Prior art dressing tools have not been able to provide both free cutting and smooth surface finish. Dressing tool (10) does this by incorporating two abrasive members (16) and (18), one of which (16) is positioned to crush when the tool is applied to a rotating grinding wheel, while the other (18) shears the wheel. Preferably one abrasive member (16) contacts the grinding wheel tangentially, the other member (18) being placed normal to the grinding wheel at a rake angle ranging from positive to negative. <IMAGE> |
