ABSTRACT:
An efficient method for manufacturing bonded abrasive articles comprises the use of elongated abrasive grain having a length to cross-sectional width aspect ratio of at least 5:1 to yield abrasive articles which are highly permeable to the passage of fluids. A method for measuring permeability is provided. The abrasive articles are used to carry out soft grinding and deep cut grinding operations. The permeable abrasive articles provide an open structure of pores and channels permitting the passage of fluid through the abrasive article and the removal of swarf from the workpiece during grinding operations.
