Anordning och metod för styrning av vibrationer samt verktygshållare

摘要

The invention relates to a device for vibration control in a machine for cutting, said machine comprising a cutting tool supported by a tool holder. The device comprises a control unit and converting means which are connectible to the control unit and comprise a vibration sensor and an actuator. The actuator comprises an active element which converts an A.C. voltage supplied by the control unit to the actuator into dimensional changes. Said active element is adapted to be embedded in the body of the tool holder and in such 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 cutting. The invention also relates to a tool holder.
