Key Specifications
- Materials
- Cold-drawn steel rod, 10 mm diameter
Key Features
- Forms 10mm solid cold-drawn bar automatically
- Servo feed sets leg lengths precisely
- Rectangular frames come off square every cycle
- Coolant spray extends tooling life on heavy bar
Can 10mm Solid Steel Bar Be Bent Fully Automatically?
Short answer: Yes. This video shows 10mm cold-drawn steel rods formed into rectangular U-frames on a fully automatic CNC bender with servo feed, cut-off and coolant spray.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Bar fed to length by servo | Exact leg dimension |
| 2 | Corner swept with coolant | Clean, sharp bend |
| 3 | Opposite corner formed | Frame squared |
| 4 | Part cut and dropped | Piles of identical frames |
Key Applications
- Door and gate handle bars
- Guard rails and support frames
- Machinery levers in cold-drawn steel
Cold-Drawn vs Hot-Rolled for Bent Frames
| Criterion | Hot-rolled bar | Cold-drawn bar |
|---|---|---|
| Diameter tolerance | +/- 0.4 mm typical | +/- 0.1 mm typical |
| Surface | Scale | Smooth |
| Bend repeatability | Lower | Higher |
| Best for | Rebar, rough parts | Precision frames |
FAQ
What is the heaviest section this machine class bends? Gonger rod bending machines cover up to 16 mm solid sections depending on model.
Does the automatic cut-off leave clean ends? Yes - shear cut-off with deburring handled downstream if required.
