Device which can be fitted onto machine tools such as lathes used for the manufacture of nuts.

摘要

The device is noteworthy in that the tools for drilling, cutting, chamfering, and traversing working axially and/or perpendicularly to the bar to be machined, are simultaneously or successively subjected, independently of their cutting trajectory and of their function, to a vibratory ultrasound field created by one of more generators and transmitted by transducers arranged in the extension of each tool. <IMAGE>
