Grinding (Surface, Cylindrical, Tool & Cutter)

Grinding research has led to innovations in wheels and machines, which have expanded the range of applications grinding can be used for. This article highlights some of the research being conducted and the work that has made it to the shop floor. An accompanying article discusses CBN abrasives.

Tantalum and Niobium are important components in the composition of carbide tools. They are also among the most expensive. This article explores how recent trends in metalcutting and tool usage will effect the supply of these two components.

The presence of bacteria and fungi can seriously compromise the effectiveness of metalworking fluids. This article looks at the most harmful microbes and the conditions that allow them to flourish. Preventive measures are also discussed.

Segmented grinding wheels can help in heavy stock-removal applications with large contact areas. This guide covers where grinding segments fit and what shops should watch.

This article traces the changes in countersink design and materials that have been made to satisfy the demands of the aerospace industry. The advantages and disadvantages of different types of modern countersinks are discussed.

A CNC tool grinder connected to an automated loading unit can be programmed to grind tools during a shop's off hours. This article discusses the planning and preparation that are necessary to set up an unattended run.

CBN grinding wheels offer the promise of higher productivity and longer wheel life, but they must be carefully maintained with dressing routines that differ from routines for standard wheels. This article details the techniques and tools needed to perform CBN wheel dressing effectively and economically.

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.

Researchers at the Center for Grinding Research performed a series of creep-feed grinding tests to determine the causes of the heat damage and striations they observed. The tests involved grinding slots and vertical faces. This report discusses the dynamics behind these problems and suggests ways to avoid them.

Standards governing grinding-wheel safety testing do not cover all superabrasive wheels. This article suggests that these standards should include them. The author explains why as he describes a typical superabrasive wheel and the dynamics of superabrasive wheel failure.

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.
