结合剂对CBN砂轮的性能影响很大。在结合剂中掺入固体润滑剂,如PTFE(聚四氟乙烯)将有助于减少工件与砂轮接触面间的摩擦,能促进切屑的形成,使砂轮不易被切屑所堵塞,还有助于保持各个磨粒的刃口的锋利性。在韩磨削用CBN砂轮的结合剂中加入325目或更细一点的银粉,将有助于使砂轮工作面所吸收到的磨削热迅速导入基体,藉辐射和空气冷
The binding agent has a great influence on the performance of the CBN grinding wheel. The incorporation of solid lubricants, such as PTFE (polytetrafluorethylene), into the binder will help to reduce friction between the workpiece and the wheel contact surface, promote chip formation, prevent the wheel from becoming clogged by the chips, and help Maintain the sharpness of the edge of each abrasive grain. Adding a 325 mesh or finer silver powder to the bonding agent of the grinding wheel with the CBN grinding wheel in Korea will help to rapidly introduce the grinding heat absorbed by the work face of the grinding wheel into the substrate and radiating and air cooling
