Title: Process and manufacturing of a rotary diamond dresser for trueing and dressing of industrial grinding wheels

Abstract: The invention applies to a diamond dresser consisting of a rotary symmetric body on whose circumference and/or face is applied randomly distributed diamond particles. It is the task of the invention to use simple means to reduce the abrasion on the circumference of the dresser, and thus to achieve a substantial increase in the operational life of the dresser. The invention holds that closely-spaced radial running grooves that stretch to the circumferential edge of one face of the dresser in which oblong diamonds are inserted and fastened, or that in the circumferential edge tightly-spaced radial recesses are formed into which oblong diamonds are inserted and fastened. These oblong diamonds are radially arranged and their ends protrude beyond the circumference of the rotary symmetric body. The oblong diamonds substantially reduce abrasion to the circumference of the rotary symmetric body. The oblong diamonds fit more closely into their metallic mount than do diamond particles, and because the oblong diamond mount is outside of the contact area of the abrasive grinding tool to be dressed and the dresser, and therefore the oblong metal bonding mount is better and more intensively cooled than the metal bonding the diamond particles themselves. Therefore, it is understandable that these oblong diamonds very effectively protect the otherwise earliest at worn circumferential area of the dresser from abrasion.
