Abstract
Abstract A device for dressing abrasive wheels, whose essence resides in making the working zone free with a view to utilizing large diameter abrasive wheels and working large-sized articles, characterized by the provision of vertical guide members in a member that carries an abrasive wheel, whereby the holder of a dressing tool, which travels along a guide member inclined at an angle of 45* to the horizon, moves the abrasive wheel towards the article being worked.
