Computer numerically controlled (CNC) punching is a sheet metal manufacturing process that is carried out by CNC punch presses.The CNC punching machine is basically programmed to move a sheet of metal in an x and y direction so as to accurately position the sheet under the machine’s punching ram ready to punch a hole or form.
Sheet metal cutting is a major classification for many different pressworking operations. Cutting operations involve the separation of the metal of the sheet in certain areas. This separation is caused by shearing forces acting on the metal through the edges of the punch and die.
Sheet Metal is a metal being formed by a manufacturing process into thin, flat pieces. The sheet metal rolling process consists of passing metal stock through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
Welding is essentially the process of permanently joining two metals together by applying heat. ... As a rule, stainless steel has good weldability, as it can be welded using several different processes, including electron and laser beam, arc, friction, brazing and resistance welding.
Aluminum is a lightweight, thin metal which is used very commonly in welding workshops. With this metal, welding has to be done at low temperatures, or else you will just end up blowing holes in your materials. Aluminum is quite reactive, so forms an oxide layer when it's exposed.
