What Is CNC Swissing?

CNC Suisse- également connu sous le nom Usinage à vis suisse ou Swiss Turning—is a specialized manufacturing technologie designed to produce small, complex cylindrical parts with ultra-tight tolerances. Originating in Switzerland in the 19th century for watchmaking, it has evolved into an automated CNC process that excels at parts where precision and consistency are non-negotiable.​

Le Aperçu du processus revolves around a unique design: Unlike conventional turning (where the workpiece is held at one end), CNC Swissing uses a bague guide—a precision sleeve that supports the workpiece close to the cutting tool. This minimizes vibration and deflection, even for long, parties minces (Par exemple, medical needles, electronics pins).​

To explain “Comment ça marche” simply: The workpiece is fed through the guide bushing and rotated by a spindle. Outils de coupe (mounted on a sliding turret or gang tool post) move along multiple axes (X, Oui, Z, and often C for rotational control) to shape the part. The guide bushing ensures the cutting tool acts on the workpiece’s unsupported length with minimal flex—enabling tolerances as tight as ±0.001mm.​

En bref, CNC Swissing is the go-to for “micro-precision” parts: If a component is small (typically ≤25mm diameter), long (length-to-diameter ratio ≥10:1), or requires complex features (Par exemple, multiple threads, machines à sous, cross-holes), CNC Swissing delivers results conventional machining can’t match.

The CNC Swissing Process

Notre processus étape par étape is optimized to leverage the unique advantages of Usinage à vis suisse—minimizing vibration, maximizing precision, and streamlining production:​

1. Conception et modélisation CAO: Nous commençons par examiner votre modèle CAO (ou en créer un à partir de croquis/spécifications). Our engineers optimize the design for CNC Swissing—e.g., ensuring features like cross-holes are accessible with live tooling and the part’s length-to-diameter ratio works with the guide bushing. For micro-parts, nous utilisons la simulation 3D pour tester la faisabilité.​

2. Programmation de came: Le modèle CAO est importé dans le logiciel CAM (Mastercam Swiss, Gibbscam) pour générer optimisé chemins d'outils. We program sequential operations (turning → drilling → tapping → milling) and synchronize tool movements with spindle rotation. Pour les courses à volume élevé, we add in-line inspection triggers (Par exemple, check diameter after turning).​

3. Configuration et calibrage: The workpiece (usually a bar stock) is loaded into the machine’s spindle and fed through the bague guide (calibrated to within ±0.0005mm of the spindle axis). Cutting tools are mounted on the turret/gang tool post, et systèmes de refroidissement are activated. We run a test part to verify tolerances and adjust tool offsets if needed.​

4. Exécution d'usinage: La machine exécute le programme CAM, with the guide bushing supporting the workpiece during cutting. Live tooling adds complex features (Par exemple, cross-holes, fils de discussion) sans repositionner la pièce. Our operators monitor the process via CNC software, adjusting spindle speed/feed rate for material-specific needs (Par exemple, slower speeds for titanium).​

5. Inspection après usinage: Les pièces sont soumises à des contrôles rigoureux contrôle de qualité—Inspection à 100 % des composants critiques (Par exemple, dispositifs médicaux) using CMMs and optical comparators. Nous vérifions les dimensions, tolérances, and surface finish against CAD data. Pour les courses à volume élevé, in-line vision systems flag defects in real time.​

Swiss Screw Machine Operation Review: After production, we analyze tool wear and process data to refine future runs—ensuring consistent quality for repeat orders.

Key Advantages of CNC Swissing

Compared to conventional turning or milling, CNC Suisse offers unique benefits for small, parties complexes:​

1. Haute précision: With tolerances as tight as ±0.0005mm, it produces parts that fit seamlessly—critical for micro-medical components (Par exemple, Conseils de cathéter) or electronics pins where even tiny gaps cause failure.​

2. Cohérence et répétabilité: The guide bushing minimizes vibration, and CNC automation ensures every part is identical—even for high-volume orders (Par exemple, 500,000 brass terminals).​

3. Géométries complexes: Live tooling and multi-axis control enable machining of features like cross-holes, fils de discussion, and undercuts in one setup—eliminating the need for secondary operations (and associated errors).​

