Rotary imbalance reduction device, for high-speed machine tool, uses imbalance correction masses adjusted via piezoelectric setting elements

摘要

The device (10) uses an imbalance correction mass (11) at least partially enclosing a drive shaft (12) coaxial to the rotation axis and adjusted radially relative to the drive shaft via at least 2 piezoelectric setting elements (20). An Independent claim for a method for reducing the rotary imbalance in a high-speed machine tool is also included.
