Abstract: The apparatus includes a frame and a holder rotatably secured to the frame for releasably holding a first workpiece of the workpieces. A mechanism is provided for rotating the holder from a loading station to a grinding station and a grinder is movably secured to the frame and selectively positionable relative to the first workpiece when the first workpiece is located at the grinding station. A control is included for selectively positioning the grinding means relative to the first workpiece for grinding the first workpiece and a further holder is rigidly secured to and spaced relative to the holder. The arrangement is such that when the holder is rotated in a direction towards the grinding station, the further holder is rotated in a direction towards the loading station for loading a second workpiece of the workpieces at the loading station so that sequential grinding and loading of the workpieces is permitted.
