16.04.2021Grinding 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.
