Definition & Basics
CNC (Computer Numerical Control) lathe machining automates the rotation of a workpiece against stationary cutting tools, following pre-programmed G-code instructions.
Traditional manual lathes rely on operator skill; CNC lathes eliminate variability by executing repeatable, micron-accurate toolpaths.
Key Benefits
Micron-Level Tolerances (±0.005 mm typical)
Repeatability across hundreds or thousands of parts
Reduced Setup Times with automated tool and work offsets
| Capability | Benefit |
|---|---|
| High-Speed Spindles | Up to 12,000 RPM for rapid material removal & fine finishes 😊 |
| Multi-Axis Control | 2- to 5-axis for undercuts, tapers & complex profiles |
| Live Tooling & Y-Axis | On-lathe milling, drilling & grooving—fewer setups |
| Automated Bar Feeders | Continuous lights-out operation for medium to high volumes |
