Abstract
A tool for chip removing machining includes a holder and a tool head removably attached to the holder by screws. The head, which carries at least one cutting insert, has a serrated surface mated with a serrated surface of the holder. Those serrated surfaces define an interface between the holder and the head which is oriented at a 45 degree angle with respect to a basal plane extending through the holder and containing a longitudinal axis thereof.
Claims9
A tool for chip removing machining, comprising a holder and a tool head connected therewith, the holder defining a central longitudinal axis, the tool head including an insert-receiving seating surface on which a cutting insert is to be seated, the holder and the tool head including mutually facing connecting surfaces engaging one another to define a dividing plane therebetween, connecting members provided for rigidly connecting the tool head with the holder, the dividing plane extending in a direction generally perpendicular to a plane of the seating surface and forming a substantially 45° angle with a basal plane of the holder that extends in a direction generally perpendicular to the plane of the seating surface and that contains the longitudinal axis of the holder and intersects the connecting surface of the holder at an intermediate location substantially midway between axially foremost and rearmost ends of such connecting surface as seen when viewing the tool head in a direction perpendicular to a plane of the seating surface, wherein the basal plane forms an angle of substantially 45° with the dividing plane.
A holder defining a longitudinal axis and comprising a coupling part at a first longitudinal end of the holder and a connecting part disposed at a second longitudinal end thereof, the connecting part including a connecting surface facing away from the first longitudinal end and forming a substantially 45° angle relative to a basal plane that contains the longitudinal axis of the holder and intersects the connecting surface of the holder at an intermediate location substantially midway between axially foremost and rearmost ends of the connecting surface, the basal plane forming with the connecting surface an angle of substantially 45 degrees, wherein the connecting surface includes parallel serrations formed therein, each serration having opposing ends extending to an outer periphery of the connecting surface, one of the ends of each serration disposed axially forwardly with respect to the other end, wherein the basal plane passes substantially midway between the opposite ends of each such serration.
