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 Glendale's Packaging and Defense Cluster
Beverage packaging is the dominant manufacturing cluster in Glendale. Mark Anthony Brewing fills White Claw at one of the largest beverage plants ever built in North America, Red Bull bottles its North American product nearby and Ball Corporation forms the aluminum cans that feed both. Lines like these run at hundreds of cans per minute, which means fill valves, changeover pins, seamer spindles and sensor probes wear on a schedule and a stopped line burns money by the hour. Swiss turning is how the replacement parts get made round, concentric and identical, run after run.
West of town, Luke Air Force Base gives Glendale a second precision economy. The 56th Fighter Wing trains F-35 pilots there, and the maintenance, ground support and simulator supply chains around the base consume connector pins, contact pins, fasteners and fittings that carry aerospace documentation expectations. Add the Loop 303 industrial corridor pulling new plants into the West Valley and Midwestern University anchoring medical and dental programs on the city's north side, and Glendale buys a wider range of micro turned parts than its packaging headline suggests.
The guide bushing on a sliding headstock lathe supports the bar right at the tool, so a 5 inch long changeover shaft at 0.25 inch diameter comes off straight instead of tapered, and a 0.040 inch contact pin holds its diameter to a tenth. That is the geometry Glendale's plants and suppliers keep ordering.

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 Glendale Industries Use Swiss Turned Parts
Three local sectors, three very different turned parts. Here is what we machine for Glendale teams.
Beverage Packaging & Bottling
Filling and canning equipment at the Mark Anthony Brewing, Red Bull and Ball Corporation scale is built from small precision components that wear continuously: valve spools in fill valves, ferrules and nozzle tips in product paths, proximity sensor housings on every station and slender changeover shafts swapped at each SKU change. RivCut Swiss turns replacements and upgrades from 316L stainless, PEEK and Delrin for product contact and 17-4 PH for structural wear parts, often working from a worn sample and a sketch so maintenance planners are not hostage to OEM lead times.
Defense & Aerospace Suppliers
Luke Air Force Base hosts the largest F-35 training operation in the world under the 56th Fighter Wing, and the contractor ecosystem around it, from ground support equipment builders to simulator and avionics suppliers, buys turned hardware in steady volumes. Connector pins, contact pins, clevis pins and fuel system fittings all sit squarely in Swiss lathe territory. RivCut machines them from 303 stainless, 2024 and 7075 aluminum and Ti-6Al-4V with full material traceability, first article inspection reports and concentricity held to 0.0002 inches TIR.
Medical & Dental
Midwestern University's Glendale campus trains physicians, dentists and pharmacists, and the Phoenix West Valley medtech scene it feeds prototypes and produces small devices constantly. This is the micro end of Swiss work: bone screws, dental implant components, luer fittings, cannulated pins and electrode bodies under 0.5 inches in diameter, machined from 316L, titanium and PEEK with Ra 16 microinch finishes as machined. No minimum order means a Glendale device startup can order 5 pieces for a design review and scale the same drawing to a 10,000 piece bar fed run without requoting the process.
