Punching

The punching process produces shapes by selectively removing material from sheet metal. These sheets are clamped into the machine on a table that is programmed to move to a specific X/Y location within the matrix of the machine. Features such as knockouts, louvers, and dimples can be incorporated on sheet metal parts according to customer specific requirements. A punch press can be a huge cost savings opportunity, By driving multiple holes in a part with a single ‘hit’, not only is speed and accuracy enhanced, but a valuable saving in processing time and money too. Other advantages of punching include high precision, consistent quality, large processing format and multi-axis linkage. For example, compare the speed of a nail gun to a screw driver. A nail gun can drive a hole and fill it with a fastener with one pull of the trigger.

A screw and screw driver however takes more time and effort to achieve a similar result. Our presses are like having multiple nail guns working together at once – it can punch multiple holes in one quick stroke. At CNC we apply the latest punching technology for superior speed and accuracy in processing small, medium and large sheets. Our CNC punching machine allows for a maximum productivity gain whilst minimising material scrap. This maximises efficiency and allows us to provide customers with consistent, cost effective solutions. We use AutoCAD and Sheetworks for downloading customer drawings and AP100 for programming. The parts created during this process could then be sent for post processes such as bending, welding and assembly
