Abstract
A wire for machining with the aid of an abrasive comprises a core wire of a hard metallic material and wrapped therearound in an open helical configuration a band of a softer material which is sufficiently soft for the surface thereof to be impregnated with a subdivided abrasive material. Apparatus for machining a work piece constituted of a hard material by contacting the material with a moving wire, which may, for example, be the aforementioned wire, comprises means for holding the work piece in contact with the wire while, simultaneously, transmitting ultrasonic energy into the wire, vibrating the wire at frequencies lower than ultrasonic and reciprocating the wire lengthwise.
