6mm Iron Rod Double Offset Cranks on 3D CNC
High-precision 3D CNC bending of 6mm iron rods into compact double-offset crank pins - small heavy parts formed in one clamping.
Key Specifications
- Materials
- Iron rod, 6 mm
Key Features
- Both offsets formed without reclamping
- Compact cranks with tight leg spacing
- Servo feed locks every dimension
- Clean sheared ends off the machine
How Small Can a 3D Crank Get?
Short answer: Smaller than you would bend by hand. This video shows 6mm iron rods formed into compact double-offset crank pins on a 3D CNC machine - both offsets made in one clamping, legs spaced to the tenth of a millimeter.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Rod fed and clamped | One setup |
| 2 | First offset | Crank start |
| 3 | Second offset | Compact Z done |
| 4 | Hand check | Spacing proven |
Key Applications
- Machinery crank and shift pins
- Lock and latch linkages
- Non-standard connector parts
Why One Clamping Matters
| Reclamped offsets | One clamp (shown) |
|---|---|
| Datum shifts between | Single reference |
| Legs drift apart | Spacing locked |
