FAQ

Q: How do I select the correct V-die opening for press brake bending?
A: The appropriate V-die opening depends mainly on material thickness, bending requirements, and the desired inside bend radius. Choosing the correct die opening helps control bending force, angle accuracy, and surface quality.
 
Q: What happens if the bending sequence is not properly planned?
A: An unsuitable bending sequence can cause workpiece interference, difficult positioning, or unnecessary handling between operations. Planning the sequence before production helps avoid these problems and makes the bending process more efficient.
 
Q: What's the shipping cost from china to your country?
A: We can send machine to your port or door address by sea or airplane. please kindly tell us your nearest port or address with postcode. we have reliable shipping agent to insure the safe convenient and time delivery.
 
Q: What should I do if the finished bending angle is different from the programmed angle?
A: The first step is to check the material, tooling, sheet thickness, positioning, and machine settings. Material springback can also affect the final angle. If necessary, the bending parameters can be adjusted after testing the first workpiece.
 
Q: Why does springback occur during press brake bending?
A: Springback occurs because metal tends to partially return toward its original shape after the bending force is released. Its effect depends on material properties, thickness, bend radius, and bending conditions.
 
Q: Can the press brake work with pre-cut parts from a laser cutting machine?
A: Yes. Laser-cut sheet metal parts can be transferred directly to the press brake for forming after cutting and necessary preparation. This combination is commonly used to create complete sheet metal components.