4. Temps de configuration réduit: Automated tool changers and bar-feeder systems let us run unattended for hours—cutting setup time by 60–80% compared to conventional machining.​

5. Increased Efficiency: Usinage à grande vitesse (jusqu'à 15,000 RPM for aluminum) and unattended operation reduce per-part cycle time. For high-volume parts, we achieve production rates of 10–50 parts per minute.​

6. Versatilité: It works with almost any material (métaux, plastiques, exotics) and handles parts from 0.5mm to 25mm diameter—making it a one-stop solution for diverse small-component needs.​

7. Rentabilité: While upfront costs are higher than conventional machining, reduced secondary operations, déchets minimaux (coupure de précision), and fast cycle times lower long-term costs—especially for high-volume orders.​

8. Tolérances étroites: The guide bushing’s support is unmatched for long, parties minces (Par exemple, 20mm-long needles with 1mm diameter)—conventional turning would cause deflection, but CNC Swissing maintains ±0.001mm tolerance.​

High-Quality Surface Finish: Minimal vibration and sharp cutting tools produce surface finishes as smooth as Ra 0.1μm—eliminating the need for post-machining polishing in many cases.

Applications de l'industrie

CNC Suisse is indispensable across industries that rely on small, composants de haute précision. Voici ses applications les plus courantes:

Par exemple, in the medical industry, our CNC-swissed hypodermic needles (0.8diamètre mm, ±0.001mm tolerance) ensure consistent fluid flow and minimal patient discomfort. En électronique, our brass PCB pins (1diamètre mm) fit seamlessly into dense circuit boards—critical for miniaturized devices like smartphones.

Advanced Manufacturing Techniques in CNC Swissing

To maximize the precision and efficiency of CNC Swissing, we leverage specialized techniques d'usinage and optimize processes for small, parties complexes:​

• Swiss Turning with Live Tooling:​

• The core technique of CNC Swissing—combines conventional turning (shaping outer diameters) avec outils en direct (forets, tapissements, mills mounted on the turret). This lets us add cross-holes, fils de discussion, or slots in one setup—eliminating secondary operations. Par exemple, we can machine an electronics pin with a threaded end, a cross-hole for wiring, and a knurled section in a single cycle.​

• Nous utilisons gang tooling (multiple tools mounted side-by-side) pour des pièces simples (Par exemple, straight pins) to reduce tool change time, et turret tooling (rotating tool post) pour des pièces complexes (Par exemple, medical screws with multiple features).​

• Micro-Machining for Tiny Parts:​

• For components ≤1mm diameter (Par exemple, micro-needles), Nous utilisons micro-live tooling (0.1mm-diameter drills/mills) and ultra-low feed rates (5–10 mm / min) to avoid tool breakage. We also use air-cooled spindles (au lieu de liquide de refroidissement) for micro-parts to prevent residue buildup on small features.​

• Bar Feeding and Unattended Operation:​

• Nous utilisons automatic bar feeders (capacity up to 3 mètres) to load long bar stock into the machine—enabling unattended operation for 8–12 hours. This is critical for high-volume orders (Par exemple, 500,000 electronics pins) as it reduces operator time and increases efficiency.​

• Optimisation du chemin d'outil:​

• CAM software generates chemins d'outils that minimize tool travel and prioritize features by accessibility. Par exemple, we machine outer diameters first (to stabilize the part), then add inner features (Par exemple, trous) and finally complex features (Par exemple, sous-dépouille). For exotic metals like inconel, Nous utilisons trochoidal turning (a circular tool path) to distribute cutting force evenly and extend tool life.​

• Sélection d'outils de coupe:​

• Outils en carbure: Pour la plupart des métaux (acier, aluminium, laiton)—durable and cost-effective for high-volume runs. We use coated carbide (Tialn) for heat resistance.​

• Diamond-Coated Tools: Pour les non-métaux (Jeter un coup d'œil, acrylique) and exotic metals—prevent chipping and ensure smooth surface finishes.​

• Outils en céramique: For high-temperature alloys (inconel, tantale)—withstand heat up to 1,200°C, reducing tool changes by 50%.​

