Why is the machine tool used for sheet metal fabrication

The workpiece produced with this technique has a small bending radius, no obvious color changes, and small bending force requirements. In addition, it reduces the straightness error of the round edge of narrow long workpieces, and the common press brake and tooling can be used to bend the workpiece with a complicated section shape.
Why should workpieces be v-cut before bending?
● The bending radius of the workpiece should be small;
● The bending angle of the workpiece bending with stainless steel titanium sheet metal or other colored metal sheet metals should not have serious color changes;
● No obvious color difference is allowed;
● The curved section of the workpiece is more complicated;
● The unique style of the designer should be displayed.
Traditional bending methods such as forced bending, free bending, and even three-point bending have been unable to meet the above requirements.
In other words, bending the metal sheet with a press brake alone cannot meet the design requirements of the designer and cannot achieve the grade and decorative effect of middle and high-grade decoration.
Therefore, a novel bending technique has been developed, which is V-groove bending technology.
