Gearbox shaft: turning, hobbing, hardening, grinding, measuring
A geared shaft whose whole route, including case hardening at an approved supplier, runs under our quality system: the blank is turned and the teeth hobbed in-house, hardened parts pass incoming inspection in our own laboratory, and the shaft is then ground and measured.

Route
| Step | Machine | Check |
|---|---|---|
| Sawing | Saw | Length |
| Turning | Twin-spindle CNC lathe or multitasking centre | Diameters, lengths |
| Gear hobbing | SMG SH-260 (6-axis CNC) | On request |
| Keyway / spline | Broaching or milling | Gauge |
| Case hardening | Approved supplier | On request |
| Cylindrical grinding | Grinding machine | Roundness, roughness |
| Final inspection | CMM with gear module, contour measuring device, hardness tester | Full report |
| Marking and packing | Laser marking | Batch traceability |
Why it matters
Because blank turning, gear cutting, and dimensional and hardness inspection stay in-house, the two usual delays in geared parts — external blank supply and inspection queues — are avoided.
