What Is CNC Swissing?

CNC -Schweiß- auch bekannt als Schweizer Schraubbearbeitung oder 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.​

Der Prozessübersicht revolves around a unique design: Unlike conventional turning (where the workpiece is held at one end), CNC Swissing uses a Führungsbuchse—a precision sleeve that supports the workpiece close to the cutting tool. This minimizes vibration and deflection, even for long, dünne Teile (Z.B., medical needles, electronics pins).​

To explain “Wie es funktioniert” simply: The workpiece is fed through the guide bushing and rotated by a spindle. Schneidwerkzeuge (mounted on a sliding turret or gang tool post) move along multiple axes (X, Y, 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.​

Zusamenfassend, CNC Swissing is the go-to for “micro-precision” parts: If a component is small (typically ≤25mm diameter), lang (length-to-diameter ratio ≥10:1), or requires complex features (Z.B., multiple threads, Slots, cross-holes), CNC Swissing delivers results conventional machining can’t match.

Ob du brauchst 100 titanium medical needles (0.8mm Durchmesser) oder 500,000 brass electronics pins (2mm Durchmesser), our CNC Swissing capabilities scale to match your project’s complexity and volume.

The CNC Swissing Process

Unser Schritt-für-Schritt-Prozess is optimized to leverage the unique advantages of Schweizer Schraubbearbeitung—minimizing vibration, maximizing precision, and streamlining production:​

1. Design and CAD Modeling: We start by reviewing your CAD model (or creating one from sketches/specifications). 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, we use 3D simulation to test feasibility.​

2. Cam -Programmierung: The CAD model is imported into CAM software (Mastercam Swiss, Gibbscam) to generate optimized Werkzeugpfade. We program sequential operations (turning → drilling → tapping → milling) and synchronize tool movements with spindle rotation. Für hochvolumige Läufe, we add in-line inspection triggers (Z.B., check diameter after turning).​

3. Setup and Calibration: The workpiece (usually a bar stock) is loaded into the machine’s spindle and fed through the Führungsbuchse (calibrated to within ±0.0005mm of the spindle axis). Cutting tools are mounted on the turret/gang tool post, Und coolant systems are activated. We run a test part to verify tolerances and adjust tool offsets if needed.​

4. Bearbeitungsausführung: The machine runs the CAM program, with the guide bushing supporting the workpiece during cutting. Live tooling adds complex features (Z.B., cross-holes, Themen) ohne den Teil neu positionieren. Our operators monitor the process via CNC software, adjusting spindle speed/feed rate for material-specific needs (Z.B., slower speeds for titanium).​

5. Post-Machining Inspection: Parts undergo rigorous Qualitätskontrolle—100% inspection for critical components (Z.B., Medizinprodukte) using CMMs and optical comparators. We verify dimensions, Toleranzen, and surface finish against CAD data. Für hochvolumige Läufe, in-line vision systems flag defects in real time.​

Swiss Screw Machine Operation Review: Nach der Produktion, 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 -Schweiß offers unique benefits for small, Komplexe Teile:​

1. Hohe Präzision: With tolerances as tight as ±0.0005mm, it produces parts that fit seamlessly—critical for micro-medical components (Z.B., Katheterspitzen) or electronics pins where even tiny gaps cause failure.​

2. Consistency and Repeatability: The guide bushing minimizes vibration, and CNC automation ensures every part is identical—even for high-volume orders (Z.B., 500,000 brass terminals).​

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

4. Reduzierte Setup -Zeit: 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: Hochgeschwindigkeitsbearbeitung (bis zu 15,000 RPM for aluminum) and unattended operation reduce per-part cycle time. Für Großserienteile, we achieve production rates of 10–50 parts per minute.​

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

7. Kosteneffizienz: While upfront costs are higher than conventional machining, reduced secondary operations, minimaler Abfall (Präzisionsabschneiden), and fast cycle times lower long-term costs—especially for high-volume orders.​

8. Enge Toleranzen: The guide bushing’s support is unmatched for long, dünne Teile (Z.B., 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.

