  • Grinding (Machining) - an overview | ScienceDirect Topics

    Grinding is a machining process which removes material in a finishing regime. Heat treatment is the final step of many process chains, and it is usually expensive and time-consuming. To shorten these process chains, the concept of grind-hardening has come up [24]. The idea consists of substituting a conventional hardening process with the "grind-hardening" process.
