Surface grinding is used to produce a smooth finish on flat surfaces. It involves a rotating grinding wheel that removes material from the workpiece, achieving tight tolerances and a fine surface finish.

This process is used for grinding the outer surface of cylindrical parts. The workpiece is rotated between two centers while a grinding wheel removes material, achieving precise diameters and tolerances.

Centerless grinding is a method where the workpiece is held between two wheels, without the need for centers. It’s commonly used for parts that require high precision and is ideal for mass production of cylindrical parts.

Internal grinding is used to grind the inside diameter of a workpiece. It is often performed on components like tubes, cylinders, and bearings, requiring high accuracy on the inner surface.
