Grinding is a crucial technology that employs specific abrasive processes for the fabrication of advanced products and surfaces. Handbook of Machining with Grinding Wheels, Second Edition highlights important industry developments that can lead to improved part quality, higher productivity, and lower costs. Divided into two parts, the book begins with an explanation of grinding behavior and ends with a focus on new and emerging industrial applications.

While the first edition focused on the basics of abrasive machining technology and presented a unified approach to machining with grinding wheels, the second edition ties in the continued need for traditional processes in conjunction with the latest applications. This book highlights new research topics that include: nanotechnology, alternative energy, and additive manufacturing, compares related approaches, and provides numerous references throughout the book.

New in the Second Edition:

- Contains the latest information on abrasives, bonds, and dressing

- Updates classic stability lobes for grinding

- Introduces a new method for tracking dynamic instability in centerless grinding

- Provides a section in the chapter on ultrasonic-assisted grinding, which contains recent work on modelling of the process

- Adds material on fluid cooling

- Presents experimental results for in-process feedback to the grinding process

- Includes new examples on grinding machine technology (particularly for dressing)

A single source reference covering every aspect of the grinding process, Handbook of Machining with Grinding Wheels functions as a definitive guide to grinding technology for both practicing engineers and students studying graduate-level courses (such as abrasive machining; grinding R&D; metal removal processes; machining of brittle materials; and principles of cutting).

Über Autor(innen)

Brian Rowe is considered the father of centerless grinding in addition to other notable research on grinding that includes thermal aspects, dynamic aspects, and fluid-film bearings. He established a laboratory and school dedicated to manufacturing processes at Liverpool John Moores University and is an Emeritus Professor.

Ichiro Inasaki is the dean of the Graduate School of Science and Technology at Keio University, Japan. He has developed a laboratory with outstanding research activities and his "intelligent grinding wheel" is featured in the Noritake Museum and represents one of his best accomplishments and contributions. He led CIRP in 2004/2005 as the president and was granted several awards.

Eckart Uhlmann is professor and director of the Institute for Machine-Tools and Management at Technical University of Berlin, Germany. Dr. Uhlmann received this chaired professorship after a very successful industrial career with Hermes Abrasive in Germany. As the head of his institute he holds the leading position in research on all aspects of abrasive machining with grinding wheels.

Dr. Mike Hitchiner is manager of precision technology at Saint Gobain Abrasives (Norton), the largest grinding wheel company in the world. Mike has devoted all his life to research, development and practical application of grinding processes. He started this activity during his D Phil at the University of Oxford in England, and was later considered "Mr. CBN Grinding" by the precision grinding industry. Today he focuses on working with machine tool builders and developing new grinding processes. He has brought an important industrial perspective to this book, as well as hundreds of applications.
