What Is CNC Broaching?
Brocciatura CNC è specializzato processo di taglio in machining that uses a toothed tool called a Broaching Tool to remove material from a workpiece, Creare preciso, forme complesse (such as keyways, splines, marcia, or slots) in a single pass. Unlike manual broaching, CNC (Controllo numerico del computer) broaching uses computer programs to control the tool’s movement, Garantire precisione e ripetibilità senza pari.
Al centro, IL concetto of CNC Broaching revolves around efficiency: instead of multiple setup changes for different cuts, IL 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.

Processo: How CNC Broaching Works
IL CNC Broaching Process is streamlined and efficient, con chiaro Passi that minimize setup time and maximize accuracy. Unlike other machining methods (PER ESEMPIO., milling or turning), broaching relies on a linear tool path to create complex shapes in one go.
Step-by-Step CNC Broaching Operation Procedure
- Configurazione della macchina: The workpiece is clamped securely in a fixture, and the CNC program (which defines the tool path e tagliare i parametri) is loaded into the machine. Our technicians calibrate the machine to ensure alignment with the workpiece’s reference points.
- Preparazione degli strumenti: The appropriate Broaching Tool (selected based on material, geometria in parte, 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) il pezzo. 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.
- Controllo di qualità: After the cut is complete, the workpiece is removed and inspected for dimensional accuracy and surface finish using precision measuring tools (PER ESEMPIO., micrometri, CMMS).
- 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 secondi a 2 minuti per parte, depending on the complexity—making it far faster than multi-step machining methods.
Materiali: 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 (PER ESEMPIO., strength for automotive parts, corrosion resistance for medical devices) and determines the Broaching Tool type and cutting parameters.
Common Materials for CNC Broaching
| Tipo di materiale | Esempi | Proprietà chiave | Applicazioni ideali |
| Metalli | Acciaio (blando, lega, inossidabile), Alluminio | Acciaio: Alta resistenza; Alluminio: Leggero, Buona conduttività termica | Acciaio: Alberi di ingranaggio, parentesi di costruzione; Alluminio: Recinti elettronici, rivestimento automobilistico |
| Leghe | Lega di titanio, Brass alloy, Copper alloy | Titanio: Rapporto elevato di forza-peso; Ottone: Resistente alla corrosione, Buona macchinabilità | Titanio: Componenti aerospaziali; Ottone: Raccordi idraulici, Connettori elettrici |
| Plastica | Nylon, SBIRCIARE, Acetal | Leggero, resistente alla corrosione, basso attrito | Componenti del dispositivo medico, Parti di elettronica di consumo |
We test each material with sample cuts to optimize the processo di taglio—ensuring minimal tool wear and maximum part quality. Per esempio, when broaching stainless steel (un materiale duro), we use carbide Broaching Tools and slower cutting speeds to maintain precision.
Trattamento superficiale: Migliorare le prestazioni della parte
After CNC Broaching, Trattamento superficiale (O finitura) is often applied to improve the part’s durability, aspetto, o funzionalità. The right treatment depends on the material and the part’s end-use (PER ESEMPIO., heat treatment for strength, plating for corrosion resistance).
Our Surface Treatment Options
| Treatment Type | Processo | Benefici | Casi d'uso tipici |
| Trattamento termico | Heating and cooling the part to alter its microstructure (PER ESEMPIO., ricottura, spegnimento) | Aumenta la durezza, forza, and wear resistance | Ingranaggi automobilistici, machinery shafts |
| Placcatura | Depositing a thin layer of metal (PER ESEMPIO., cromo, nichel, zinco) onto the part’s surface | Migliora la resistenza alla corrosione, conduttività, and appearance | Connettori elettrici, componenti marini |
| Rivestimento | Applying a protective layer (PER ESEMPIO., ceramica, Ptfe) | Riduce l'attrito, enhances chemical resistance | Dispositivi medici, valvole industriali |
| Pittura | Applying a decorative or protective paint layer | Improves aesthetics and prevents rust | Consumer-facing parts (PER ESEMPIO., 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.
Tolleranze: The Precision We Deliver
Tolleranze are critical in CNC Broaching—even small deviations can affect a part’s performance (PER ESEMPIO., a loose keyway in a gear shaft can cause machinery failure). Our process is optimized to achieve tight dimensional tolerance and smooth Rugosità superficiale, meeting or exceeding industry standards.
Le nostre capacità di tolleranza vs. Medie del settore
| Metrica | La nostra capacità | Media del settore | Vantaggio |
| Tolleranza dimensionale | ± 0,0005 " (0.0127 mm) | ±0.0015” (0.0381 mm) | 3x tighter tolerance for high-precision parts |
| Rugosità superficiale (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 |
Per mantenere queste tolleranze, we use CNC machines with linear encoders (precisione: ±0.0001” per foot) and perform in-process inspections every 20 parti. This ensures coerenza across even large production runs.
Vantaggi: Why Choose CNC Broaching Over Other Methods?
CNC Broaching offers unique benefici that make it superior to traditional machining methods (PER ESEMPIO., fresatura, modellando) for many applications. Its combination of efficiency, precisione, and cost-effectiveness makes it a top choice for manufacturers.
