Grinding Wheels

4.1 INTRODUCTION 4.1.1 Developments in Productivity Huge increases in productivity have been achieved in recent decades due to advances in grinding wheel technology. These increases have only been possible by parallel developments in the machines and auxiliary equipment employed since the greatest gains have been from the grinding system. Grinding wheels operating at low wheel […]

Phenolic Resin Bonds for Superabrasive Wheels

For superabrasive wheels, phenolic resin bonds represent the earliest, and most popular, bond type particularly for diamond wheels and especially for tool-room applications. The bonds were origi­nally developed for diamond with the introduction of carbide tooling in the 1940s. Their resilience made them optimal for maintaining tight radii while withstanding the impact of interrupted cuts […]

UNIAXIAL TRAVERSE DRESSING OF VITRIFIED CBN WHEELS WITH ROTARY DIAMOND TOOLS

7.5.1 Introduction The rules for dressing vitrified CBN wheels are similar in many ways to those described for conventional wheels. The same concepts of crush ratio, traverse rates, effective contact width, and depth of cut apply. The changes that must be made to the dressing conditions relate to the greater hardness, toughness, and cost of […]
