¿Qué es el torneado CNC??
Basics of CNC Turning
CNC turning is a machining process where a workpiece gira a altas velocidades while a stationary cutting tool removes material. This method is best suited for cylindrical or rounded components such as shafts, boquillas, and rings.
Unlike manual lathes, CNC turning is fully automated and controlled via computerized programs, ensuring high precision and efficiency.
How CNC Turning Works
- Configuración de la pieza de trabajo: The machinist secures a cylindrical workpiece into a arrojar on the CNC lathe.
- Rotación: The chuck spins the workpiece at high speeds.
- Cutting Tool Movement: The cutting tool moves along the X and Z axes, shaving off material to create the desired shape.
- Múltiples operaciones: CNC turning allows for additional processes such as perforación, aburrido, nudoso, and threading.
- Completion: Una vez que el mecanizado está terminado, the component is removed, limpio, and quality-checked.
CNC Turning Operations
CNC turning machines can perform several operations, incluido:
- Frente a: Cutting the end of the workpiece to make it flat.
- Aburrido: Enlarging an existing hole.
- Perforación: Creating cylindrical holes in the workpiece.
- Knurling: Producing textured patterns for better grip.
- Torneado cónico: Creating a conical shape.
- Corte de hilo: Carving screw threads into the workpiece.
