System for active control of auto excited vibrations in machine-tool, comprises spindle nut, which is arranged between nuts of displacement assembly, active actuator elements and sensors of mechanical tension

摘要

The system comprises a spindle nut, which is arranged between the nuts of displacement assembly, active actuator elements and sensors of mechanical tension. The sensor generates a response of variation of extension or strength between two active actuator elements depending on the strength of the nut to compensate the vibrations that affect the displacement assembly.
