For micro drilling, it has been said that application of ultrasonic vibration can help the precision and efficiency of it. Many types of ultrasonically assisted drilling have been researched and developed. In the developments, piezoelectric ultrasonic transducers are installed in spindles. Therefore, they need mechanism like slip rings to provide driving electric energy to the transducers. On the other hand, the spindle is needed to turn at high speed. Contact elements, such as the slip ring, avoids the high speed operation. To solve the problem, we propose non-contact vibration transmission through air gap. The transmitted vibration direction can be converted by a vibration direction converter. This paper describes the development of the converter and vibration transmission through the air gap. Experimental results to evaluate the feasibility of our method is also reported.
