Abstract:
A device for centering a circular cutting tool on a machine, the tool having a bore, the device comprising:a mounting plate adapted to be attached to the machine to support the tool and to present the tool to a processing element;first and second bearings on the plate; anda third bearing mounted for movement on the plate selectively toward and away from the first and second bearings so that the first, second and third bearings are engagable with the bore of the tool and the tool is centered on the machine when the third bearing is moved from the first and second bearing securely pulling the tool bore against the first and second bearing, whereby the tool is then rotatable about its center axis, wherein the third bearing is selectively movable toward and away from the first and second bearing along a line which is at an angle relative to a first reference line which is perpendicular to a common centerline through the axes of the first and second bearings.
