Grinding burn is a general term used to describe various types of thermal damage that occur to the workpiece during grinding. The author supplies detailed information about each type of burn and offers advice for preventing it

Discussion of different types of bonds used to make superabrasive grinding wheels. Author provides tables with price comparisons, physical properties and operating parameters for various bonds.

GE Superabrasives' silver-coated diamond crystal is designed for grinding tungsten carbide. Discussed are the benefits--reduced friction, greater crystal retention and a cooler grinding environment--and how to apply wheels made from the crystal.

Creep-feed grinding is not as popular a process as it was predicted to become in the late 1980s. But a machine shop that specializes in CF grinding has found great success by using the process. The shop's owner and other CF-grinding experts contend that as workpiece tolerances become tighter and manufacturers begin using more exotic workpiece materials, CF grinding will grow in popularity.

This article makes the argument that grinding is still a useful and necessary process despite the advancements that have made the turning of hardened workpieces possible. The article discusses the precision and finish possible with grinding, and it compares the cost of grinding to other machining processes.

The fundamentals of wheel dressing and truing are reviewed in this article, which covers the proper maintenance of a wide variety of wheel bonds and abrasive types. The article also discusses different truing techniques and their appropriateness for different uses.
