Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed
Read MoreApr 16, 2021 Grinding is a pretty diverse segment of machining, as the amount of material removal varies. Depending on the grinding attachment and project, both miniscule and larger amounts of material can be removed. For example, grinding can be used to either produce fine finishes or work in larger production environments to rough out large volumes of metal.
