Abstract
683,355. File-cutting machines. MUNDORF, H. Jan. 23, 1951 [Feb. 21, 1949], No. 1759/51. Class 83 (iv). In a file-cutting machine of the type where there is relative longitudinal movement between the cutting tools and file blanks 5, 6, and oppositely - acting cutting - tools 8, 9 act simultaneously on opposite file surfaces, the cutting- tools are moved along the surfaces of the file blanks which are clamped in a fixed position. Two blanks are clamped on a fixed saddle and a movable table 7 carries oppositely acting first cut and second cut tools 9, 8, respectively, smoothing files 12, 13, for trimming the first cut teeth, and edgecutting tools 17, 18. Guide surfaces 19, 20 conform to the profile of the blanks and ensure a uniform depth of cut. The tools are automatically brought into operation and disconnected successively by couplings 14, 15, which connect the tools 9, 8, respectively, to driving shafts a, b, and by a coupling connecting tools 17, 18 to driving-shaft 16, the couplings being controlled by rods 21 &c. coacting with stops on the table 7.
