CNC punch presses are programmed to move a sheet in an “x” and “y” direction, so as to position sheet under the machine’s punching ram.
They can now achieve speeds of up to 1000 hits a minute and utilize servo-electric rather than hydraulic actuation, for greater accuracy.
The processing range for most punch presses is .5mm to 6mm thick, in a range of materials including: mild steel, galv., stainless steel, aluminium …
The choice of hole can be as simple as a circle, or rectangle right through to special shapes: by a combination of single hits and overlapping geometries, even complex component shapes can be made.
(Generally punch presses can also punch 3D forms: such as screw thread plunges, el. knockouts etc. -- Some have the ability to tap threads, fold small tabs, punch sheared-edges … without any tool witness marks.)

Vs. sheet punching machines, coil-fed punching systems offer notable advantages such as: - reduced cost of material and scrap quantity, - generally a higher production, - and less floor space requirement.
