| 摘要 |
The ultrasonic device comprises a generator (8) supplying at least one transducer (9-10) mounted on a movable element of a machine (1), attached to a cutter (5); the transducers (9-10) generate an oscillation in the cutter (5) which causes a sustained ultrasonic vibratory phenomenon allowing the cutting forces to be decreased during machining. <IMAGE>
