TLDR
In this article, the impact of different grinding parameters on the structure and the achievable hardness penetration depth are discussed in detail, especially the impact on the hardness penetration depths of different grinder parameters.Abstract:
The invention of advanced grinding processes enabling the surface hardening of steel parts was described for the first time in 1994 [1]. In such operations, named grind-hardening the dissipated heat in grinding is utilized to induce martensitic phase transformations in the surface layer of components. A grinding process then becomes a heat treatment operation like induction or flame hardening. The fundamentals of this new process, which had been developed up to first industrial applications, will be illustrated in this paper. Especially the impact of different grinding parameters on the structure and the achievable hardness penetration depth are discussed in detail.read more
