The Development Of Camshaft Lobe Grinding With Vitrified CBN

In 1986 an automobile manufacturer began what was one of the largest R&D experiments in production grinding in recent times; the development of the first high volume line of CBN camlobe grinders in the world. The experiment was a success, achieving productivity and quality levels while progressively reducing tooling costs to below those obtained with conventional abrasive processes. This paper reviews the developments and achievements in camlobe grinding with vitrified CBN.
