A medical instrument and method for producing a medical instrument with at least one instrument body part made from an instrument body part blank by forming. The at least one instrument body part has at least one deburring face formed by milling. The at least one deburring face includes one or more portions. Each portion extends perpendicularly to a machining plane. A normal to the machining plane defines a deburring longitudinal axis.

An ultrasonic vibration assisted machining device is applied to a cutting tool and includes a vibrating component and a spinning component. The vibrating component includes a main body including a first end surface, a second end surface and a central axis. The vibrating component is configured to receive electrical power and generate a vibration with a vibrating frequency in the central axis direction according to the electrical power. The spinning component includes a first surface connected to the second end surface of the vibrating component. The area of the first surface is greater than that of the second end surface. The spinning component generates a spinning motion centered on the central axis according to the vibration with the vibrating frequency generated by the vibrating component. Wherein, the spinning component transmits the vibration and the spinning motion to the cutting tool.
