A rolling mill with high precision in which its rolls are automatically supported in two dimensions at their mid-portions for controlling their flexibility, comprising a housing, cluster of rolls and roll chocks. Said chocks consist of mid-chocks, side-chocks which are horizontally slidable an d middle supporting means therebetween. In order to minimize the flexible deflection of the rolls during rolling, the rolling mill of present inventio n is further provided with a bi-dimensionally mid-supporting automatic system, which is comprised of the housing, the chocks, a first mid-supporting means between the mid-chocks and the side-chocks, a second mid-supporting means between the housing and the chocks, a third mid-supporting means between the housing and the side-chocks. Said mid-supporting means comprises a screwdown means, horizontal supporting blocks, vertical supporting blocks and supporti ng blocks between the mid-chocks and the side-chocks. With such structure of th e rolling mill, the flexible deflection of the rolls is significantly suppressed, thereby reducing the deviation of the rolled strips or plates in the cross-sections.
