A common metal process is computer numerically controlled (CNC) punching, which is a manufacturing process that CNC punch presses sheet metal. Using a CNC punch press, the metal is moved from an x to y direction to precisely place the metal underneath the punching ram. This makes for an accurate hole or form for the metal.

The majority of CNC punch presses measures from 0.5mm to 0.6mm thick. The measurement depends on your project as well as your material, which can be Zintec, steel, aluminum, galv, or stainless steel. CNC punch presses can make holes that are circles or rectangles, or you can even customize your hole punch to a specific design of your choice.

Some CNC punch designs are very complex. With overlapping patterns, single hits, geometries, and more, sheet metal can be shaped into almost any design. Some people use this same technique to make electrical knockouts, 3D forms, thread plunges, and more. Depending on the CNC punch press being used, you can fold tabs, create threads, make sheared edges, or other tool witness marks.

Where Technology and Design Meet

CNC punch presses use CAM (computer aided manufacturing) technology from the CAD/CAM system. This uses a 2D format, like DXF, DWG, or 3D files. With information in these files, designers can make the flat sheet metal pressing with the proper tooling to make exactly what you’re looking for.

Computers determine a CNC nest, which is the most efficient way to set up components for a certain size of sheet metal. The more components within a sheet metal panel, the more affordable the CNC punching component will be for manufacturers like S&B Metal Products and people like you!
