New information has been obtained on the effect of ultrasonic radiation on metal wire drawing. Wire drawing operations have been significantly improved by design modification of die holder assembly and transducer-horn mounting. A major contribution was made by the development of an isolator positioned between die and draw chuck. Tungsten carbide dies have been adapted and considerable improvement has resulted in surface finish. Author
