Large Diameter Cutting Tool
First Claim
1. An abrasive cutting tool, comprising:
- a body in a shape of a large diameter disk having an outer diameter of at least about 60 centimeters, and an aspect ratio defined as a ratio (D;
T) between the outer diameter to an axial thickness of the body of at least about 10;
1, and the body including an abrasive portion having;
a bond material;
abrasive particles contained within the bond material;
a first filler contained within the abrasive portion comprising iron and sulfur having an average particle size of not greater than about 40 microns;
wherein the body further comprises a reinforcing member; and
a Thermal Adhesion Factor (TAF) of at least about 30%.

Abstract
An abrasive cutting tool includes a body in a shape of a large diameter disk having an outer diameter of at least about 60 centimeters. The body has an aspect ratio defined as a ratio (D:T) between the outer diameter to an axial thickness of the body of at least about 10:1. The body includes an abrasive portion having a bond material and abrasive particles contained within the bond material. The abrasive portion also includes a first filler having iron and sulfur with an average particle size of not greater than about 40 microns. The body also includes a reinforcing member and a Thermal Adhesion Factor (TAF) of at least about 30%.

61. An abrasive cutting tool, comprising:
-
a body in a shape of a large diameter disk having an outer diameter of at least about 60 centimeters, the body also having an aspect ratio defined as a ratio between diameter to thickness of at least about 10;
1, and the body including an abrasive portion having;a bond material; abrasive particles contained within the bond material; wherein the body comprises a CVR index of at least about 1% greater than a body of a conventional abrasive cutting tool, wherein the CVR Index comprises [(CVR1−
CVR2)/CVR1]×
100%, wherein CVR1 is a CVR surface coverage of the body, and CVR2 is a CVR surface coverage of the body of the conventional abrasive cutting tool; andthe body has a Thermal Adhesion Factor (TAF) of at least about 30%.
