A method of making and the resulting non-metallic CMP conditioning pad comprising a non-metallic substrate and a single layer of abrasive particles bonded to the substrate by a non-metallic bonding medium. Preferred substrates include aluminum oxide and graphite. A bonding system employing finely powdered aluminum oxide particles mixed with a suitable adhesive is employed to bond the abrasive layer to the aluminum oxide substrate. Silicon carbide particles mixed into a compatible adhesive carrier including a polymer composition is preferred for bonding the abrasive particle layer to a graphite or carbide substrate.

A diamond hone for re-working and correcting lead and involute profile of hardened gears which is characterized by a monolayer of diamond abrasive bonded to a gear hone which is provided with a unique geometry wherein the tip and pitch diameter portions are specifically formed to obtain a predetermined deviation from the true involute form conventionally employed. This new diamond hone and unique geometry imparts the desirable final geometry in the re-worked gear.

A compression molding apparatus and method for the manufacture of abrasive layers for abrasive tooling which provides a compression mold space defined between an inflexible wall surface and a flexible wall surface. The apparatus and method of the present invention is particularly well suited to making annular or hollow cylindrical shaped abrasive layers of novel configurations during a single mold cycle useful for grinding wheel and the like, as well as other shapes such as laps, wherein the flexible wall expanded with fluid pressure provides a highly uniform distribution of pressure against the surface of the mold composition being formed. In an annular configuration, the flexible wall is used to radially direct pressure against a molding composition disposed in an annular configuration wherein the axial length of the annular mold shape formed may be many times greater than priorly obtained by the prior art means.
