Abstract
303,496. O. K. Tool Co., Inc., (Assignees of Weddell, R. R. Jan. 6, 1928. [Convention date]. Milling-cutters; tools and tool-holders.-In an inserted blade cutting tool for metal-cutting or other machine-tools, which may be either rotary or non-rotary, the body or holder is provided with one or more recesses which taper in two perpendicular directions and the blades are similarly shaped to be secured therein by wedging action. Serrations are provided on one side of each blade to coact with serrations on a side of the recesses. As applied to a face milling-cutter the blades 12 are secured in recesses 11 in the body 10, the blades being inclined slightly to the axis of the cutter and also to radii in order to provide cutting rake. The blades and recesses are tapered in each direction, as shown in Figs. 2 and 5 and the blades have two cutting edges 12<a>, 12<b>. In order to adjust the blades, after re-grinding or otherwise, the serrations on the blades are made to engage with different serrations in the recesses thus causing each of the cutting edges to be displaced. The relative amounts of such displacement are determined by the relative amounts of the taper in the two directions, As applied to a side milling-cutter, the blades 19, Fig. 7, are inclined to the axis of the cutter alternately in opposite directions and are tapered alternately as shown and also converge towards the axis. The serrations in the recesses may be displaced progressively round the body so that moving a blade from one recess to the next will adjust the blade by an amount less than the pitch of the serrations, and in the case of the side cutter the progressive arrangement affects alternate recesses in opposite directions.
