INTERNAL DISC-TYPE MILLING CUTTER

摘要

An internal disk milling cutter for the milling of workpieces includes a one-piece annular base body. Insertable tool bit holders are arranged around a circumferentially internal surface of the annular base. Most of the holders are in the shape of circular segments and have frontal surfaces engaging the frontal surfaces of the adjacent holders. One holder has frontal surfaces which are non-diverging in the radially outward direction. An adjacent holder has a frontal surface of the one holder. A clamp wedge is disposed in either of such opposing frontal surfaces to clamp all of the holders circumferentially together. The holders bear radially outwardly against the base at circumferentially spaced locations which are in the vicinity of the frontal surfaces.
