5. A dressing bar assembly for a cylindrical grinding machine comprising
a base including a bore, a sleeve member matingly inserted into said base bore, said sleeve member being axially truncated and having an axially extending slot opening along the truncated surface, means for securing said sleeve member at a predetermined axial and radial location, an abrasive block located within said slot and projecting beyond said slot opening, retainer means located with said sleeve member within said base bore and including an abrasive block engaging surface, means for maintaining said retaining means at a predetermined axial location within said bore, means for forcefully urging said retainer means against the axially exposed portion of said abrasive block to frictionally hold said abrasive block in its axial position, means for retracting said retainer to free said abrasive block, and means for overcoming said frictional engagement and axially advancing said abrasive block.
