Grinding is a manufacturing technique for machining surfaces with abrasives. The rotating grinding wheel performs the cutting motion, while the feed motions are conducted by the grinding wheel or the workpiece, depending on the machine concept and grinding process.
The term quot;lappingquot; 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.

Grinding marks on ultra precision grinding spherical and aspheric surfaces. Finally, the large size infrared lens was ground with high surface quality by the optimized grinding parameters, and the results of surface quality demonstrate that the discriminating standard was effective. This research provides references and ideas for grinding aspherical surface with high surface quality and efficiency, low energy and wastage.
