What Is CNC Broaching?
Brochage CNC est un spécialisé processus de coupe in machining that uses a toothed tool called a Broaching Tool to remove material from a workpiece, Créer un précis, formes complexes (such as keyways, splines, engrenages, or slots) in a single pass. Unlike manual broaching, CNC (Contrôle numérique de l'ordinateur) broaching uses computer programs to control the tool’s movement, assurer une précision et une répétabilité inégalées.
À la base, le concept of CNC Broaching revolves around efficiency: instead of multiple setup changes for different cuts, le 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.

Processus: How CNC Broaching Works
Le CNC Broaching Process is streamlined and efficient, avec clair mesures that minimize setup time and maximize accuracy. Unlike other machining methods (Par exemple, milling or turning), broaching relies on a linear tool path to create complex shapes in one go.
Step-by-Step CNC Broaching Operation Procedure
- Configuration de la machine: The workpiece is clamped securely in a fixture, and the CNC program (which defines the trajectoire d'outil et des paramètres de coupe) is loaded into the machine. Our technicians calibrate the machine to ensure alignment with the workpiece’s reference points.
- Préparation des outils: The appropriate Broaching Tool (selected based on material, géométrie en partie, 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) la pièce. 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.
- Chèque de qualité: After the cut is complete, the workpiece is removed and inspected for dimensional accuracy and surface finish using precision measuring tools (Par exemple, micromètres, CMMS).
- Éjection de pièce & 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 quelques secondes à 2 minutes par partie, depending on the complexity—making it far faster than multi-step machining methods.
Matériels: 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 (Par exemple, strength for automotive parts, corrosion resistance for medical devices) and determines the Broaching Tool type and cutting parameters.
Common Materials for CNC Broaching
| Type de matériau | Exemples | Propriétés clés | Applications idéales |
| Métaux | Acier (bénin, alliage, inoxydable), Aluminium | Acier: Forte résistance; Aluminium: Léger, bonne conductivité thermique | Acier: Arbres de vitesses, supports de construction; Aluminium: Enclos électronique, garniture automobile |
| Alliages | Alliage en titane, Brass alloy, Copper alloy | Titane: Ratio de force / poids élevé; Laiton: Résistant à la corrosion, bonne machinabilité | Titane: Composants aérospatiaux; Laiton: Raccords de plomberie, connecteurs électriques |
| Plastique | Nylon, Jeter un coup d'œil, Acetal | Léger, résistant à la corrosion, frottement faible | Composants de dispositifs médicaux, pièces électroniques grand public |
We test each material with sample cuts to optimize the processus de coupe—ensuring minimal tool wear and maximum part quality. Par exemple, when broaching stainless steel (Un matériau dur), we use carbide Broaching Tools and slower cutting speeds to maintain precision.
Traitement de surface: Améliorer les performances de la pièce
After CNC Broaching, traitement de surface (ou finition) is often applied to improve the part’s durability, apparence, ou fonctionnalité. The right treatment depends on the material and the part’s end-use (Par exemple, Traitement thermique pour la résistance, plating for corrosion resistance).
Our Surface Treatment Options
| Type de traitement | Procéder | Avantages | Cas d'utilisation typiques |
| Traitement thermique | Heating and cooling the part to alter its microstructure (Par exemple, recuit, éteinte) | Augmente la dureté, force, and wear resistance | Engrenages automobiles, machinery shafts |
| Placage | Depositing a thin layer of metal (Par exemple, chrome, nickel, zinc) onto the part’s surface | Améliore la résistance à la corrosion, conductivité, and appearance | Connecteurs électriques, composants marins |
| Revêtement | Applying a protective layer (Par exemple, céramique, Ptfe) | Réduit la friction, enhances chemical resistance | Dispositifs médicaux, vannes industrielles |
| Peinture | Applying a decorative or protective paint layer | Improves aesthetics and prevents rust | Consumer-facing parts (Par exemple, appliance handles) |
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.
Tolérances: The Precision We Deliver
Tolérances are critical in CNC Broaching—even small deviations can affect a part’s performance (Par exemple, a loose keyway in a gear shaft can cause machinery failure). Our process is optimized to achieve tight dimensional tolerance and smooth rugosité de surface, meeting or exceeding industry standards.
Nos capacités de tolérance vs. Moyennes de l'industrie
| Métrique | Notre capacité | Moyenne de l'industrie | Avantage |
| Tolérance dimensionnelle | ± 0,0005 ” (0.0127 MM) | ±0.0015” (0.0381 MM) | 3x tighter tolerance for high-precision parts |
| Rugosité de surface (Rampe) | 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 |
Pour maintenir ces tolérances, we use CNC machines with linear encoders (précision: ±0.0001” per foot) and perform in-process inspections every 20 parties. This ensures cohérence across even large production runs.
Avantages: Why Choose CNC Broaching Over Other Methods?
CNC Broaching offers unique avantages that make it superior to traditional machining methods (Par exemple, fraisage, mise en forme) for many applications. Its combination of efficiency, précision, and cost-effectiveness makes it a top choice for manufacturers.

| Time-Saving | Temps de cycle rapide (30 sec–2 min per part) and minimal downtime | Meets tight deadlines for urgent orders |
| Capacité de forme complexe | Creates intricate shapes (Par exemple, internal splines, blind keyways) that are hard to achieve with other methods | Eliminates the need for secondary operations (Par exemple, affûtage) |
Par exemple, 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% à 0.5%.
