摘要： The apparatus, for re-machining safety valves in situ on high pressure/high temperature plant and pipework, comprises a first gearbox and a second gearbox. The first gearbox has a first centre of rotation associated therewith and is configured to receive a driving torque. The second gearbox has a second centre of rotation associated therewith, is coupled to and is configured to be driven by the first gearbox. Coupling means is provided for transferring the drive torque from the first gearbox to the second gearbox. The coupling means is configured to define the location of the second centre of rotation relative to the first centre of rotation. A removable accessory assembly is provided and is coupled to the second gearbox, for carrying out a cutting, grinding or lapping operation to recondition a surface of a safety valve.
