Cutting tool and cutting machine

A cutting machine comprising a bearing, a rotary shaft rotatably mounted to the bearing, a cutting tool which comprises a cutting disc blade having a center hole and a ultrasonic transducer in the form of ring which is coaxially fixed at least onto one surface of the disc blade and which is mounted around the rotary shaft, and a power source electrically connected to the ultrasonic transducer.

A cutting machine comprising a bearing, a rotary shaft having a pair of radially extended flanges which is rotatably mounted to the bearing, a cutting tool which comprises a cutting disc blade having a center hole and a ultrasonic transducer in the form of ring which is coaxially fixed onto each surface of the disc blade via rigid material layer in the form of ring under such condition that an outer periphery of the rigid material layer extends over an outer periphery of the ultrasonic transducer and which is mounted around the rotary shaft under such condition that the cutting tool is supported by the pair of radially extended flanges at an outer peripheral area of the rigid material layer, and a power source electrically connected to the ultrasonic transducer.
