Differences Between CNC Turning and CNC Milling
While both CNC turning and milling are essential machining processes, they differ significantly in operation. In CNC turning, the workpiece rotates while the cutting tool remains stationary, making it ideal for cylindrical shapes. Conversely, CNC milling keeps the workpiece stationary while the cutting tool rotates, suitable for both symmetrical and non-symmetrical shapes.
Key Differences
| Feature | CNC Turning | CNC Milling |
|---|---|---|
| Workpiece Movement | Rotates while cutting tool is static | Stationary workpiece with rotating tool |
| Ideal Shapes | Cylindrical and conical | Flat and complex geometries |
| Cutting Tools | Single-point cutting tools | Multi-point cutting tools |
| Applications | Shafts, pins, and cylindrical parts | Flat surfaces, intricate designs |
