Japanese Patent JP6538062
Kind Code:
B2
Abstract:
A rotating cutting tool that iscylindlly cooled by cryogenic coolant, the rotating cutting tool has a cylindrical body including: a central bore that extends along a longitudinal axis of the cylindrical body; a plurality of cold flow delivery paths formed from radial bores that fluidly communicate with and extend radially-outwardly from the central bore; longitudinal grooves that are formed along an outer surface of the cylindrical body extending along the longitudinal axis and fluidly communicating with the radial bores; a bushing having an inner diameter closely conforming to the outer surface of the cylindrical body allowing the bushing to concentrically fit over the cylindrical body and the longitudinal grooves to form longitudinal passageways extending from the radial bores to one or more exhaust ports formed in the bushing proximate a rear face of the cylindrical body; and a plurality of cylinder for cutting a workpiece each having a cutting edge formed from the bushing.
