Tooling for Controlled Grinding of an Edge To Remove Defects

A special-purpose grinding tool and fixtures have been developed for reworking an edge of a seal surface on a nozzle-throat-support housing in a rocket engine (see Figure 1) to remove defects caused by corrosion. Although the design of the tooling is specific to the original rocket-engine application, some aspects of the design may stimulate thinking about solutions to other special machining problems that cannot be solved readily by use of standard tooling alone.
