These small gearboxes with high-power desity and electric drives inspire design engineers to come up with more creative solutions. In many cases, they comprise small components with interfering contours, which pose new challenges for production. When hard finishing these gears, the process-related potential goes hand in hand with high production costs. The most economical option is probably generating grinding.
