MILLING TOOL

摘要

A rotatable milling tool includes a body, and at least one set of circumferentially spaced cutting members that are intersected by a common plane oriented perpendicularly to a longitudinal center axis of the body. The set of cutting members includes at least three cutting members mounted in an envelope surface of the body. Each cutting member includes a flank surface and a cutting edge disposed adjacent to the flank surface. Each cutting edge has axially spaced apart ends. The flanked surface of each cutting member forms a clearance angle with a tangent extending through the respective cutting edge. The flank surface of the insert has a larger clearance angle than the flank surfaces of at least two other inserts in the same set. During a milling operation, the cutting members with smaller clearance angles tend to produce stability and vibration-free rotation, while the cutting member having the larger clearance angle ensures a high precision (smooth) machining.
