More sophisticated technical developments lead to constantly increasing requirements with regard to balancing quality. The trend is clear: Higher performance is achieved first of all by higher speeds. Examples are high-speed tool spindles, electric motors, turbines, fans, universal joint shafts or paper rolls. You certainly see this trend in your branch, too. In fact, it is by balancing that such developments have become possible. Accurately balanced rotors allow a considerably higher performance-without any negative effect on the environment.
