First published in 1907, this book contains a classic handbook on the subject of 'lapping', a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. It includes chapters on various grinding techniques, as well as how to use abrasives, how to make and use laps, and much more. This volume is highly recommended for those with an interest in machine finishing, and it would make for a handy addition to collections of allied literature. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this book today in an affordable, modern edition complete with the original text and artwork.
