Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 55 words
A heavy duty grinding wheel in which abrasive grits are bonded in a resin matrix, characterized in that the abrasive grits are a 3:1 to 1:3 by volume mix of spherical sintered bauxite abrasive particles having a Krumbein No. of at least 0.8 and non-spherical abrasive particles having a Krumbein No. of 0.4 or less.
Claim 2
Dependent Claim 55 words
A heavy duty grinding wheel in which abrasive grits are bonded in a resin matrix, characterized in that the abrasive grits are a 3:1 to 1:3 by volume mix of spherical sintered bauxite abrasive particles having a Krumbein No. of at least 0.8 and non-spherical abrasive particles having a Krumbein No. of 0.4 or less.
Claim 3
Dependent Claim 15 words
A grinding wheel according to claim 1, in which the non-spherical particles are fused alumina-zirconia.
Claim 4
Dependent Claim 29 words
A grinding wheel according to claim 1, in which the non-spherical particles are rod-shaped sintered bauxite particles having a length to diameter ratio average greater than 1.4 to 1.
