Abstract

This paper identifies surface finishing (grinding) as a major engineering process in production industries and that emery cloth otherwise know as ";sand paper"; is used for this purpose. The grinding process is discussed in details.
The materials and their sources requires for the production of the emery cloth are discussed and also the physical properties of the materials are considered.
The paper discusses the manufacturing stages of the cloth. Three main stages were identified sand preparation, backing paper preparation and the emery cloth production. Finally the require quality control processes were considered, a detailed cost analysis was carried out and conclusions were drawn.
