What Is the Hardest Thing About Bending Long Rods?
Short answer: Keeping the long span straight. This video shows Q235 bright steel rods bent into large crank links on a CNC machine - the long bar is supported so the span between offsets stays dead straight and the bright surface stays unmarked.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Long rod supported | No sag |
| 2 | First offset | Exact position |
| 3 | Second offset | Crank done |
| 4 | Hand span check | Straightness proven |
Key Applications
- Long linkage and tie rods
- Frame spreaders and braces
- Machinery crank shafts
