The design of grinding wheel balancing control system and control software

In order to reduce the unbalance of grinding wheel influence on machining accuracy and the life of grinding machine, a new grinding wheel dynamic balancing control system has been designed, it contains hardware and software part of the system. The system is based on ARM (STM32F417) as the core processor, it consists of the vibration measurement module, rotational speed measurement module, signal processing module, balancing control module and so on. The system can real-time monitor the unbalance through piezoelectric sensor when grinding wheel is rotating, then the drive control circuit of control card controls two eccentric gears rotate in balance head to achieve grinding wheel balancing. The system has high efficiency and can improve machining accuracy of grinder.
