Continuous generating grinding is one of the most productive technologies to grind high precision gear tooth flanks. KAPP manufactures dressing tools in positive and negative electroplated version. Highest flexibility can be achieved with form rolls for topological dressing. For the so called ?flexible dressing? the tools are designed to dress worms for different workpieces with one tool, while the tip of the worm is dressed separately. For serial production there are profile rolls with integrated tip dresser, in a workpiece specific manner also for grinding of well defined gear root area. Most productive for high volume are multi-ribbed diamond profile rolls manufactured in a negative electroplating process, whereby the dressing times can be reduced up to 60 %.
