Grinding and polishing are the same mechanical movement, the principle is the same. But for surface quality, the surface finish of polishing is higher than that of grinding. In fact, polishing fluid can be said to be the last process of grinding, grinding and polishing can be realized on the same plane polishing machine at the same time. Grinding is divided into rough grinding, fine grinding, polishing is divided into rough throwing, fine throwing. Most of the time, we have three processes to process the surface quality of products: rough grinding, fine grinding, fine polishing. With these three processes, the workpiece surface flatness, parallelism, roughness is quite high. Some customers do not have such high accuracy requirements, especially roughness requirements are not so high, so they only use the first two processes, or the fine grinding process. Specific to see the quality of the workpiece surface itself, as well as customer requirements to achieve the quality.
