PREFACE
Specialization in machine-tool manufacture has been developed to such a
degree that there is need also for treatises which specialize on
different classes of tools and their application in modern practice.
This book deals exclusively with the use of various types of turning and
boring machines and their attachments, and is believed to be unusually
complete. In addition to standard practice, it describes many special
operations seldom or never presented in text-books. Very little space is
given to mere descriptions of different types of machine tools, the
principal purpose being to explain the use of the machine and the
practical problems connected with its operation, rather than the
constructional details. No attempt has been made to describe every
machine or tool which might properly be included, but rather to deal
with the more important and useful operations, especially those which
illustrate general principles.
Readers of mechanical literature are familiar with MACHINERY'S 25-cent
Reference Books, of which one hundred and twenty-five different titles
have been published during the past six years. Many subjects, however,
cannot be adequately covered in all their phases in books of this size,
and in response to a demand for more comprehensive and detailed
treatments on the more important mechanical subjects, it has been deemed
advisable to bring out a number of larger volumes, of which this is one.
This work includes much of the material published in MACHINERY'S
Reference Books Nos. 91, 92 and 95, together with a great amount of
additional information on modern boring and turning methods.
It is a pleasure to acknowledge our indebtedness to the manufacturers
who generously supplied illustrations and data, including many
interesting operations from actual practice. Much valuable information
was also obtained from MACHINERY.
