摘要： A composite focus tube for a cutting head of an abrasive waterjet cutting machine includes a chemical vapor deposition diamond (CVDD) tube retained within a holder. The CVDD tube is held within a passage extending through the holder by filling the volume between walls of the CVDD tube and walls of the passage with a polymer, ideally an adhesive, or with a low-melting point metal or alloy, which support and hold the CVDD tube in position without exerting significant stress on it. A longitudinal axis of a through bore of the CVDD tube coincides with a centerline of the holder to allow precise location and alignment of an abrasive waterjet emitted from the CVDD tube. The CVDD tube has a rough, faceted outer surface and may have a variable wall thickness. The holder may comprise the body of the cutting head.

摘要翻译： 用于磨料水射流切割机的切割头的复合聚焦管包括保留在保持器内的化学气相沉积金刚石（CVDD）管。 CVDD管被保持在延伸穿过保持器的通道内，通过用聚合物（理想地是粘合剂）填充CVDD管的壁和通道的壁之间的体积，或者与支撑和保持的低熔点金属或合金 CVDD管的位置不会对其施加显着的应力。 CVDD管的通孔的纵向轴线与保持器的中心线重合，以允许从CVDD管发射的磨料水射流的精确位置和对准。 CVDD管具有粗糙的多面外表面，并且可具有可变的壁厚。 保持器可以包括切割头的主体。
