ABSTRACT:
An abrasive pad having dots of abrasive material disposed thereon includes a central alignment hole. The abrasive pad is formed by slipping a backing pad having a central alignment hole onto an alignment stud that extends from a support surface through the central alignment hole. A mold having a plurality of fill holes and an alignment hole is then placed against the backing pad such that a portion of the alignment stud extends into the mold alignment hole. A mixture of abrasive material is deposited into the fill holes. Heat is applied and the mold is removed. The abrasive material is allowed to cure to create an abrasive pad having abrasive dots.
