Patent attributes
A cutting tool includes a tubular body made of a composite material, such as carbon reinforced fiber polymer (CFRP). A front support structure comprising a central hub and a plurality of spokes extending radially outward from the central hub is attached proximate the front end of the tubular body. A rear support structure comprising a central hub and a plurality of spokes extending radially outward from the central hub is attached proximate the rear end of the tubular body. Cartridge supports are attached directly to one of the front and rear support structures. A rear machine connection member is attached to the rear support structure for providing coolant to the front and rear support structures. The CFRP tubular body increases the stiffness to weight ratio of the cutting tool.
