Sheeting Cutting Machine

A sheet metal machine is used to cut, press, bend and form sheet metal into various shapes and sizes.The most popular traditional sheet metal techniques are shearing-type cutting (e.g. punching), waterjet, plasma, EDM, and lasers. Waterjet cutting was commonly used in industrial applications in the 1930s, while EDM and plasma cutting made their debuts in the 1960s. Laser cutting was introduced in the 1970s.The three major categories of sheet-metal processes are (1) cutting, (2) bending, and (3) drawing as shown in figure (9.2). Cutting is used to separate large sheets into smaller pieces, to cut out part perimeters, and to make holes in parts.A brake is a metalworking machine that allows the bending of sheet metal. A cornice brake only allows for simple bends and creases, while a box-and-pan brake also allows one to form box and pan shapes. It is also known as a bending machine or bending brake or in Britain as a sheet metal folder or just a folder.
