What Is CNC Boring?
Mandrinado CNC es un especializado proceso de mecanizado that uses a rotating cutting tool called a Boring Tool to enlarge existing holes, refine their internal diameter, or create precise internal shapes (such as stepped holes, cirios, or grooves) in a workpiece. Unlike manual boring, CNC (Control numérico por computadora) boring uses pre-programmed computer instructions to control the Boring Tool’s movement, ensuring exceptional precisión and repeatability in every operation.
el núcleo concepto of CNC Boring lies in its ability to achieve tight tolerances on internal features that are hard to reach with other machining methods. Instead of relying on manual adjustment, the computer-controlled system maintains consistent cutting parameters, making it ideal for both small-batch prototypes and large-volume production runs.

Proceso: How CNC Boring Works
El CNC Boring Process es un simplificado, step-by-step workflow designed to minimize errors and maximize efficiency. Unlike some machining methods that require multiple setups, CNC Boring uses precise programming to complete most internal machining tasks in a single operation.
Step-by-Step CNC Boring Operation Procedure
- Configuración de la máquina: The workpiece is securely clamped in a fixture (p.ej., a vise or chuck) para evitar el movimiento durante el mecanizado. Our technicians load the CNC program— which defines the tool path, velocidad de corte, tasa de avance, and depth of cut—into the machine’s control system. The machine is then calibrated to align with the workpiece’s reference points (p.ej., existing holes or part edges).
- Tool Preparation: el apropiado Boring Tool (selected based on workpiece material, hole size, and tolerance requirements) is mounted onto the machine’s spindle. Tools are inspected for sharpness, tener puesto, and proper alignment before each run to ensure consistent results.
- Cutting Sequence: The CNC machine moves the rotating Boring Tool into the workpiece’s existing hole (or starting point). The tool follows the pre-programmed tool path to remove material—either enlarging the hole to the desired diameter, refining its surface, or creating complex internal shapes (p.ej., steps or tapers). For deep holes, the tool may pause periodically to clear chips and prevent overheating.
- Quality Check: After the boring operation is complete, the workpiece is removed from the fixture and inspected using precision measuring tools (p.ej., bore gauges, máquinas de medición de coordenadas (CMM), and surface roughness testers). This ensures the hole meets the specified tolerancias and surface finish.
- Part Ejection & Next Cycle: The finished part is ejected, and the machine resets—either for the next workpiece (in high-volume production) or for reconfiguration (for custom parts). The automated reset process reduces downtime and keeps production on track.
The entire process typically takes 45 segundos para 3 minutos por parte, depending on the hole depth, complejidad, and material—making it significantly faster than manual boring or less precise machining methods.
Materiales: What Can We Bore?
CNC Boring is compatible with a wide range of Boring Materials, from soft plastics to hard metals and alloys. The choice of material depends on the part’s end-use (p.ej., strength for structural components, corrosion resistance for medical devices) and directly influences the selection of Boring Tool and cutting parameters.
Common Materials for CNC Boring
| Tipo de material | Ejemplos | Propiedades clave | Aplicaciones ideales |
| Rieles | Acero (mild, aleación, stainless), Aluminio, Cobre | Acero: High strength and durability; Aluminio: Lightweight and corrosion-resistant; Cobre: Excellent thermal and electrical conductivity | Acero: Automotive engine blocks, construction machinery parts; Aluminio: Aerospace structural components, electronics heat sinks; Cobre: Conectores electricos, intercambiadores de calor |
| Alloys | Titanium alloy, Brass alloy, Inconel (nickel-chromium alloy) | Titanium alloy: High strength-to-weight ratio and biocompatibility; Brass alloy: Machinability and corrosion resistance; Inconel: Heat resistance and durability in extreme environments | Titanium alloy: Implantes medicos, aerospace turbine parts; Brass alloy: Accesorios de fontanería, instrumentos musicales; Inconel: Componentes del motor a reacción, industrial furnaces |
| Plástico | Nylon, OJEADA (polyether ether ketone), Acetal | Nylon: Impact resistance and low friction; OJEADA: High temperature resistance and biocompatibility; Acetal: Dimensional stability and wear resistance | Nylon: Cajas de engranajes, piezas de electrodomésticos; OJEADA: Componentes de dispositivos médicos, aerospace interiors; Acetal: Consumer electronics casings, engranajes de precisión |
Before starting production, we conduct test runs on each material to optimize the proceso de mecanizado. Por ejemplo, when boring hard materials like stainless steel or Inconel, we use carbide-tipped Boring Tools and slower feed rates to maintain precision and prevent tool wear. For soft materials like aluminum or plastic, we use high-speed steel (HSS) tools and faster feed rates to avoid material deformation.
