According to the blade milling and strengthening ultrasonic device and the machining method, a blade clamping and rotating mechanism drives a blade to rotate, an X-axis moving mechanism drives the blade clamping and rotating mechanism to move along the X axis, and a Y-axis moving mechanism and a Z-axis moving mechanism drive a spiral vibration ultrasonic mechanism to move in the YZ plane; the spindle rotating motor drives the tool to rotate, the transducer drives the tool to longitudinally vibrate, the spiral groove is arranged, so that the tool can longitudinally vibrate and simultaneously do reciprocating torsional vibration, namely, the longitudinal vibration and the reciprocating torsional vibration are superposed to form reciprocating spiral vibration, and the reciprocating torsional vibration is used for assisting milling. The surfaces of the blades are smoother; longitudinal vibration impacts the surface of the blade, and residual compressive stress is given to the surface of the blade to achieve surfa
