The present invention relates to an apparatus for grinding. According to the first embodiment of the present invention, the apparatus for grinding comprises: a base plate; a rotating support unit installed on the top of the base plate to be able to rotate and to fixate an object to be processed; a driving unit connected to one side of the rotating support unit to provide a rotation driving force to the rotating support unit; multiple guide axes installed vertically on the base plate to surround the rotating supporting unit, with a thread of a screw formed on the outer circumferential surface; multiple elastic support units inserted into each of the multiple guide axes and installed for its one end to contact the base plate, which have elasticity; multiple elasticity control units combined with each of the multiple guide axes with a screw to move up and down following the thread of the screw when rotating around the axis of each of the multiple guide axes and to compress or recover each of the multiple elastic support units; and, a grinding unit installed in between the multiple elasticity control units and the multiple elastic support units to receive an elastic support from the multiple elastic support units compressed or recovered by the multiple elasticity control units, which comprises a grinding member for grinding the object to be processed by contacting the object to be processed. |
