FIELD: manufacture of abrasive tools. SUBSTANCE: fine grinding wheel is made with use of homogeneous nonwoven fibrous ruggerized disc formed by winding or drawing of several portions of fibers located on supporting means. Each next fiber portion is arranged at an angle to previous one to form fiber matrix in the form of zigzag with circular periphery. Fiber matrixes are cemented to form ruggerized disc. The device for manufacture of ruggerized disc has a supporting platform, many supplying spools with fiber, many clamps suitable for gripping of fiber ends with force sufficient for pulling of fiber from supplying spool and its tensioning along supporting platform. The device has a means for provision of adhesion of matrixes of discrete fibers. Nonwoven fine ruggerized grinding wheel has a central mounting hole and at least one nonwoven ruggerized disc with homogeneous configuration of fibers located from central mounting hole to circular periphery. Ruggerized disc is made in the form of several parallel installed fibrous matrixes. EFFECT: homogeneous efficient structure of strengthening of grinding wheel. 30 cl, 16 dwg, 1 tbl, 1 ex
