Abstract
A device for setting cutters in the periphery of an annular cutter holder to a plurality of selected radii, said device including a base for rotatably supporting the cutter holder and an adjustable gauge mounted on said base which may be selectively positioned at a plurality of settings to provide a plurality of distances to which cutters may be set from the center of the cutter holder, said cutter holder having one or more angular shaped slots in the underside thereof for receiving cutters therein and wedge means for securing the cutters in said slots.
Claims7
A device for setting cutter blades at predetermined positions in the periphery of cutter holder comprising:
- a base;
- means for rotatably mounting an annular cutter holder on said base;
- a gauge device mounted on said base;
- said gauge device being adjustable at a plurality of positions to provide predetermined radial settings for the cutters in said cutter holders,
- wherein said gauge device comprises an eccentrically mounted disc mounted for pivotal movement so that successive positions on the edge of said disc define predetermined settings from the center of a cutter holder in which cutter blades are to be supported, and
- including measurement indicia on said base to be used for setting said eccentrically mounted disc at any one of a plurality of selectable positions for setting a cutter at a desired radial setting.
A device for setting cutter blades at predetermined positions in the periphery of cutter holder comprising:
- a base;
- means for rotatably mounting an annular cutter holder on said base;
- a gauge device mounted on said base;
- said gauge device being adjustable at a plurality of positions to provide predetermined radial settings for the cutters in said cutter holders,
- wherein said gauge device comprises an eccentrically mounted disc mounted for pivotal movement so that successive positions on the edge of said disc define predetermined settings from the center of a cutter holder in which cutter blades are to be supported and
- wherein the edge of said eccentrically mounted disc is contoured so that cutters may be set at a prescribed height as well as at a prescribed radial setting.
A device for setting blades at predetermined positions in the periphery of a cutter holder having an annular body formed with a central bore and said cutter blades extending generally radially from said cutter holder comprising, a jig having a base plate, a spindle mounted on said base plate, a rotatable set plate formed with an opening through which said spindle extends and formed with an upper flat surface normal to the axis of said spindle, said cutter holder receivable over said spindle and formed with a flat lower surface normal to the axis of said spindle for mating engagement with said upper flat surface of said rotatable set plate and said cutter holder and said set plate rotatable as a unit relative to said base plate, a micrometer mounting bracket attached to said base plate, and a micrometer mounted on said mounting bracket and having a moveable stem extending radially of said spindle and having an end which is adjustable relative to the ends of said cutter blades.