Tratamiento superficial: Mejora del rendimiento de las piezas
After CNC Boring, tratamiento superficial (o refinamiento) is often applied to improve the part’s functionality, durabilidad, o apariencia. The right treatment depends on the material, the part’s end-use, and your specific requirements (p.ej., resistencia a la corrosión, resistencia al desgaste, or aesthetic appeal).
Our Surface Treatment Options
| Tipo de tratamiento | Proceso | Beneficios | Casos de uso típicos |
| Tratamiento térmico | Heating the workpiece to a specific temperature, holding it, then cooling it at a controlled rate (p.ej., recocido, hardening, tempering) | Aumenta la dureza, fortaleza, y resistencia al desgaste; reduces internal stress | Automotive transmission components, machinery shafts, construction tool parts |
| Enchapado | Depositing a thin layer of metal (p.ej., cromo, níquel, zinc) onto the part’s surface using electrochemical processes | Mejora la resistencia a la corrosión, conductividad, y estética; adds a protective barrier | Conectores electricos (niquelado), componentes marinos (galvanizado), piezas decorativas (cromado) |
| Revestimiento | Applying a thin, protective layer (p.ej., revestimiento cerámico, PTFE (teflón) revestimiento, recubrimiento en polvo) to the part’s surface | Reduces friction, enhances chemical resistance, and improves heat resistance | Dispositivos médicos (biocompatible ceramic coating), válvulas industriales (Recubrimiento de PTFE), outdoor machinery parts (recubrimiento en polvo) |
| Cuadro | Applying a decorative or protective paint layer (p.ej., esmalte, acrílico) to the part’s surface | Mejora la estética, prevents rust, and adds a barrier against environmental damage | Consumer-facing appliances, outdoor construction equipment, decorative machinery parts |
We partner with trusted tratamiento superficial specialists to ensure consistency and quality. Por ejemplo, our zinc-plated bored parts meet ASTM B633 standards, providing up to 1,200 hours of corrosion resistance in salt spray tests. Our ceramic-coated medical components comply with FDA biocompatibility requirements, making them safe for use in implants and surgical tools.
Tolerancias: The Precision We Deliver
Tolerancias are critical in CNC Boring—even tiny deviations from the specified dimensions can affect a part’s performance (p.ej., a loose fit in a bearing seat can cause machinery vibration, while a tight fit can lead to assembly issues). Our CNC Boring process is optimized to achieve ultra-tight dimensional tolerance and smooth rugosidad de la superficie, consistently exceeding industry standards.
Nuestras capacidades de tolerancia vs.. Promedios de la industria
| Métrica | Nuestra capacidad | Promedio de la industria | Ventaja |
| Tolerancia dimensional | ±0.0003” (0.0076 milímetros) | ±0.0010” (0.0254 milímetros) | 3x tighter tolerance for high-precision applications |
| Rugosidad de la superficie (Real academia de bellas artes) | 0.4 – 2.0 µm | 2.0 – 5.0 µm | Significantly smoother surface for reduced friction and improved part longevity |
| Positional Tolerance | ±0.0005” (0.0127 milímetros) | ±0.0020” (0.0508 milímetros) | More accurate alignment of bored holes with other part features (p.ej., agujeros de montaje, tragamonedas) |
To maintain these strict tolerancias, we use CNC boring machines equipped with linear encoders (exactitud: ±0.00005” per foot) and laser calibration systems. We also perform in-process inspections every 15 parts—using bore gauges and CMMs—to catch any deviations early and ensure consistencia across the entire production run.
