MILLING TOOL

摘要

The purpose of the present invention is to enable high-efficiency cutting in the rough working of a super heat-resistant alloy or other difficult-to-machine material, and to suppress abnormal wear of the side surface of a blade edge and enable long-lasting cutting work even when a standing wall surface is being formed. A milling tool having a plurality of cylindrical button tips arranged at equal intervals in a circumferential direction, wherein the button tips are divided into groups of button tips arranged at angles around the same circle centered around the rotational axis of the milling tool. At least one of these groups is divided into a group of button tips for cutting the floor surface of a material to be cut and a group of button tips for cutting the standing surface of a material to be cut, by displacing the tip-mounting angles, the distance from the center of the tool rotational axis in the radial direction of the tool, and the distance in the tool rotational axis direction, relative to the other groups.
