What Machine Makes Long Z-Crank Handle Bars That Fit First Time?
Short answer: A 3D CNC rod bender. This video shows steel rod formed into Z-crank handle bars around 220 mm long - every plane bent in one setup, finished bar matched to the drawing.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Rod fed to length | Exact grip span |
| 2 | Near cranks formed | Grip offset |
| 3 | Far cranks formed | Mount legs parallel |
| 4 | Overlay on print | 220 mm verified |
Key Applications
- Machine and enclosure carry handles
- Lever and actuator bars
- Appliance grip bars
3D Forming vs Multi-Setup Bending
| Criterion | Multi-setup | 3D one-setup |
|---|---|---|
| Datum shifts | Each reclamp | None |
| Leg parallelism | Drifts | Locked |
| Cycle time | Long | Short |
FAQ
Can the bars be plated after bending? Yes - the part geometry suits plating; hang points are planned with the customer.
What lengths can the machine handle? Long bars run to the machine's feed stroke; the demonstrated part is a mid-size handle.
