Improvement relating to cutting. |
摘要 |
<p>A cutting device comprises an ultrasonic horn (6) comprising a cylindrical body portion (8) having a face to which longitudinal ultrasonic vibrations are applied by a piezo-electric transducer (12) through a booster (14). On the opposite side to the face (10) the body (8) is outwardly flared into a bell-shaped section (16), terminating in a circumferential flange (18). The flange (18) may be provided by a cutting edge, which in the operation of the device undergoes a "pulsating" motion, vibrating alternatively radially outwardly in an expansion mode and radially inwardly in a contraction mode. Preferably however one or more cutting blades (24) are attached to the flange (18), to effect cutting. Conveniently the device comprises means (22) to enable the cutting device to be attached to a rotary mandrel or spindle, to enable the cutting device to be rotated about its longitudinal axis. <IMAGE></p> |
