Abstract: Today, CBN grinding wheels are prevalently dressed with form rollers. Hence, the improvement of dressing with form rollers by using new methods is of particular interest. Although ultrasonic assistance has been successfully used for a long time in different machining processes, the ultrasonic assisted dressing with form rollers has not yet been realised for technical and economical reasons. The ultrasonic assisted dressing with form rollers was developed for the first time at the KSF Institute using a special dressing spindle that is introduced in this article. The results obtained through the experimental investigation depict significant improvements with utilising ultrasonic assistance in dressing with form rollers. This is realised when the dressing parameters are properly set.

Keywords: grinding wheel dressing; form rollers; diamond; CBN grinding wheels; ultrasonic spindles; ultrasonic-assisted dressing.
