8mm 35CrMoV Crank Hooks Bent on 3D CNC
High-precision 3D CNC bending of 8mm 35CrMoV alloy steel rods into crank hooks - springback-true heavy parts for demanding hardware.
Key Specifications
- Materials
- 35CrMoV alloy steel rod, 8 mm
Key Features
- Tough alloy bent springback-compensated
- Crank legs angled in the same clamp
- Hardened tooling resists alloy wear
- High-strength parts for latch duty
Why Does Alloy Steel Need Harder Tooling?
Short answer: It eats ordinary dies. This video shows 8mm 35CrMoV alloy rods bent into crank hooks on a 3D CNC machine - hardened tooling and programmed over-bend keep the tough alloy true.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Alloy at hardened die | Wear managed |
| 2 | U body swept | Over-bend set |
| 3 | Crank legs angled | 3D done |
| 4 | Bin check | Springs back true |
Key Applications
- High-strength crank and latch hooks
- Tool and die hardware
- Machinery linkage arms
Mild vs Alloy at the Die
| Q235 mild | 35CrMoV alloy (shown) |
|---|---|
| Standard tooling | Hardened tooling |
| Low springback | Programmed over-bend |
| Final strength far higher |
FAQ
Can parts be heat treated after? Yes - tempering preserves the bent geometry.
What alloy sizes run? 4mm to 16mm by machine class.
