ABSTRACT:
An adjustable cam is disclosed for use in grinding apparatus of the type where a cam pivots a part holder into and away from a grinding wheel. The adjustable cam consists of a central portion having two adjustable portions fixed at its ends such that the adjustable portions can be moved towards and away from a center position to result in a cam having a desired length. By selecting an adjustable portion having a desired width and radius and adjusting the distance between the two adjustable portions, a cam can be achieved that roughly corresponds to the final desired dimensions of the cam quickly and inexpensively. Some finish grinding may then be necessary in order to ensure that the final cam has the exact desired dimensions.
