In a method of dressing a grinding wheel 14 to form thereon a peripheral surface of a required cross-sectional profile, the grinding wheel is rotated at a predetermined speed, and rotated about a parallel axis is a dressing wheel (10) having a hard peripheral forming surface the cross-sectional profile of which is the complementary inverse of said required cross-section profile. The peripheral surface of the grinding wheel 14 is brought into pressing engagement with the peripheral surface of the dressing wheel 10, and while maintaining the pressing engagement the speed of rotation of the dressing wheel is controlled in a manner to provide a difference in speed between the engaging peripheral surfaces. The speed of rotation may be controlled by direct control of an electric servo-motor 12 driving the dressing wheel 10, or by controlled braking of the dressing wheel. For a given composition of grinding wheel and dressing wheel the surface characteristics of the finished wheel may thus be determined in a predictable fashion by pre-setting an appropriate predetermined speed of rotation for the dressing wheel.
