Abstract
A device for establishing the initial distance between the surface of a grinding tool and the surface of a workpiece to be ground. A combination of an active and a passive sensing element rigidly connected at a known distance is positioned between the workpiece and the grinding tool. The workpiece is brought into contact with the passive sensing element and both the workpiece and sensing elements are moved toward the grinding tool while maintaining contact. The active sensing element senses the grinding tool when the distance between the tool and the workpiece is equal to the distance between the active and passive sensing elements. When this occurs, the active sensing element provides a signal and therefore the distance at which the grinding wheel will meet the workpiece can be calculated. A fixed abutment is also provided so that absolute measurements of the dimensions of the workpiece or grinding tool can be obtained.
