Apparatus for performing machining operations on a workpiece or detail at different angles, comprising a rotatable table having a plurality of locating holes preferably spaced at one degree intervals about its periphery, two indexing pins insertable in the holes, and two indexing blocks having prongs provided with abutment surfaces in positions to be contacted by the pins. The table normally rests upon pads during a machining operation. To rotate the table to a new position, the table is lifted from the pads by a manually operable lifting mechanism. Anti-friction rollers support the table when raised to facilitate rotation.
