The present invention a jig assembly for clamping large size disc goods, comprising: a jig body installed on an upper surface of a working table of a machine tool, while a disc product in which a plurality of processing holes are formed is formed to be placed on the upper surface, in which a plurality of coupling groove are concavely formed on the upper surface on which the disc product is placed, while at least part of each coupling groove is disposed to be consistent with a region on which each processing hole of the disc product is formed; and clamping part which comprises a plurality of coupling members selectively coupled to each coupling groove by penetrating the processing hole of the disc product placed on the jig body, and a main clamping block rotatably installed to each coupling member in a horizontal direction, while pressing a non-processing region among the surface of the disc product by a coupling manipulation of the coupling member. Therefore, the main clamping part allows the clamping region of the large size disk product to be changed according to a processing region for the large size disc product. |
