Method of determining the number of active diamonds on a conditioning disk

A method for determining the number of active diamonds on a diamond conditioner disk, comprising:

• (a) contacting a diamond conditioner disk with a hard surface, wherein the diamond-containing side of the diamond conditioning disk is facing the hard surface,
• (b) moving the diamond conditioner disk under a load across the hard surface so as to cause an active diamonds present on the diamond-containing side of the diamond conditioner disk to leave a mark corresponding to each active diamond, and
• (c) counting the marks to determine the number of active diamonds on the diamond conditioner disk,
• wherein the hard surface further comprises a layer of contrasting material such that when the diamond conditioner disk moves across the hard surface, the diamond conditioner disk passes the layer entirely from one end to the other and scratches the layer of contrasting material on the hard surface thereby leaving a mark.

A method for determining the number of active diamonds on a diamond conditioner disk, comprising:

• (a) contacting a diamond conditioner disk with a hard surface wherein the diamond-containing side of the diamond conditioning disk is facing the hard surface,
• (b) moving the diamond conditioner disk under a load across the hard surface so as to cause any active diamonds present on the diamond-containing side of the diamond conditioner disk to leave a mark corresponding to each active diamond, and
• (c) counting the marks to determine the number of active diamonds on the diamond conditioner disk,
• wherein the marks are counted using a profilometer.

• (b) moving the diamond conditioner disk under a load across the hard surface so as to cause any active diamonds present on the diamond-containing side of the diamond conditioner disk to leave a mark corresponding to each active diamond, and
• (c) counting the marks to determine the number of active diamonds on the diamond conditioner disk,
• wherein the marks are counted using an optical microscope.

A method for determining the number of active diamonds on a diamond conditioner disk, comprising:

• (a) contacting a diamond conditioner disk with a hard surface, wherein the diamond-containing side of the diamond conditioning disk is facing the hard surface,
• (b) moving the diamond conditioner disk under a load across the hard surface so as to cause any active diamonds present on the diamond-containing side of the diamond conditioner disk to leave a mark corresponding to each active diamond, and
• (c) counting the marks to determine the number of active diamonds on the diamond conditioner disk,
• wherein the hard surface is a rectangular polycarbonate sheet that is clamped to a flat work surface, the hard surface further comprising a layer of contrasting material consisting of a band of constant width applied by marking the hard surface with an indelible felt tipped marker across the upper surface of the polycarbonate sheet perpendicular to the longer axis of the polycarbonate sheet, and wherein the diamond conditioner disk contacts the hard surface such that the lead edge of the disk is at or near the beginning of the band, and wherein the diamond conditioner disk is moved at a constant velocity parallel to the longer axis of the polycarbonate sheet so that the diamond-containing surface of the disk completely passes over the felt marker band.
