What Is CNC Broaching?
Brochante de CNC es un especializado proceso de corte in machining that uses a toothed tool called a Broaching Tool to remove material from a workpiece, creando precisos, formas complejas (such as keyways, splines, engranaje, or slots) in a single pass. Unlike manual broaching, CNC (Control numérico de la computadora) broaching uses computer programs to control the tool’s movement, garantizar una precisión incomparable y repetibilidad.
En su núcleo, el concepto of CNC Broaching revolves around efficiency: instead of multiple setup changes for different cuts, el 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.
| Término clave | Meaning | Role in CNC Broaching |

| Broaching Tool | Toothed cutting tool with progressively sized teeth | Removes material to create desired shapes in one pass |

Proceso: How CNC Broaching Works
El CNC Broaching Process is streamlined and efficient, con claro pasos that minimize setup time and maximize accuracy. Unlike other machining methods (P.EJ., milling or turning), broaching relies on a linear tool path to create complex shapes in one go.
Step-by-Step CNC Broaching Operation Procedure
- Configuración de la máquina: The workpiece is clamped securely in a fixture, and the CNC program (which defines the ruta de la herramienta y parámetros de corte) is loaded into the machine. Our technicians calibrate the machine to ensure alignment with the workpiece’s reference points.
- Preparación de herramientas: The appropriate Broaching Tool (selected based on material, Parte de geometría, 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 pieza de trabajo. 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.
- Cheque de calidad: After the cut is complete, the workpiece is removed and inspected for dimensional accuracy and surface finish using precision measuring tools (P.EJ., micrómetros, CMMS).
- Expulsión de piezas & 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 segundos a 2 minutos por parte, depending on the complexity—making it far faster than multi-step machining methods.
Materiales: 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 (P.EJ., strength for automotive parts, corrosion resistance for medical devices) and determines the Broaching Tool type and cutting parameters.
Common Materials for CNC Broaching
| Tipo de material | Ejemplos | Propiedades clave | Aplicaciones ideales |
| Rieles | Acero (leve, aleación, inoxidable), Aluminio | Acero: Alta fuerza; Aluminio: Ligero, buena conductividad térmica | Acero: Ejes de engranajes, soporte de construcción; Aluminio: Gabinetes electrónicos, adorno automotriz |
| Aleaciones | Aleación de titanio, Brass alloy, Copper alloy | Titanio: Alta relación resistencia a peso; Latón: Resistente a la corrosión, buena maquinabilidad | Titanio: Componentes aeroespaciales; Latón: Accesorios de fontanería, conectores eléctricos |
| Plástico | Nylon, OJEADA, Acetal | Ligero, resistente a la corrosión, baja fricción | Componentes del dispositivo médico, Piezas electrónicas de consumo |
We test each material with sample cuts to optimize the proceso de corte—ensuring minimal tool wear and maximum part quality. Por ejemplo, when broaching stainless steel (un material duro), we use carbide Broaching Tools and slower cutting speeds to maintain precision.
Tratamiento superficial: Mejorar el rendimiento de la parte
After CNC Broaching, tratamiento superficial (o refinamiento) is often applied to improve the part’s durability, apariencia, o funcionalidad. The right treatment depends on the material and the part’s end-use (P.EJ., heat treatment for strength, plating for corrosion resistance).
Our Surface Treatment Options
| Tipo de tratamiento | Proceso | Beneficio | Casos de uso típicos |
| Tratamiento térmico | Heating and cooling the part to alter its microstructure (P.EJ., recocido, temple) | Aumenta la dureza, fortaleza, and wear resistance | Engranajes automotrices, machinery shafts |
| Enchapado | Depositing a thin layer of metal (P.EJ., cromo, níquel, zinc) onto the part’s surface | Mejora la resistencia a la corrosión, conductividad, and appearance | Conectores eléctricos, componentes marinos |
| Revestimiento | Applying a protective layer (P.EJ., cerámico, Ptfe) | Reduce la fricción, enhances chemical resistance | Dispositivos médicos, válvulas industriales |
| Cuadro | Applying a decorative or protective paint layer | Improves aesthetics and prevents rust | Consumer-facing parts (P.EJ., 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.
Tolerancias: The Precision We Deliver
Tolerancias are critical in CNC Broaching—even small deviations can affect a part’s performance (P.EJ., a loose keyway in a gear shaft can cause machinery failure). Our process is optimized to achieve tight dimensional tolerance and smooth aspereza de la superficie, meeting or exceeding industry standards.
Nuestras capacidades de tolerancia vs. Promedios de la industria
| Métrico | Nuestra capacidad | Promedio de la industria | Ventaja |
| Tolerancia dimensional | ± 0.0005 " (0.0127 milímetros) | ±0.0015” (0.0381 milímetros) | 3x tighter tolerance for high-precision parts |
| Aspereza de la superficie (Real academia de bellas artes) | 0.8 – 3.2 μm | 3.2 – 6.3 μm | Smoother surface for reduced friction and improved aesthetics |
| Positional Tolerance | ± 0.001 " (0.0254 milímetros) | ±0.003” (0.0762 milímetros) | More accurate part alignment for assembly |
Para mantener estas tolerancias, we use CNC machines with linear encoders (exactitud: ±0.0001” per foot) and perform in-process inspections every 20 regiones. This ensures consistencia across even large production runs.
Ventajas: Why Choose CNC Broaching Over Other Methods?
