What Is CNC Gear Machining?
Mecanizado de engranajes CNC is a computer-controlled manufacturing process that produces gears—mechanical components with toothed surfaces that transmit torque and motion between machine parts. Unlike manual gear cutting (which relies on operator skill and is prone to inconsistency), Mecanizado de engranajes CNC uses pre-programmed Tecnología CNC to automate cutting, organización, y acabado, ensuring repeatable precision.
En su núcleo, el Gear Machining Process involves removing material from a workpiece (usually metal) to create teeth with specific profiles (P.EJ., involute, cycloidal) y dimensiones. Gear Manufacturing via CNC integrates software (CAD/CAM) and advanced machines to control every step—from tooth spacing to tooth depth—making it ideal for both standard and custom gear designs. Whether for small hobbyist parts or large industrial gears, CNC ensures accuracy that manual methods can’t match.

Proceso: The CNC Gear Manufacturing Steps
El CNC Gear Machining Process follows a structured sequence to ensure consistent quality and performance. Below is a step-by-step overview of our Gear Manufacturing Steps, from design to finishing:
- Diseño & Programación: We start with your 2D/3D CAD model (P.EJ., PASO, IGES) and use CAM software to create a CNC program. This program defines key parameters: gear type, module, number of teeth, cutting tool path, and feed rates—all tailored to your gear’s function.
- Preparación de material: The chosen material (P.EJ., acero, latón) is cut into blanks (cylindrical or conical shapes) y tratado con calor (si es necesario) to improve hardness before machining.
- Mecanizado áspero: Using CNC hobbing or shaping machines, we remove excess material to create the basic gear shape. For external gears, hobbing is common; for internal gears, shaping works better. This step gets the gear 80–90% close to its final form.
- Terminar mecanizado: We use precision tools (P.EJ., gear shapers, muelas) to refine the teeth. This step corrects small errors from rough machining, ensuring accurate tooth spacing, profile, and surface smoothness.
Gear Finishing Process: Depending on requirements, we add Acabado superficial (P.EJ., molienda, lapping) Para reducir la fricción y el uso. We also inspect the gear for dimensional accuracy using tools like gear testers.

Técnicas de fabricación: Métodos avanzados que utilizamos
To deliver top-tier gears, Usamos de vanguardia Gear Manufacturing Techniques y Machining Techniques. Below are our core methods:
- Tallado CNC: The most common method for external gears (spurs, helicals). A rotating hob (cutter with spiral teeth) cuts gear teeth as the workpiece spins. Ideal para producción de gran volumen (P.EJ., engranajes automotrices).
- CNC Gear Shaping: Uses a reciprocating cutter (shaper) to create internal or external gears. Better than hobbing for complex shapes (P.EJ., engranaje interno, gears with shoulders).
- CNC Gear Grinding: A finishing technique that uses abrasive wheels to refine teeth. Achieves ISO grade 4–5 accuracy and ultra-smooth surfaces—critical for aerospace or precision instruments.
- 5-Mecanizado CNC del eje: For complex gears (P.EJ., engranajes de bisel, spiral gears). The 5-axis system adjusts the workpiece’s angle in real time, ensuring accurate tooth profiles on all sides.
EDM de alambre (Mecanizado de descarga eléctrica): Used for micro gears (module <1 milímetros) or hard-to-machine materials (P.EJ., titanio). Uses electrical sparks to cut teeth without physical contact—ideal for intricate designs.
