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 Blanket Order in Garland
Swiss turning economics reward exactly the kind of buying Garland does. The city carries one of the largest manufacturing bases in Texas, with major plants run by Raytheon, Kraft Heinz, Atlas Copco, Rheem and Resistol Hats, plus the metal and plastics shops that feed them. Those operations do not buy one turned part at a time. They buy connector pins by the thousand, valve components by the tray and sensor housings on standing reorder, which is the volume band where a bar-fed sliding headstock lathe beats a chucker on both price and consistency.
The path we run for Garland teams starts small on purpose. First articles come off the same machine that will run production, so a 25 piece validation lot proves out the exact process, not a stand-in. Once the print is frozen, live tooling and a sub-spindle finish each part complete in one setup, milled flats, cross holes and back work included, and the unit price falls hard as bar stock quantities climb from 500 to 10,000 and beyond.
Distance barely enters the math. Ground transit from our California shop to the central US runs 3 to 4 business days, and bar-fed production schedules are predictable enough to plan releases around. For a line-down emergency at a Garland plant, expedited machining and air freight compress the whole cycle to days.

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 Garland
How demand for small turned parts breaks down across Garland.
Defense Electronics & Aerospace
Raytheon has run defense electronics production in Garland for decades, and the supplier network around it across the Dallas area consumes precision turned interconnect hardware in steady volume: contact pins, connector pins, RF standoffs and ferrules in brass, beryllium copper and 303 stainless. These are classic Swiss parts, small diameters, tight concentricity and plating-ready finishes. RivCut is DDTC registered and turns them with full material traceability and first article reports for programs that require documentation at every tier.
HVAC, Water Heating & Industrial Equipment
The Rheem water heater plant and Atlas Copco's Garland operation sit in an equipment-building cluster that wears through small turned components on production schedules: valve spools, orifice fittings, thermowell bodies and slender actuator shafts. Guide bushing support is what makes the long thin ones practical, a shaft with a length over 20 times its diameter comes off straight instead of tapered. We machine these from brass, 304 and 17-4 PH to print, often working from a worn sample and a sketch when no drawing exists.
Food & Consumer Products Manufacturing
Kraft Heinz runs one of its larger plants in Garland and Resistol Hats has made headwear here for a century, and both kinds of operations depend on maintenance and OEM spares that fit Swiss geometry: dosing nozzles, proximity sensor housings, wear bushings and washdown-rated fittings in 316L. Production lines do not wait on OEM part numbers, so we quote replacements from a sample part, machine them without minimums and hold Ra 16 microinch finishes as machined so food-contact surfaces need no secondary polishing.
