External Cylindrical Grinding

External Cylindrical grinding, cylindrical grinding is mainly carried out on an external cylindrical grinding machine, which is used to grind the outer cylinder, outer cone and shoulder end surface of shaft-type workpieces. During grinding, the workpiece rotates at a low speed. If the workpiece reciprocates in the longitudinal direction at the same time and the single-stroke or double-stroke movement in the longitudinal direction moves the grinding wheel relative to the workpiece, it is called longitudinal grinding.

Cylindrical grinding is mainly carried out on an external cylindrical grinding machine, which is used to grind the outer cylinder, outer cone and shoulder end surface of shaft-type workpieces. During grinding, the workpiece rotates at a low speed. If the workpiece reciprocates in the longitudinal direction at the same time and the single-stroke or double-stroke movement in the longitudinal direction moves the grinding wheel relative to the workpiece, it is called longitudinal grinding. If the width of the grinding wheel is greater than the length of the surface to be ground, the workpiece does not move longitudinally during the grinding process, but the grinding wheel continuously feeds the workpiece continuously, called the plunge grinding method. The efficiency of the plunge-cut grinding method is generally higher than that of the longitudinal grinding method. If the grinding wheel is trimmed into a forming surface, the plunge grinding method can be used to process the formed outer surface.
