the Black Mountain Industrial complex, where TIMET has produced titanium sponge since the postwar years, the recurring line items are Ti-6Al-4V fuel fittings, clevis pins and sensor housings for the aerospace and battery plants that have grown up alongside it. These are classic Swiss lathe parts, under 1.5 inches in diameter, long relative to their width and intolerant of runout.
A second stream of demand comes from plant equipment. Haas Automation runs its Nevada operations in Henderson, Ocean Spray bottles here and Levi Strauss distributes from here, and all of that machinery consumes dowel pins, valve spools, wear bushings and sanitary fittings on maintenance schedules that punish long lead times. Swiss turning fits this work because the guide bushing supports the bar at the point of cut, so a slender 4140 shaft with a 20 to 1 length to diameter ratio comes off straight without a follow rest or a secondary grind.
RivCut serves Henderson from our Union City, California shop, which puts finished parts on a truck one to two business days from your dock by standard ground. There is no minimum order, so a single prototype for a Touro University Nevada research project and a 50,000 piece bar fed production run for an aerospace supplier both get the same machines and the same inspection reports.

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 Henderson Industries Order Most
A sector-by-sector look at Henderson Swiss turning demand.
Aerospace & Defense
Henderson's aerospace cluster sits unusually close to its raw material, with TIMET's titanium operation anchoring the Black Mountain Industrial complex and Nellis Air Force Base flying daily sorties across the valley. Suppliers feeding airframe, propulsion and defense programs order the small hardware Swiss lathes were built for: fuel system fittings, connector pins, static fittings and valve spools in titanium, 303 stainless and 7075 aluminum. RivCut delivers them with full material traceability, AS9102 style first article reports and concentricity held to 0.0002 inches TIR.
Machine Tools & Plant Equipment
With Haas Automation operating in Henderson, the city has a machine tool literate buyer base that specs turned components the way toolmakers do, by drawing, by tolerance and by material cert. Beyond the machine builders, the Ocean Spray bottling plant and the distribution and process facilities along the Boulder Highway corridor keep a steady replacement demand for precision shafts, coolant fittings, ferrules and bushings. We turn these from 4140, 17-4 PH and bronze, often working from a worn sample and a sketch when the OEM part number is obsolete.
Medical & Dental
Henderson has built a deliberate healthcare economy around Henderson Hospital and the Union Village medical district, and Touro University Nevada trains clinicians a few miles away, which pulls device startups and dental labs into the same orbit. Their Swiss work lives at the micro end of our envelope: bone screws, dental implant bodies, luer fittings and cannulated pins in 316L, titanium and PEEK, finished to Ra 16 microinches as machined so many components skip polishing entirely.
