Description: Diamond Grit Impregnated Dressers have been developed from multi-point dressers. The diamond grit impregnated dressers are manufactured from diamond grit rather than a larger number of small natural diamonds. The advantages of the diamond impregnated dresser lie in its exceptional sharpness, which results from sharp edges and points of the diamond grit. These dresser are used in applications like dressing resin, vitreous and rubber bond, fine grit and even 'grit free' grinding wheels, as well as boron carbide grinding wheels, dressing single profile threaded,V-profile grinding wheels, for general dressing operations on centreless, cylindrical and surface grinding machines. Dressing time is reduced as higher feed rates can be used. There are an unlimited number of sharp pull-out-free cutting edges contained in the crushed diamond grit. The dressers demand greater care in selecting the correct dresser for a given application. The bond and diamond grit size used are both variable according to the type of grinding wheels to be dressed. The size of the diamond grit particles should be matched to the grit size of the grinding wheel. While using this diamond grit dresser, normal dressing speeds should be maintained and a plentiful supply of coolant should be provided both before and during dressing to prolong dresser life. The diamond grit impregnated cutting face of the dresser should be set at an angle of 90? to the grinding wheel to be dressed, so that all the cutting edges of the diamonds grit are able to make contact with the wheel face. The feed rates used may be double of those used with single-point diamond dressers. The depth of cut should be approximately 0.01 mm and the rough grinding should be approximately 0.02 mm.
