Metal bending brakes are invaluable tools for shaping and forming sheet metal. However, even these powerful machines can encounter occasional glitches. When bends go awry or precision eludes you, it’s time to delve into the troubleshooting abyss.

1. Uneven Bends:

Unequal pressure distribution can lead to wobbly, uneven bends. Check for:

Clogged or faulty pressure relief valves

Worn or damaged hydraulic hoses

Loose or misaligned bending fingers

2. Heavy Springback:

Springback, the tendency of metal to return to its original shape, can be exacerbated by:

Incorrect springback compensation in the machine settings

Too high or low clamping pressure

Metal with high residual stress

3. Scratches or Marks on the Bend:

Protecting the delicate surface of sheet metal is crucial. Look for:

Dirty or damaged bending fingers

Abrasive burrs on the machine

Insufficient lubrication between the metal and bending fingers

4. Lack of Precision:

Precision bending demands accuracy. Potential causes of imprecise bends include:

Loose or worn guides

Misaligned bending fingers

Excessive backlash in the gearbox

5. Machine Malfunctions:

Severe issues require professional attention. Seek immediate assistance if:

The machine fails to respond to commands

Hydraulic fluid leaks

There are loud or unusual noises

Troubleshooting Tips:

Start with the simplest possible solution.

Inspect the machine thoroughly before attempting any adjustments.

Refer to the manufacturer’s manual for specific troubleshooting guidelines.

If the problem persists, contact a qualified technician.

By following these steps, you can diagnose and resolve common issues with metal bending brakes, ensuring that your bending operations run smoothly and produce pristine results.
