METHOD FOR MACHINING CORNER OF METAL PANEL

摘要

PURPOSE: A method for machining the corner of a metal panel is provided which beautifies the external appearance of the metal panel, improves productivity thereof and does not require sealant treatment or welding by machining the corner of the metal panel with a material for the metal panel neither being torn apart nor notched. CONSTITUTION: In a corner machining method of a metal panel(1), the method for machining the corner of the metal panel comprises the processes of bending the metal panel according to dimensions in such a manner that the corner of the metal panel is bent and fixed onto a support(3) by leaving about 100 mm of an end part(2a) of the corner of one side of each bending surfaces(2,2'), and vertically rotationally moving a drum shaped roller(4) like an hourglass from up to down so that the corner of the metal panel is machined; and cutting unnecessary metal fractions formed during the machining of the metal panel using the roller.
