PATENT 54,826 PD-9246 In a method for dressing a grinding wheel (2),by advancing a diamond nib (6) adjacent the outer circumference of the wheel (2) while the wheel (2) rotates about its axis, which method includes causing the diamond nib (6) to execute a plurality of passes in a direction parallel to the axis of wheel (2) rotation while displacing the nib (6) perpendicular to the axis of wheel (2) rotation in a pattern corresponding to the profile to be created at the wheel (2) circumference, which profile includes at least one annular groove having at least one side wall which extends in a given angular direction at an angle of no greater than 20.degree. to a plane perpendicular to the axis of wheel (2) rotation, the the wheel (2) is provided with a circumferential portion (14) which will not be used for a subsequent grinding operation and the nib (6) is driven in order to form, on the circumferential portion (14) an inclined surface (16) which extends in the given angular direction at an angle to a plane perpendicular to the axis of wheel (2) rotation which is greater than the angle of the at least one groove wall. |
