structural additives for high speed grinding wheels


Posted on November 16, 2018



structural additives for high speed grinding wheels,All grinding wheels are made up of two components-abrasive grains .The relative percentage of abrasive and bond, and their spacing within the wheel, impart a characteristic known as structure. These spaces, or pores, provide clearance for the chips produced by the abrasive grains and contribute to a faster, cooler cutting action. Wheels used for profile knife grinding of high-speed steel are.structural additives for high speed grinding wheels,Innovations in Abrasive Products for Precision Grinding .This paper is a review of recent developments in the design and manufacture of precision, fixed-abrasive tools. The role of each component within the “engineered composite” is also discussed, with examples showing how the components have been enhanced to achieve their current high levels of performance. The paper.
