What is Spherical Lapping? The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.

Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between

Spherical grinding typically uses a cup grinding wheel containing segmented abrasive blocks that continually engage the surface of the sphere workpiece during grinding. In this study, the trajectory of the abrasive grain, undeformed chip thickness, and the grinding mechanism are considered separate from the surface grinding process.

The process of grinding lens or mirror surfaces produces spherical surfaces because those are the only ones that can be slid around over each other perfectly. So unless you really need it, it's easier to get by with a sphere and spherical surfaces are still the norm unless you go and specify an asphere.

Fig. 1 shows the SEM images of the PCD tool with a simple spherical shape after being developed with a diamond grinding wheel. As a result, a new spherical PCD tool with a ground surface after finished by grinding, it was obtained a high accuracy of the contour radius and a surface roughness of 0.179 μmRa/0.924 μmRz.
