ABSTRACT:
A separator is placed between the mold, and a body of matrix material with hard particles being compacted, for forming an abrasive body. The separator may be relatively soft, so some of the hard particles will partially enter the separator during compaction. Subsequent removal of the separator leaves particles protruding through the retaining surface so the abrasive body does not necessarily require dressing. The separator may act as a release agent to facilitate removal of the abrasive body. The separator may also be contoured so the abrasive body will be contoured after compaction. A plurality of separators may be used to provide different functions simultaneously.
