This animation shows the press quenching process of a through hardened bearing ring, which was experiencing quench cracking. The DANTE simulation showed high in-process tensile stresses at the bearing race (location of cracking). The martensite transformation in the core, along with friction from the dies, was determined to be the cause of cracking. Load pulsing of the press equipment was used to nearly reduce the quench cracking after learning the causes of cracking from the DANTE simulations.
