Abstract
1290221 Boring bars MUREX Ltd 19 April 1971 [25 Feb 1970] 9185/70 Heading B3C A cartridge for use in a boring bar comprises a tapered member 2 adapted to be fixed to the boring bar by screws 8, a second tapered member 4 releasably secured to member 2 by a bolt 36, and adapted to be adjusted relative to member 2 by an eccentric 16 actuated by a key 50, and a cutter 32 mounted on member 4. Movement of member 4 along with cutter 32, along member 2, varies the cutting diameter of the boring bar, the degree of adjustment being indicated by calibrations 60, 62.
