Punching Press Machine

punch press, machine that changes the size or shape of a piece of material, usually sheet metal, by applying pressure to a die in which the workpiece is held. The form and construction of the die determine the shape produced on the workpiece. These machines are usually equipped with a linear matrix carrier (tool holders) and quick change tools. The numerical computerized punching (CNC) is a manufacturing process of sheet metal that is made by CNC punching machines.If someone is 'punching', that means that they are 'punching above their belt', or in other words the person they are talking to or dating could be thought of as more attractive than them. (Tom is really being ambitious right now. He's talking to Jacob – the hottest boy in school – Tom is definitely punching.)
