ABSTRACT:
A portable orbiting grinding machine to grind the gas check seat on 155 mm un tubes. The critical sealing surface is ground concentric with the chamber diameter. Instead of moving the gun tube to a specified machine tool, the portable grinding machine can be loaded on a specified tube for grinding the gas check seat then moved to the next tube to start the sequence again. A hydraulically expanded arbor grips the gun tube chamber diameter. An orbital spur gear assembly rotates on the expanding arbor extension and has a longitudinal travel on the extension controlled by a feed mechanism assembly. A removeable grinding quill is held by the spur gear assembly as it rotates. A sleeve type grinding wheel dresser assembly has a blade that may be mechanically actuated to bear against the grinding wheel and is spring loaded away from the grinding wheel when not in use.
