Kornbruchverhalten beim Abrichten von CBN/Fracture behavior of CBN during dressing – Analysis of the single grain dressing process of CBN

wt Werkstattstechnik online, 2021
Die Schleifscheibentopographie, welche durch den Abrichtprozess erzeugt wird, ist ein wesentlicher Einflussfaktor für das Prozessergebnis beim Schleifen. Das Bruchverhalten der Kornwerkstoffe beim Abrichten hängt nicht nur von den Abrichtparametern, sondern auch von dem Korntyp der Schleifscheibe ab.
