Diamond Composites for Grinding Applications
Abstract
A significant portion on industrial activity is centered around component forming, starting from a blank or near net shape and then using appropriate material removal processes to finish them. Some of the basic material removal processes include cutting, turning, milling, boring, as well as the use of loose and bonded abrasives. Bonded abrasive tools are made in a variety of shapes, but most commonly appear in the form of integral or segmented wheels or cylinders or blocks. The abrasive sections of such tools are resin, glass or metal matrix composites that contain abrasive as a dispersed phase. The choice of abrasive is governed primarily by its wear resistance, toughness and relative hardness with respect to work material as well as economic considerations. The outstanding mechanical properties of diamond make it an excellent abrasive and the best choice for very demanding applications. In general, resin, glass and particularly metal bonded diamond abrasive composites represent the largest family of diamond composites. Using specific examples, the present paper reviews factors governing design of diamond composites for grinding applications.
