Abstract

본 발명은 연삭재혼입 워터제트 절삭장치의 2부재 구성의 것의 내균열성의 워터제트 혼합튜브 및 그것의 준비방법에 관한 것이다. 이 방법은 깔때기형상 지지부재상에 다이아몬드 층을 화학증착하여 상기 혼합튜브의 내측부재를 형성하는 것과, 상기 지지부재로부터 상기 내측부재를 분리하는 것과, 상기 내측부재의 외측면상에 외측부재를 용착한 다음 냉각하여 상기 내측부재상의 균열발생을 사실상 방지하는 압축응력을 상기 내측부재상에 형성하는 것을 포함한다. 상기 내측부재의 내측면은 미정질 구조의 평활한 구멍을 가지면 외측부재는 다이아몬드보다 열팽창율이 크다.
또한, 본 발명은 상술한 거의 내균열성의 개선된 워터제트 혼합튜브를 갖는 워터제트 절삭장치에 관한 것이기도 하다.
