COMPOSITE CUTTING TOOL Russian patent published in 2003 - IPC

FIELD: designing of multitoothed cutting tools. SUBSTANCE: composite cutting tool has two coaxial bodies with cutting teeth installed for mutual turning relative to axis and interconnected by flexible tie to increase stability of cutting tool, accuracy and quality of machined part, flexible tie is made in form of spring installed between bodies for regulation of its force. Bodies are interconnected by means of radial thrust bearing for variation of mutual angular position. Spring may be made in form of split ring. EFFECT: higher stability of cutting tool, accuracy and quality of machined surface. 2 cl, 4 dwg
