Abstract
A segmental grinding wheel includes abutting, interfitting and interchangeable composite abrading segments clamped to a rotary chuck, each of which comprises a preformed bonded abrasive segment of simple shape with at least a portion of each side, except a working face thereof, encased in a relatively non-abrasive precision molded plastic shell of precise dimensions, more complex and perfect interfitting configuration. The shell is preferably made of material that is or contains a grinding aid, prevents coolant swarf from filling the pores of the abrasive segment and reinforces the abrasive segment.
