What Is CNC Broaching?
CNC -Formen ist ein spezialisiertes Schnittprozess in machining that uses a toothed tool called a Broaching Tool to remove material from a workpiece, präzise erstellen, Komplexe Formen (such as keyways, splines, Getriebe, or slots) in a single pass. Unlike manual broaching, CNC (Computer numerische Steuerung) broaching uses computer programs to control the tool’s movement, Gewährleistung einer beispiellosen Genauigkeit und Wiederholbarkeit.
Im Kern, Die Konzept of CNC Broaching revolves around efficiency: instead of multiple setup changes for different cuts, Die Broaching Tool (which has teeth increasing in size) completes the entire cut in one operation. This makes it ideal for high-volume production while maintaining strict quality standards.

| CNC Broaching | Computer-controlled broaching process | Automates tool movement for precision and consistency |
| Broaching Tool | Toothed cutting tool with progressively sized teeth | Removes material to create desired shapes in one pass |

Verfahren: How CNC Broaching Works
Der CNC Broaching Process is streamlined and efficient, mit klar Schritte that minimize setup time and maximize accuracy. Unlike other machining methods (Z.B., milling or turning), broaching relies on a linear tool path to create complex shapes in one go.
Step-by-Step CNC Broaching Operation Procedure
- Maschinenaufbau: The workpiece is clamped securely in a fixture, and the CNC program (which defines the Werkzeugweg und Schneidenparameter) is loaded into the machine. Our technicians calibrate the machine to ensure alignment with the workpiece’s reference points.
- Werkzeugvorbereitung: The appropriate Broaching Tool (selected based on material, Teilgeometrie, and tolerance requirements) is mounted onto the machine’s spindle. Tools are inspected for sharpness and wear before each run.
- Cutting Sequence: The CNC machine moves the Broaching Tool linearly across (or into) das Werkstück. Each tooth on the tool removes a small amount of material—starting with the smallest tooth and ending with the largest, which achieves the final shape.
- Qualitätsprüfung: After the cut is complete, the workpiece is removed and inspected for dimensional accuracy and surface finish using precision measuring tools (Z.B., Mikrometer, Cmm).
- Part Ejection & Next Cycle: The finished part is ejected, and the machine resets for the next workpiece—all automated to reduce downtime.
The entire process typically takes 30 Sekunden bis 2 Minuten pro Teil, depending on the complexity—making it far faster than multi-step machining methods.
Materialien: What Can We Broach?
CNC Broaching works with a wide range of materials, from soft plastics to hard alloys. The choice of material depends on the part’s end-use (Z.B., strength for automotive parts, corrosion resistance for medical devices) and determines the Broaching Tool type and cutting parameters.
Common Materials for CNC Broaching
| Materialtyp | Beispiele | Schlüsseleigenschaften | Ideale Anwendungen |
| Metalle | Stahl (leicht, Legierung, rostfrei), Aluminium | Stahl: Hohe Stärke; Aluminium: Leicht, Gute thermische Leitfähigkeit | Stahl: Zahnradwellen, Bauhalterungen; Aluminium: Elektronikgehäuse, Kfz -Trim |
| Legierungen | Titanlegierung, Brass alloy, Copper alloy | Titan: Hochfestes Verhältnis; Messing: Korrosionsbeständig, gute maschinabilität | Titan: Luft- und Raumfahrtkomponenten; Messing: Sanitärarmaturen, elektrische Anschlüsse |
| Plastik | Nylon, SPÄHEN, Acetal | Leicht, korrosionsbeständig, geringe Reibung | Komponenten für medizinische Geräte, Teile der Unterhaltungselektronik |
We test each material with sample cuts to optimize the Schnittprozess—ensuring minimal tool wear and maximum part quality. Zum Beispiel, when broaching stainless steel (ein hartes Material), we use carbide Broaching Tools and slower cutting speeds to maintain precision.
Oberflächenbehandlung: Verbesserung der Teilleistung
After CNC Broaching, Oberflächenbehandlung (oder fertig) is often applied to improve the part’s durability, Aussehen, oder Funktionalität. The right treatment depends on the material and the part’s end-use (Z.B., Wärmebehandlung für Festigkeit, plating for corrosion resistance).
Our Surface Treatment Options
| Behandlungstyp | Prozess | Vorteile | Typische Anwendungsfälle |
| Wärmebehandlung | Heating and cooling the part to alter its microstructure (Z.B., Glühen, Quenching) | Erhöht die Härte, Stärke, and wear resistance | Kfz -Zahnräder, machinery shafts |
| Überzug | Depositing a thin layer of metal (Z.B., Chrom, Nickel, Zink) onto the part’s surface | Verbessert die Korrosionsresistenz, Leitfähigkeit, and appearance | Elektrische Anschlüsse, Meereskomponenten |
| Beschichtung | Applying a protective layer (Z.B., Keramik, Ptfe) | Reduziert die Reibung, enhances chemical resistance | Medizinprodukte, Industrieventile |
| Malerei | Applying a decorative or protective paint layer | Improves aesthetics and prevents rust | Consumer-facing parts (Z.B., Gerätegriffe) |
We work with trusted surface treatment partners to ensure consistency—for example, our zinc-plated parts meet ASTM B633 standards, providing up to 1,000 hours of corrosion resistance in salt spray tests.
Toleranzen: The Precision We Deliver
Toleranzen are critical in CNC Broaching—even small deviations can affect a part’s performance (Z.B., a loose keyway in a gear shaft can cause machinery failure). Our process is optimized to achieve tight dimensional tolerance und glatt Oberflächenrauheit, meeting or exceeding industry standards.
Unsere Toleranzfähigkeiten vs. Industrie -Durchschnittswerte
| Metrik | Unsere Fähigkeit | Branchendurchschnitt | Vorteil |
| Dimensionstoleranz | ± 0,0005 ” (0.0127 mm) | ±0.0015” (0.0381 mm) | 3x tighter tolerance for high-precision parts |
| Oberflächenrauheit (Ra) | 0.8 – 3.2 μm | 3.2 – 6.3 μm | Smoother surface for reduced friction and improved aesthetics |
| Positional Tolerance | ± 0,001 ” (0.0254 mm) | ±0.003” (0.0762 mm) | More accurate part alignment for assembly |
Um diese Toleranzen aufrechtzuerhalten, we use CNC machines with linear encoders (Genauigkeit: ±0.0001” per foot) and perform in-process inspections every 20 Teile. This ensures Konsistenz across even large production runs.
Vorteile: Why Choose CNC Broaching Over Other Methods?
CNC Broaching offers unique Vorteile that make it superior to traditional machining methods (Z.B., Mahlen, Gestaltung) for many applications. Its combination of efficiency, Präzision, and cost-effectiveness makes it a top choice for manufacturers.

| Time-Saving | Schnelle Zykluszeiten (30 sec–2 min per part) and minimal downtime | Meets tight deadlines for urgent orders |
| Komplexe Formfähigkeit | Creates intricate shapes (Z.B., internal splines, blind keyways) that are hard to achieve with other methods | Eliminates the need for secondary operations (Z.B., Schleifen) |
Zum Beispiel, a client producing automotive transmission shafts switched from milling to our CNC Broaching service and cut their production time from 10 minutes per part to 90 seconds—while reducing scrap from 4% Zu 0.5%.
