There are two methods for grinding conical surface on universal cylindrical grinder: longitudinal grinding method and plunge grinding method.
During longitudinal grinding, the grinding wheel rotates as the main movement. The feed movements are: the workpiece rotates in a circular feed movement, and the workpiece reciprocates along its axis for longitudinal feed movement. At the end of each longitudinal stroke or reciprocating stroke of the workpiece, the grinding wheel periodically For a lateral feed movement, all the remaining amount is gradually worn away in multiple reciprocating strokes.
When cutting into the grinding, the workpiece only feeds in a circle without longitudinal feed movement, and the grinding wheel continuously makes a transverse feed movement until all the remaining amount of the grinding reaches the required size.
