 Flatten, Trim, & Pierce
 This punch press operation is a cost-effective way to produce a flat tube end for tubular assemblies. Using a dedicated die set, this process combines three separate operations, flattening the end of the tube, trimming the end corners, and piercing a hole pattern for fastening the tube.
As illustrated in the graphics, this process can also incorporate a variety of shapes by forming the flattened end. These shapes include cupped or curved ends
