HOW THE SCIENCE OF ABRASIVES YIELDS THE ART OF PERFORMANCE

摘要

On average, the cost of abrasives for large metal fabrication firms is less than two percent while the total cost of grinding and finishing is 10 percent to 15 percent. Cutting abrasive cost may seem attractive, but the reduction of labor costs presents the real upside for the end user. However, there are other less obvious benefits that some grinding wheels provide over others. Grinding wheels for right angle grinders used in metal fabrication have had dramatic increases in performance over the last 20 years. Some of the improvements have come in bond technology and manufacturing tolerances, but the majority of the performance increases have resulted from advances in abrasive grain technology.