• Systèmes de liquide de refroidissement:​

• Flood Coolant: For metal machining—delivers high-pressure coolant (50–80 bar) to the cutting zone via directed nozzles. This reduces heat distortion and flushes away chips (critical for small parts where chips can get stuck in cross-holes).​

• Mist Coolant: For plastics and micro-parts—atomizes coolant into a fine mist to avoid residue buildup. Ideal for PEEK or acrylic, where excess coolant can warp the part.​

• Guide Bushing Optimization:​

The guide bushing is the “secret” to CNC Swissing precision—we select bushings based on part diameter (clearance ≤0.001mm) et matériel. For soft metals (cuivre), we use carbide bushings to prevent wear; for hard metals (titane), we use diamond-coated bushings for longer life. We also lubricate bushings with high-pressure oil to reduce friction between the part and bushing.

Études de cas: CNC Swissing Success Stories

Notre CNC Swissing services have solved complex small-component challenges for clients across medical, électronique, et industries aérospatiales. Vous trouverez ci-dessous deux Projets réussis showcasing our expertise in micro-precision and high-volume production:​

Étude de cas 1: Medical Device Company (Stainless Steel Hypodermic Needles)​

• Défi: Le client avait besoin 1,000,000 stainless steel hypodermic needles monthly (0.8diamètre extérieur mm, 0.5mm inner diameter, ±0.001mm tolerance). The needles required a sharp, burr-free tip (for minimal patient discomfort) and a polished inner surface (for consistent fluid flow). Their previous supplier used conventional turning, which caused 5% of needles to fail (uneven tips, inconsistent inner diameter) and had a 3-week lead time.​

• Solution: Nous avons utilisé CNC Suisse with a 12mm-capacity Swiss machine, carbide turning tools, and micro-grinding tools for the needle tip. We optimized the process with automatic bar feeders (3-meter bars) for unattended operation and in-line vision systems to inspect tip sharpness and inner diameter in real time. For the polished inner surface, we used a diamond-coated honing tool in the live tooling turret. We ran 10 machines 24/7 to meet high-volume demand.​

• Résultats:​

• Le taux de défaut a chuté de 5% to 0.3%—only 3,000 needles failed per month (contre. 50,000 previously).​

• Lead time shortened from 3 des semaines pour 10 days—helping the client keep up with global demand for medical supplies.​

• The client’s customer satisfaction score increased by 20% (due to smoother needle insertion and consistent performance).​

Étude de cas 2: Electronics Manufacturer (Brass PCB Pins)​

• Défi: Le client avait besoin 200,000 brass PCB pins monthly (1diamètre mm, 10longueur mm, ±0.002mm tolerance) for smartphones. Each pin required a 0.5mm cross-hole (for wiring) and a gold-plated finish. The client needed a 2-week lead time to support their smartphone assembly line. Their previous supplier used stamping, which caused 8% of pins to have misaligned cross-holes.​

• Solution: Nous avons utilisé CNC Suisse with live tooling (0.5mm carbide drills) to machine the cross-hole in-line with turning. We used a gang tool post for fast tool changes and automatic bar feeders for unattended operation. Après l'usinage, Nous avons ajouté électroplaste (or, 5µm d'épaisseur) et conduit 100% inspection with laser micrometers (to verify diameter) et comparateurs optiques (to check cross-hole alignment).​

• Résultats:​

• Cross-hole misalignment dropped from 8% to 0.2%—only 400 pins failed per month (contre. 16,000 previously).​

• Lead time was met (2 semaines)—ensuring the client’s assembly line stayed on schedule.​

• Production cost per pin decreased by 25% (reduced rework and eliminated secondary operations for cross-holes).​

• Challenge Overcome: Stamping couldn’t achieve precise cross-hole alignment for small pins; CNC Swissing’s live tooling and guide bushing support solved this issue.​

Témoignage client: “The PCB pins fit perfectly into our smartphones—no more assembly delays from misaligned holes. The gold plating is consistent, and the lead time is reliable. We now source all our small electronics pins from them.” — Robert T., Electronics Component Manager.
