A grinding apparatus of a plasma display panel is provided to transfer a grinder to a corresponding position prior to a grinding process of a substrate, thereby reducing a time required to align the substrate with the grinder. A grinding apparatus includes a position detecting unit(46) detecting a position of a substrate, a grinder(50) grinding the substrate corresponding to the position detected by the position detecting unit, and a grinder transferring unit(48) transferring the grinder to the position detected by the position detecting unit. The substrate is supported by a substrate supporting part(42). A transfer unit(40) transfers the substrate to the substrate support part and transfers the substrate support part to the detected position.
