Do you know what is External Cylindrical Grinding?

External cylindrical grinding is one of the most common grinding processes and is mainly used for grinding rotationally symmetrical workpieces. It differs in the type of workpiece clamping and feed directions: ---Peripheral-cross grinding between centers (plunge grinding) ----Peripheral-longitudinal grinding between centers (oscillation grinding) ----Centerless-peripheral-cross grinding (centerless plunge grinding) ----Centerless-peripheral-longitudinal grinding (centerless through feed grinding)
