Abstract
A disc-shaped, rotary dressing tool has a rigid core and an abrasive rim around at least one surface of the periphery of the rigid core. The rigid core and the abrasive rim are oriented in a direction orthogonal to the axis of rotation of the tool. In an embodiment, the abrasive rim comprises an abrasive component bonded to the rigid core by means of an active braze. The abrasive component can be diamond grains arranged in a single layer or diamond film inserts. In a particular embodiment, the abrasive component can comprise a plurality of abrasive inserts mechanically fastened to the rigid core. In another embodiment, the abrasive rim can comprise strips of an abrasive component with each strip being filled into slots machined into and through the perimeter of the core.
