TECVINA – SUPPORTING INDUSTRIES
By applying a enough shearing force, sheet metal punching is a cutting technique that removes material from a piece of sheet metal. A variety of hole and cut shapes and sizes can be made with CNC punching. The most common punched holes have a simple geometric shape (such as a circle, square, rectangle, etc.) or a mixture of those shapes.
