Embedded damping vibration attenuation turning tool holder for deep cavity machining and method

An embedded damping vibration attenuation turning tool holder for deep cavity machining and a method includes a tool holder and a damper; one end of the tool holder is connected with a turning blade; a side surface of the tool holder is provided with a square cavity; the damper is in interference fit in the square cavity; the damper includes a mass block, an elastic member and piezoelectric ceramic; at least one surface of the mass block that is in contact with an inner wall of the square cavity is connected with the piezoelectric ceramic; the elastic member is arranged between the piezoelectric ceramic and the mass block; and the piezoelectric ceramic is used for generating interaction with the inner wall of the square cavity under a vibration action of the tool holder, so as to absorb the vibration to generate electric energy.
