1. A balancing system for a rotating spindle of a machine tool, the balancing system comprising:
a rotating part connected to the spindle, the rotating part comprising:
at least one balancing head comprising:
at least one balancing mass eccentrically arranged with respect to a rotation axis, and
at least one electric motor configured to adjust the position of the balancing mass;
at least one vibration sensor; and
a control system comprising at least one processor and at least one memory storing software configured to be executed by the at least one processor;
a stationary part comprising processing and control electronics; and
a wireless communication system configured to establish communication between the control system and the processing and control electronics,
wherein the software stored on the at least one memory of the control system comprises:
a management application that, when executed by the at least one processor, is configured to manage the balancing head and the vibration sensor; and
a service application that, when executed by the at least one processor, is the only application started after the control system is powered on, and is configured to automatically not start the management application, receive code packets corresponding to an updated version of the management application from the processing and control electronics through the wireless communication system, and overwrite the existing version of the management application with the updated version of the management application.
