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.
A Space Program Legacy That Still Sets the Tolerance
Huntington Beach manufacturing identity was forged in the 1960s, when Douglas Aircraft opened its Space Systems Center on Bolsa Avenue and built the S-IVB, the Saturn V third stage that pushed Apollo astronauts out of Earth orbit. That campus passed to McDonnell Douglas and then Boeing, which still runs one of its major aerospace and defense sites in the city with thousands of engineers working satellite, launch and space station programs. Sixty years of that work trained the local supply base to treat a 0.0002 inch concentricity callout as normal.
The rest of the city's industry grew up around that standard rather than beneath it. Cambro Manufacturing runs two foodservice equipment plants in Huntington Beach, Quiksilver and a cluster of surf and apparel makers prototype hardware here, and Orange County's medical device corridor sits minutes away in Irvine and Santa Ana. All of them consume small turned components, latch pins, insert fittings, dosing nozzles, fastener specials, in quantities that only a bar fed lathe makes economical.
Swiss turning is the right tool for that mix because the guide bushing supports the stock at the point of cut. A slender titanium pin with a 20 to 1 length to diameter ratio comes off straight, threaded and finished in one cycle, with live tooling and a sub spindle handling flats, cross holes and back work before the part ever leaves the machine.

±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.
What Huntington Beach Teams Send to Our Swiss Lathes
What Huntington Beach buyers actually order, sector by sector.
Space, Satellite & Defense
Boeing's Huntington Beach site and the subcontractor network around it consume exactly the hardware Swiss lathes were built for: electrical contact pins, connector shells, standoffs, RF housings and fastener specials in 303 and 316 stainless, 6061 and 7075 aluminum and titanium. Flight hardware carries traceability requirements down to the bar lot, so RivCut ships full material certs and AS9102 style first article reports with these jobs, and we hold concentricity to 0.0002 inches TIR on mating interfaces that cannot gall or misalign in a vacuum.
Medical Devices
Huntington Beach sits on the edge of one of the densest medical device clusters in the country, with Irvine and Santa Ana OEMs and their contract engineers a short drive up Beach Boulevard. Their Swiss work is the micro end of the catalog: bone screws with cannulated cores, luer fittings, electrode bodies, dental implant components and PEEK insulators under half an inch in diameter. We turn them from implant grade titanium, 316L and 17-4 PH with Ra 16 microinch surfaces as machined, so many features need no secondary grinding or polishing.
Consumer Products & Foodservice Equipment
Cambro Manufacturing builds foodservice equipment from two Huntington Beach plants, and the city's surf and action sports brands, Quiksilver among them, iterate on fins, mounts, leashes and camera hardware season after season. That product development world buys Swiss parts in a different rhythm: latch pins, threaded inserts, ferrules, dispensing nozzles and stainless axles, first as a no minimum prototype batch, then as a 5,000 piece bar fed run once the SKU proves out. Same part number, same machine, no requote drama between the two.