Branchenanwendungen

CNC -Schweiß is indispensable across industries that rely on small, Hochvorbereitete Komponenten. Hier sind die häufigsten Anwendungen:

Zum Beispiel, in the medical industry, our CNC-swissed hypodermic needles (0.8mm Durchmesser, ±0.001mm tolerance) ensure consistent fluid flow and minimal patient discomfort. In Elektronik, our brass PCB pins (1mm Durchmesser) 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 Bearbeitungstechniken and optimize processes for small, Komplexe Teile:​

• Swiss Turning with Live Tooling:​

• The core technique of CNC Swissing—combines conventional turning (shaping outer diameters) mit Live -Werkzeug (Übungen, Taps, mills mounted on the turret). This lets us add cross-holes, Themen, or slots in one setup—eliminating secondary operations. Zum Beispiel, we can machine an electronics pin with a threaded end, a cross-hole for wiring, and a knurled section in a single cycle.​

• Wir verwenden gang tooling (multiple tools mounted side-by-side) für einfache Teile (Z.B., straight pins) to reduce tool change time, Und turret tooling (rotating tool post) für komplexe Teile (Z.B., medical screws with multiple features).​

• Micro-Machining for Tiny Parts:​

• For components ≤1mm diameter (Z.B., micro-needles), Wir verwenden micro-live tooling (0.1mm-diameter drills/mills) und extrem niedrige Vorschubgeschwindigkeiten (5–10 mm/min) to avoid tool breakage. We also use air-cooled spindles (instead of coolant) for micro-parts to prevent residue buildup on small features.​

• Bar Feeding and Unattended Operation:​

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

• Werkzeugpfadoptimierung:​

• CAM software generates Werkzeugpfade that minimize tool travel and prioritize features by accessibility. Zum Beispiel, we machine outer diameters first (to stabilize the part), then add inner features (Z.B., Löcher) and finally complex features (Z.B., unterkuppelt). For exotic metals like inconel, Wir verwenden trochoidal turning (a circular tool path) to distribute cutting force evenly and extend tool life.​

• Cutting Tool Selection:​

• Carbid -Werkzeuge: Für die meisten Metalle (Stahl, Aluminium, Messing)—durable and cost-effective for high-volume runs. We use coated carbide (Tialn) for heat resistance.​

• Diamond-Coated Tools: Für Nichtmetalle (SPÄHEN, Acryl) and exotic metals—prevent chipping and ensure smooth surface finishes.​

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

• Kühlmittelsysteme:​

• 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) und Material. For soft metals (Kupfer), we use carbide bushings to prevent wear; for hard metals (Titan), we use diamond-coated bushings for longer life. We also lubricate bushings with high-pressure oil to reduce friction between the part and bushing.

Fallstudien: CNC Swissing Success Stories

Unser CNC Swissing services have solved complex small-component challenges for clients across medical, Elektronik, und Luft- und Raumfahrtindustrie. Unten sind zwei Erfolgreiche Projekte showcasing our expertise in micro-precision and high-volume production:​

Fallstudie 1: Medical Device Company (Stainless Steel Hypodermic Needles)​

• Herausforderung: Der Kunde benötigte 1,000,000 stainless steel hypodermic needles monthly (0.8mm Außendurchmesser, 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.​

• Lösung: Wir haben benutzt CNC -Schweiß 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 Maschinen 24/7 to meet high-volume demand.​

• Ergebnisse:​

• Die Defektrate fiel von gesunken 5% to 0.3%—only 3,000 needles failed per month (vs. 50,000 previously).​

• Lead time shortened from 3 Wochen zu 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).​

• Client -Zeugnis: “CNC Swissing transformed our needle production. The precision and speed are unmatched, and the defect reduction saved us thousands in rework costs. We’ve expanded our order to include other medical components.” — Jennifer M., Medical Device Production Director.​

Fallstudie 2: Electronics Manufacturer (Brass PCB Pins)​

• Herausforderung: Der Kunde benötigte 200,000 brass PCB pins monthly (1mm Durchmesser, 10MM Länge, ±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.​

• Lösung: Wir haben benutzt CNC -Schweiß 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. Nach der Bearbeitung, Wir haben hinzugefügt elektroplierend (Gold, 5µm Dicke) und durchgeführt 100% inspection with laser micrometers (to verify diameter) und optische Komparatoren (to check cross-hole alignment).​

• Ergebnisse:​

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

• Lead time was met (2 Wochen)—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.​

Client -Zeugnis: “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.
