A supporting disk for a surface grinding wheel with laminas, the supporting disk consisting of
- a glass-fiber reinforced phenolic resin body, which includes
- an upper covering layer (6) of a textile glass fabric (9);
- an intermediate layer (7) of a fiber fleece;
- and
- a lower covering layer (8) of a textile glass fabric (9) and
- wherein the upper covering layer (6) and the lower covering layer (8) have a higher tensile strength than the intermediate layer (7).
A surface grinding wheel comprising a supporting disk (1) and abrasive laminas (2) fixed to the supporting disk (1), the supporting disk (1) consisting of
