Long tool life
25.3.7
Extending the service life of tools is another approach to increasing material efficiency. This can be achieved through a variety of measures, including using lower-wear tool materials, adjusting tool geometry, automatically monitoring tool wear, improving cooling lubricants, and selecting more processable materials.
A detailed understanding of the contact normal stresses in the forming zone is of particular importance. Modern designs of the radii on drawing rings can have a positive influence on the adhesion and abrasion behavior of the friction partners, which reduces tool wear and thereby extends their service life.
