Abstract: A steel strip grinding machine for the continuous grinding of the upper and lower surfaces of steel strips includes a pair of vertically displaceable spindles into which the grinding rolls are journalled. One of the spindles is slidable axially whereas the other spindle is fixedly secured in the machine frame. The grinding rolls are thus removable through sliding of the axially slidable spindle without having to disassemble any bearings. The lower grinding roll is supportable on a lift truck mechanism for movement in and out of the machine frame whereby removal of such grinding roll for the lower surface of the steel strip can be effectuated without use of a crane. Further, a device for dressing the outer peripheral surface of the grinding roll is provided adjacently to the grinding roll. The grinding roll is made by spraying a thermosetting resin containing hone grains upon a nonwoven fabric in which filaments are entangled at random. Its shaft is formed to be hollow.
