Abstract:
A tool for chip removing machining comprising a rotary head defining a longitudinal axis of rotation, the head including:an envelope surface arranged generally symmetrically relative to the axis; a forwardly facing front end surface extending transversely relative to the axis; a plurality of chip spaces formed in a transition region between the envelope surface and the end surface; a plurality of circumferentially spaced insert seats configured for receiving respective cutting inserts, each insert seat disposed in a respective chip space; a duct extending generally longitudinally within the head for conducting fluid forwardly to the front end surface; and a plurality of grooves formed directly in the front end surface and each groove extending along the front end surface transversely of the axis from an inlet end of the groove to an outlet end of the groove, the outlet ends of the grooves communicating with respective chip spaces, and the inlet ends of the grooves communicating with fluid from the duct, wherein the grooves conduct fluid from the duct all the way to respective chip spaces in response to rotation of the head.
