Grinding Operation - an overview ScienceDirect Topics

The peripheral cut-off grinding process is subdivided into oscillation grinding with a stationary workpiece and rotational cut-off grinding where the workpiece is moving around its longitudinal axis. The main advantage of rotational cut-off in comparison to other techniques is the small contact length.
