About Balance Systems
At its headquarters in Pessano con Bornago near Milan, Balance Systems S.r.l. develops and manufactures balancing machines for rotationally symmetrical components as well as measuring and control systems for grinding machines. The product portfolio comprises manual, semi-automatic and fully automatic balancing machines – partly custom-built – as well as systems for automatic grinding wheel balancing (1 and 2 planes), touch detection (Gap & Crash) and in-process measurement. Components balanced include armatures for high-volume production, brushless motor rotors and rotating components for electric motors and UAVs/drones. The products are designed and developed entirely in Italy; services include remote service, spare parts supply and on-site support. Subsidiaries exist in France, the USA and Germany; the Chinese market is served through a dealer network.
