What are the benefits of CNC punching?

Punching is the quickest and cheapest way to make a hole in a piece of metal – in this case, aluminium extrusion. It’s a highly repeatable process, which means it’s ideal for large batch runs of identical pieces. The speed and simplicity of the process help cut costs in terms of both machine time and man-hours: the process can be entirely automated, and each punch takes less than a second.
