How to achieve lower tolerances in production balancing machines

The ever increasing demands regarding reduction of noise, vibration and harshness (NVH) of machinery, power tools, household devices and rotating components in automotive applications require improved balancing accuracy and reduced balancing tolerances, among other manufacturing and design criteria, like reduction of audible bearing noise or air borne noise. This is true for rotors in various industrial applications like turbo machinery, and especially important for small armature electric motors, used in automotive applications. NVH requirements in the automotive industry are pushing the limits of technology. In recognising this need, we realized new technology and new techniques needed to be developed.
