摘要：
This paper discuss the wear behavior of cBN grain cutting edges in deep grinding. To make the topographic features of the wheel working surface in deep grinding clear, changes in the shapes of the grain cutting edges are observed by a scanning electron micro scope. The wear characteristics are evaluated quantitatively using attritious wear flat percentage. The wear behavior of grain cutting edges are divided into two main types. A type of the wear behavior of the grain cutting edges generated micro fractures and the changes in attritious wear flat percentage was stable. Another type caused many wear flat areas and attritious wear flat percentage increased sharply during grinding process. The result are closely related to the changes in grinding forces and the workpiece surface roughness. © 2020 Japan Society for Precision Engineering. All rights reserved.
