Patent ID: 8905689

Claim:
A machining system, comprising: (a) an ultrasonic machining assembly, wherein the ultrasonic machining assembly further includes: (i) a machining tool; (ii) a collet adapted to receive the machining tool, wherein the collet further includes: a) a first or upper portion defining a chamber therein; b) a second or lower portion, wherein the lower portion further includes an outer shell wall, an inner chamber defined by the outer shell wall, and a cylindrical extension formed in the inner chamber; c) a rigid nodal point mounting ring formed between the upper and lower portions; and d) a circumferential undercut formed in the outer shell wall of the lower portion directly beneath the rigid nodal point mounting ring; and (iii) an ultrasonic transducer, wherein the ultrasonic transducer is operative to transmit acoustical vibrations to the machining tool; and (b) a machining apparatus, wherein the machining apparatus is adapted to receive the ultrasonic machining assembly, and wherein the machining apparatus is operative to transmit torque to the machining tool by applying rotary motion to the ultrasonic machining assembly.
