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.
What Plano Engineering Teams Order From a Swiss Lathe
Start with the part types, because Plano purchasing patterns are unusually specific. A corporate and engineering hub anchored by Toyota North America, Texas Instruments, Ericsson and Boeing Global Services buys turned hardware in three recognizable families: gold plateable contact pins and ferrules for connector and RF assemblies, precision standoffs and guide pins for test and burn-in fixtures, and small fittings and sensor housings for vehicle and aerospace subsystems. Every one of those is a natural Swiss lathe part, small diameter, long relative to its width and needed in the hundreds to tens of thousands.
The semiconductor and telecom side of Collin County sets the tightest specs. Probe card and test socket work tied to the Texas Instruments ecosystem calls for pins at 0.020 to 0.060 inch diameters with concentricity held to 0.0002 inches TIR, while 5G radio and antenna hardware in Ericsson's orbit needs brass and beryllium copper contacts with burr free edges that will not shave plating during insertion. Guide bushing support is what makes those geometries repeatable at production volume.
Defense and aerospace demand fills out the picture. Boeing Global Services is headquartered in Plano and Raytheon operates a major facility one town north in McKinney, and the supplier base feeding both consumes fuel fittings, valve spools, EMI shield standoffs and slender actuator shafts with full material traceability. RivCut runs all of it from our Union City, CA shop and ships ground to Plano in about 2 to 3 business days, with air freight when a line down situation cannot wait.

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.
The Parts Plano Industries Order Most
A sector-by-sector look at Plano Swiss turning demand.
Semiconductors & Electronics
The Texas Instruments footprint across Plano and Richardson supports a dense ecosystem of test, packaging and board level suppliers, and that ecosystem runs on turned micro components. RivCut Swiss machines probe pins, test socket guide pins, alignment dowels and ferrules from beryllium copper, phosphor bronze and 303 stainless at diameters down to 0.020 inches, holding the roundness and surface finish that plating houses need for uniform gold coverage. Bar fed runs from 500 to 100,000 plus pieces keep per part cost predictable across product ramps.
Telecom & Connectivity Hardware
Ericsson runs its North American headquarters in Plano, and the radio, antenna and network equipment engineering around it drives steady demand for RF connector bodies, center contacts, coax ferrules and threaded standoffs. These parts pair tight concentricity with fine threads and knurls, exactly the combination a sliding headstock lathe with live tooling handles in one setup. We turn them from brass, tellurium copper and stainless with concentricity to 0.0002 inches TIR so mated pairs seat without degrading return loss.
Aerospace & Defense
Boeing Global Services headquarters sits in Plano and Raytheon's McKinney campus is a short drive up US 75, which puts a deep bench of defense subcontractors and sustainment engineers in the area. Their Swiss work skews toward flight hardware: fuel system fittings, hydraulic valve spools, clevis pins, EMI standoffs and slender sensor shafts with length to diameter ratios past 20 to 1. RivCut machines these from 17-4 PH, titanium and 7075 aluminum with mill certs, first article inspection reports and lot traceability on every shipment.
