When rolls (5) in a rolling mill are repaired, a roll stand (2) is first dismounted from the rolling mill. Then the dismounted roll stand is secured and the rolls are pressed against the housing (4) of the roll stand in the axial direction of the roll for eliminating of the clearance. In this situation the rolls are cut. After the rolls have been cut, the roll stand is released from being secured. Then the roll stand is mounted on the rolling mill. A cutting apparatus used for cutting rolls comprises a base frame (32) and a stand (33) mounted on the base frame for placing the roll stand (2) thereon. The housing (4) of the roll stand placed on the stand is secured against the base frame. Furthermore, the rolls (5) of the roll stand are brought near to the housing in the axial direction of the roll and are located. In the situation located against the housing, the rolls are rotated by a roll rotating apparatus (38) and cut with a cutting tool (90).
