Beside the non-dressable CBN grinding tools, dressable grinding tools of leading manufacturers can be used on our machines, too. Vitrified bond aluminium oxide tools are dominant. Sintered aluminium oxide is preferred as the grinding tool for grinding of steel due to its resilience and grinding capability. Gray cast-iron can also be processed with normal aluminium oxide. The profiling of the grinding tools takes place via a machine-integrated CNC dressing unit. A diamond-plated, rotating dressing tool profiles the wheel in accordance with the respective gear parameters. The grinding tool is conditioned specifically for rough or finish grinding by selecting respective technological dressing parameters. Form consistency and cutting capacity of the grinding wheel is assured by repeated dressings, dependent on pre-defined stock removal rates. The automatic balancing produces smoother turning for larger grinding tools, and consequently, high gear quality. dressable CBN tools Single-layere

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 made in a negative electroplating process.
