Abrasive pad assembly

Abstract

An abrasive pad assembly, for use with a surfacing machine, includes a circular pad member and a diamond abrasive member. The circular pad member includes an exterior surface and the diamond abrasive member is affixed to the exterior surface of the circular pad member. The diamond abrasive member includes an insert and a diamond abrasive material. The insert has a first surface affixed to the exterior surface of the circular pad member. The diamond abrasive material is a polycrystalline diamond substance that is affixed to the second surface of the insert. The polycrystalline diamond material is spaced apart from the exterior surface of the circular pad member.
