METHOD AND DEVICE FOR VIBRATION CONTROL III

摘要

The invention relates to a device for vibration control in a machine for boring, the machine comprising a cutting tool (3) supported by a tool holder (5). The device comprises a control unit (33), a vibration sensor (29, 31) connectible to the control unit, and an actuator (25, 27) connectible to the control unit. The actuator comprises an active element (25, 27) which converts an A.C. voltage supplied by the control unit to the actuator into dimensional changes. The active element is adapted to be embedded in the body of the tool holder and is adapted to be embedded in such a manner that said dimensional changes impart turning moments to the body of the tool holder. The invention further relates to a method for vibration control in boring. The invention also relates to a tool holder (5) for boring.
