Abstract

835,995. Cutting-tools for lathes, milling- machines &c. BOOTH, C. H. July 6, 1956 [June 29, 1955; July 14, 1955], Nos. 18867/55 and 20362/55. Class 83 (3). [Also in Group XXIII] A cutting-tool for lathes, milling-machines, &c., comprising a main body and an insert of hard cutting material, of generally geometric shape and whose length is preferably greater than the width or diameter, has the insert arranged so that the direction of length of the insert extends along the mean path of recession of the cutting-edge at successive sharpenings. In a turning-tool 1, Figs. 1 and 3, having an insert 8 cutting a workpiece 2, the top face 4 and the side face 6 wear away and require a first resharpening by the amounts c and a respec. tively. So long as the rate of tool-wear remains constant, the cutting-edge e will move, due to successive sharpenings, along a path represented by the line x-x. The insert, in this example rectangular, is mounted in the body so that its longitudinal axis lies in the direction x-x. Inserts of circular section, some with coolant passages, are described. Milling cutters.-A carrier hub or disc 20, Figs. 10-12, of medium carbon steel or other relatively cheap material, has toothed segments 21 secured thereto by tongues 22 fitted into a circumferential groove 23 in the hub, and is secured by rivets 24. The hard-metal cutting- inserts 88, 89 are of I-section, slotted into the segments and secured by welding or brazing. These inserts are alternately high-and-narrow and broad-and-low, to facilitate chip-clearance, and are arranged at an angle of up to about 50 degrees with the radius so that the axis of the insert lies along the path of recession of the cutting-edge e for successive sharpenings. The broad inserts may be in two pieces welded to the segment faces, while the narrow inserts may be held in box-like recesses formed by making the segments of double thickness. A solid construction may be used in place of the segmentalarrangement shown. The constructions are applicable to circular and straight-cut saws (Group XXIII).
