What is v cutting bending?  The v cutting is the 90 degrees v shape groove cut on the metal sheet before the bending, and then use it as the bend line, the goal is to have the good appearance of the edge of the decorative metal product like metal screens, door,etc. Normally the depth of the v cutting is half of the sheet thickness. It is the previous work on bending. Yes, you can bend the metal by the bending machine directly without the v cut, but in the decorative industry, the v cutting process is necessary.




There is radius of the bending corner after bending, it is more obvious and the radius is bigger if the material is thicker. It is ugly and not qualified for the decorative products, so people developed the v cutting technology. The metal after v cutting is easy to be bent, for the thin metal you can even bend the sheet by hands along the v cutting line, also the corner is very sharp which makes the decorative metal products looks neat, this is the point of the v cutting bending process.

For example, the frame of the stainless steel door needs the v cutting bending technology; otherwise it would be not good looking if there is a big radius as it is always can be seen and normally it is for the luxury decoration occasions. For the decorative sheet metal products used to cover the wood, the v cutting is necessary and only the sheet after v cut can be bent easily if the bending length is little.

Although the v cutting bending is much helpful but it is not applicable for all the sheet metal products. For the products have the strength requirement cannot use v cut as it would lower the strength, it is only for the decorative metal products which care more about the appearance.
