A grinding wheel and a method for grinding bar blade for the production of spiral gear teeth are described. For economical grinding of such bar blades the grinding wheel has a conical grinding surface (Pp) widening from a small diameter (d1) to a large diameter (d2), a cylindrical grinding surface (Ps) adjoining the conical grinding surface (Pp), and a toroidal grinding surface (G) adjoining the cylindrical grinding surface (Ps). The grinding wheel embodied in this manner enables profile grinding (rough grinding) and subsequent generating grinding (finish grinding) of the surfaces of the bar blade without the necessity of remounting the blade. For practical purposes the grinding wheel rotates about a stationary axis (S), and the bar blade to be ground is guided along the grinding wheel at appropriately set angles.
