ABSTRACT:
An apparatus for the precision grinding of conical valve seats of nozzles, for example, injection nozzles for internal combustion engines. The body is entered hydraulically on a mandrel and a driver has a rubber O-ring braced against the nozzle body to frictionally engage it is rotation while passing through the mandrel for the shaft of a grinding tool which is located at the end of the mandrel. The system avoids radial clamping stresses on the workpiece and hence allows, precision low tolerance finish grinding to be achieved.
