A grinding jig set comprising a combination of several jig units and a method for grinding a number of objects are provided. The method comprises a series of steps from arranging the objects to be ground on a grinding jig (a master plate) through removing the ground objects from the grinding jig after completion of grinding process, smoothly and precisely without damaging a number of the objects to be ground and without altering the arrangement pattern of the objects to be ground from the start through the end of the series of steps. The jig set for grinding comprises a set of jig units used for a series of processing from allocation of objects to be ground on a grinding jig through removing the ground objects from the grinding jig after the grinding operation. The jig units include a small allocation tray, a dividing tray which can transfer the objects to be ground retained in the small allocation tray from a starting tray to the small allocation tray, a dividing plate which can arrange the objects to be ground laid on the small allocation tray onto the surface of a grinding jig in the transferred state, and a removing tray onto which the ground objects removed from the surface of the grinding jig by a specified removing process can be relocated in the transferred state and divided into partial patterns.
