Abstract

1347237 Boring bar BROOKE TOOL MFG CO Ltd 3 May 1971 [4 Feb 1970] 5328/70 Heading B3C A boring bar comprises a cutter 2 having helical teeth 18 which co-operate with the screw threads of an adjusting screw member 8, the latter being rotatable, lens fixed against axial movement. The radial position of the cutter is adjusted by rotating the screw, the adjusted position being indicated on a scale 11, and the cutter is then secured by set screws 20, 21. Backlash is taken up by a spring washer 19. In a modification, the cutter is located at an angle so as to cut forwardly of the boring bar, Fig. 4 (not shown). Screw member 8 may be retained by a screw 17, a grub screw (33), Fig. 4 (not shown), a locknut (34), Fig. 5 (not shown), or by a collar and split dowel (38), Fig. 6 (not shown).
