Internal Cylindrical Grinding. In comparison with other grinding operations, internal cylindrical grinding wheels have to compensate for a number of process-related disadvantages: As a result of the small diameter, there are fewer abrasive grains on the circumference. Each single grain is subjected to a significantly higher load.

In the case of cylindrical grinding, the tool path, and hence the direction of cutting, is determined by the magnitudes of the axial feed rate and the preferal velocity of the workpiece, as previously explained. The direction of cutting (linear preferal velocity of the grinding wheel) is always normal to the tool path, as can be seen in Fig. 3.2.

Cylindrical grinding Cylindrical grinding is the process of grinding the outside surfaces of a cylinder. These surfaces may be straight, tapered or contoured. Cylindrical grinding operations resemble lathe-turning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required.

This grinding operation is carried out only on cylindrical jobs. It is of two types; external and internal cylindrical grinding, an external grinder is used to remove excess material from the outer surface of the workpiece. Whilst the internal is done for smoothening the internal surface of a hole or any cylindrical workpiece. Read:

Cylindrical grinding operations are capable of refinishing both the inner diameter (ID)and the outer diameter (OD)of the workpiece. Form Grinding Form grinding is a specialized type of cylindrical grinding process in which the grinding wheel has the exact shape of the final product. By design, the grinding wheel doesn't traverse the workpiece.
