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.
Prototype Pricing and Production Pricing Are Two Different Problems
Defense electronics set the volume curve in Melbourne. L3Harris Technologies runs its corporate headquarters and major engineering operations here, Northrop Grumman designs manned aircraft at its Melbourne center and the supplier base that feeds both moves through the same progression: a handful of parts for an engineering build, a few hundred for qualification, then low rate and full rate production. Swiss turning is the rare process that prices sensibly at every step of that ladder, because once a program justifies dedicated bar stock, cycle time rather than setup dominates the unit cost and the price per pin falls hard.
Aviation adds a second demand stream with the same shape. Embraer assembles Phenom 100 and Phenom 300 executive jets at Melbourne Orlando International Airport, and airframe programs consume turned hardware, clevis pins, static fittings and standoffs, in quantities that grow with the delivery schedule. Meanwhile Florida Tech engineering teams and Space Coast hardware startups sit at the opposite end of the curve, ordering five or fifty pieces to prove a design before a production commitment exists.
RivCut serves both ends from our Union City, California shop. Guide bushing support at the cut lets us hold 0.0002 inch TIR concentricity on slender geometry, live tooling and a sub-spindle finish parts in a single setup, and ground shipping reaches Melbourne in 4 to 5 business days with air freight available when a qualification deadline is closer than that.

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.
Swiss Machining Demand Across Melbourne
How demand for small turned parts breaks down across Melbourne.
Defense Electronics & Communications
L3Harris and Northrop Grumman anchor a Melbourne supplier network that buys enormous quantities of small turned interconnect hardware: connector pins, RF contact bodies, coaxial ferrules and shielded sensor housings in beryllium copper, phosphor bronze, brass and 303 stainless. These are classic Swiss parts, under 0.25 inches in diameter with concentricity callouts that decide whether an RF path meets its VSWR budget. We run them bar-fed from 500 to 100,000 plus pieces with full material traceability, and we quote the prototype quantity and the production quantity on the same RFQ so program offices can see the cost curve before LRIP.
Aerospace & Business Aviation
Embraer's Phenom assembly line at Melbourne Orlando International Airport and the broader Space Coast launch economy both consume flight hardware in the Swiss lathe envelope. Clevis pins, fuel system fittings, static port fittings and instrument panel fasteners come off our machines in 2024 and 7075 aluminum, A286, 303 stainless and Ti-6Al-4V. Aviation work carries documentation weight even at the Tier 2 level, so first article inspection reports and EN 10204 3.1 mill certs ship with the parts, and repeat orders run against locked tool offsets so piece 5,000 measures like piece 1.
Semiconductor & Test Instrumentation
Brevard County carries a semiconductor lineage that runs from Harris Semiconductor through Intersil to the Renesas operation in neighboring Palm Bay, and the test and instrumentation firms around it buy micro turned parts constantly. Probe pins, gauge pins, precision dowels, vacuum fittings and PEEK insulators all fit sliding headstock geometry, often at diameters under 0.062 inches where a conventional lathe cannot support the work. Florida Tech research groups order the same part families in prototype counts, and our no minimum policy means a five piece order gets machined, not turned away.
