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.
Certified Small Turned Parts for Mansfield, TX
Documentation is the real spec sheet in Mansfield purchasing. A sub-tier shop feeding the F-35 line at Lockheed Martin Fort Worth or missile programs at Raytheon McKinney cannot accept a turned pin without traceable material certs, and an orthopedic implant builder in the DFW healthcare corridor needs lot control on every bone screw. Quality systems decide who gets the purchase order here, before price ever enters the conversation.
That expectation shapes what Swiss machining looks like for this market. RivCut runs sliding headstock lathes with guide bushing support, holding diameters to ±0.0001 inches and concentricity to 0.0002 inches TIR on bar stock from 0.020 to 1.50 inches. Every shipment can carry EN 10204 3.1 mill certs, AS9102 first article reports and CMM inspection data, so the part arrives in Mansfield with the file your quality manager needs already attached.
Volume flexibility matters too, because the city buys at both ends. Hardware startups clustered around the Mouser Electronics headquarters prototype in tens of pieces, while defense and automotive suppliers near GM Arlington Assembly reorder in the thousands. We run no-MOQ prototypes and bar-fed production from 500 to 100,000 plus pieces, then ship ground in about 3 to 4 business days from our California shop to north Texas.

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 Turned Parts for Mansfield Industries
The work Mansfield engineers quote most often, by industry.
Defense & Aerospace Sub-Tiers
Mansfield sits inside the DFW defense corridor, where machine shops feed Lockheed Martin's F-35 assembly, Bell Textron rotorcraft programs and Raytheon McKinney missile work. The turned hardware in that chain is exactly Swiss territory: guidance housing pins, fuel fittings, ordnance standoffs and slender actuator shafts with L/D past 20 to 1. RivCut turns them from Ti-6Al-4V, 15-5 PH and 7075 aluminum with ITAR-aware handling, full traceability and first article inspection on request.
Electronics & Connector Hardware
With Mouser Electronics headquartered in the city, Mansfield hardware teams live close to the component catalog but still need the metal that mates with it. Contact pins, connector shells, ferrules and threaded standoffs for rugged IoT and oilfield sensor products are classic Swiss work: single-setup parts off the sub-spindle with live tooling for cross-drilled and flatted features. We hold Ra 16 microinch finishes as machined on brass, phosphor bronze and 303 stainless, from a 50-piece prototype run to bar-fed lots in the tens of thousands.
Medical & Orthopedic Devices
Orthopedic implant manufacturers and surgical instrument developers across the DFW healthcare corridor buy the smallest and most regulated turned parts in the region. Bone screws, dental implant bodies, luer fittings and cannulated guide pins demand biocompatible bar stock, lot traceability and surface finishes that pass incoming inspection without argument. RivCut Swiss turns medical-grade titanium, 316L and PEEK to ±0.0001 inches, with the documentation package built for ISO 13485 supplier audits.
