COOPERATION OF SPACE PRODUCTS WITH DETAILABLE SPACE HEADING

摘要

A cutting tool assembly (10) includes a support block (12), a replaceable spray nozzle housing, a liquid seal tight insert ring and first and second fluid passages. The first fluid and second fluid passage has an axis and extends between the concealable outer surface portion (22) and a first (20) surface portion of the support block. The first and second fluid passages are substantially straight between first and second outer surfaces so as to permit a drill to be inserted into first and second fluid passage for cleaning. The cutting tool assembly (10) also includes an exterior replaceable spray nozzle housing (14) on the support block having a cylindrical inlet portion (38) that extends into the first fluid passage such that the spray nozzle housing (14) is in fluid communication with the first fluid passage. A separate insert ring independent of a tool holding wear protective sleeve is press fit into the rear portion of the support block and forms an annular flow chamber section of the first fluid passage. The insert ring may be readily removed in the field to permit cleaning of the first fluid passage.
