Abstract

A device for determining the coefficient of friction of diamond conditioner discs and a method of use thereof. The device is a solid base means comprising a block of granite with a smooth flat upper surface, a diamond conditioner disc counter surface means comprising a removable sheet of polycarbonate, a means for moving the diamond conditioner disc comprising an assembly parallel to and perpendicular to the surface of the said slab and overlain material along which a plate, the surface of which is parallel to the surface of the assembly and perpendicular to the surface of the said slab and overlain material, is moved by a screw, a means for securing the diamond conditioner disc comprising a holder bolted to the said plate that is capable of riding just above the surface of the slab and overlain material with an anterior face with respect to the direction of motion that is concave and capable of securely holding a diamond conditioner disc placed grinding face down upon the said overlain material the top of which is open so that load may be applied to the diamond conditioner disc and a means for measuring the shear force imparted by the moving diamond conditioner disc comprising a load cell. Shear force and down force are determined using the above apparatus and the coefficient of friction of the diamond conditioner disc and the said sheet are calculated therefrom.
