DRESSING DEVICE FOR THE DRESSING OF PROFILE GRINDING WHEELS

摘要

Dressing device for a form or profile grinding wheel. Two quills, each carrying a dressing tool at its respective end, are positioned coaxially within a sleeve and arranged with the respective dressing tools pointing in opposite directions. Means are provided for adjusting each quill independently of the other axially but nonrotatably. Each quill comprises a bearing for the other within said sleeve and the whole is arranged for arcuate movement about an axis perpendicular to the grinding wheel axis so that one quill can work on one grinding face of the wheel and thereafter the other quill can work on the other grinding face of the grinding wheel.
