Abstract
In the last years the demand for grinding machines of large module gears increased very strong. New productive solutions were developed. The profile grinding technology was improved. By using the fast feed rate grinding it is possible to do rough grinding with much higher specific metal removing rates. Also the non-productive auxiliary times are reduced. Before grinding the gears they are measured completely with high-speed measuring. Based on these results the grinding process will be optimized to prevent grinding times without contact of grinding wheel and gear. Another possibility to increase quality and productivity is the combination of processes in one machine. The grinding of the gear teeth, the bore and the face of a planetary gear will be executed in one machine. The results are presented. The continuous generating grinding was further developed. Now it is possible to grind large module gears up to a gear diameter of 1000 mm and a module of 10. The productivity could be increased significant. The specifics and the problems in comparison with profile grinding are discussed. An outlook to future developments is given.
