Inner diameter machining tool and an inner diameter processing method

摘要

PROBLEM TO BE SOLVED: To improve a cooling effect and a lubrication effect by surely spreading a sufficient amount of a coolant to a cutting part without degrading insert seating stability even in an insert attaching/detaching type tool.;SOLUTION: In a tool for machining an inner diameter used by being inserted in a machining hole H formed on a cutting object material W to be rotated around a rotating axis L for machining an inner peripheral surface of the machining hole H, a cutting edge 40 protruding to an outer periphery side in the radial direction for the central axis O of a tool body 1 extending axially is arranged at a tip of the tool body 1, and a coolant hole 17A for jetting coolant C to an axially orthogonal plane P orthogonal to the central axis O and extending along the direction of protrusion in which the cutting edge 40 protrudes is opened at a position apart from a position where the cutting edge 40 protrudes in the circumferential direction of the tool body 1 by facing a direction different from the direction of protrusion of the cutting edge 40 in the radial direction for the central axis O.;COPYRIGHT: (C)2014,JPO&INPIT
