CNC Bending&Forming

Bending - sheet metal under Bending machine die or mould, under the pressure of the first through the elastic deformation, and then into the plastic deformation, in the initial stage of plastic Bending, the sheet is bent, freedom as the upper die or mould pressure on sheet metal, sheet metal and die of V type groove surface gradually tight, radius of curvature and Bending arm also gradually become smaller,  Continue to pressure until the stroke is terminated, so that the upper and lower die and plate three points close to full contact, at this time to complete a V bending, is commonly known as bending
