Title:
TOOL FOR MACHINING A CMC BY MILLING AND ULTRASONIC ABRASION
Document Type and Number:
WIPO Patent Application WO/2011/020775
Kind Code:
A1
Abstract:
The invention relates to a tool for machining hard materials such as metal-matrix or organic-matrix composite materials, comprising a cylindrical sonotrode (22) connected, along the axis (A) of said cylinder, to an assembly vibrating at a predetermined ultrasonic frequency and rotated about said axis, and at least one nozzle (3), on the surface to be machined and at the terminal end (24) of the sonotrode, for ejecting a liquid in which abrasive particles are suspended, said particles being vibrated at said ultrasonic frequency by the sonotrode so as to form a drilling head along the axis (A) of the cylinder, characterized in that the circumference (23) of the sonotrode is covered with particles of a so-called superhard material in order to form a milling head capable of moving in a plane that is substantially perpendicular to said vibratory axis (A).
