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.
From First Article to Full Rate for Dallas Programs
Volume is the defining variable in Dallas purchasing. Lockheed Martin ships more than 100 F-35s a year out of Fort Worth, Raytheon builds missile guidance and radar systems in McKinney and Texas Instruments runs 300mm wafers in Richardson, so the suppliers feeding those lines cannot treat 10 pieces and 10,000 pieces as separate vendors. Swiss turning collapses that gap. The same program that cuts your qualification lot keeps running unattended off 12 foot bar stock when the blanket order lands, which is why per-piece pricing on a connector pin can drop 60 to 80 percent between prototype and production without a requote fight.
Geometry is the other reason DFW work fits a sliding headstock lathe. Guidance electronics, electronic warfare modules and chip-test fixtures consume pins, contacts and ferrules under 0.25 inches in diameter, often with length-to-diameter ratios past 20 to 1. The guide bushing supports the bar at the point of cut, so a slender gold-plated contact pin or a titanium bone screw blank comes off straight and concentric to 0.0002 inches TIR, with live tooling adding flats, cross holes and slots in the same setup.
Shipping does not erase the economics. Ground transit from our California shop reaches Dallas in 3 to 4 business days, and air freight is always available when an L3Harris line in Greenville or an Integer Holdings build in Plano cannot wait. Scheduled releases against a blanket order mean parts arrive as your assembly line consumes them, not as one inventory-heavy drop.

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 Dallas
How demand for small turned parts breaks down across Dallas.
Defense & Aerospace
The DFW defense corridor buys small turned parts at flight-program scale. Raytheon missile guidance assemblies in McKinney, Bell Textron rotorcraft programs and the Lockheed Martin F-35 supply chain in Fort Worth all consume connector pins, seeker component hardware and hydraulic fittings that carry AS9102 first article and full traceability expectations. RivCut Swiss turns them from 303 and 17-4 PH stainless, 2024 and 7075 aluminum and Ti-6Al-4V in an ITAR-registered shop, with FAI reports and mill certs attached from the qualification lot onward.
Semiconductor & Electronics
Texas Instruments invented the integrated circuit in Dallas, and its Richardson fabs plus Qorvo's RF operations keep the metroplex dense with test and packaging engineering. That work runs on Swiss-turned hardware: test-socket contact pins, probe bodies, RF connector center conductors and gas-delivery ferrules in brass, beryllium copper, tellurium copper and 316 stainless. We hold the sub-0.001 inch concentricity these parts need and scale from a 25 piece fixture build to bar-fed runs in the tens of thousands as a test cell replicates.
Medical Devices
Integer Holdings machines components for implantable devices in Plano, and UT Southwestern Medical Center feeds a steady stream of clinical-stage device prototypes across the metroplex. Swiss machining is the native process for this catalog: bone screw blanks, lead connector pins, luer fittings and electrode bodies in titanium, 316L and PEEK, mostly under 0.5 inches in diameter with Ra 16 microinch finishes as machined. Lot-level material traceability ships with every order, and no MOQ means a surgeon-inventor prototype gets the same process as a validated production release.
