Combination Cutoff Dies - by Paul Williams

Although cutoff dies are available in many variations, one thing most have in common is

their function: cutting a tubular shape to length. In most cases, this is all that is required.

Sometimes, however, suppliers are looking to take the next step and add value to their

products; adding subsequent operations can go a long way.

Determining the right die for the operation is based on the following criteria:

•   Part Shape

•  Material Thickness

•  Die Maintenance

•  Line Speed

•  Press Stroke

• Matchup of Prenotched Areas

•  Run Lengths

Only experience can tell you what can or cannot be done and what types of part cutoff

operation are achievable. Much depends on the part’s contour, required end condition,

forming operation (welded, lockseam, overlap), and value-added operations such as

adding notches, holes, and forms.

The maximum benefits and profits are achieved when dies are used not only for cutoff,

but also to punch or form the part from the mill, eliminating all secondary operations.
