Abstract
A tool sharpening or finishing machine is provided having an improved, low cost, laterally shiftable and tiltable tool-supporting table adjacent a rotatable, abrasive wheel. The table is supported for back-and-forth shifting by a roller bearing assembly having a plurality of spaced apart and resiliently biased together bearings connected to a base, with a shiftable element received between the bearings and connected to the table. The base is preferably slotted between the spaced bearings to form a structural spring within the base, and one of the bearings is eccentrically mounted for selective variation of the effective distance between the bearings, so that the bearing assembly can be properly preloaded without the need for precision manufacture of the assembly components. The table is supported for tilting movement relative to the grinding wheel surface by means of an upright, pivotal plate which has an associated spring-loaded counterbalancing mechanism urging the table upwardly and permitting accurate table settings.
