<p>The present invention relates to a milling cutter comprising: a rotation unit which is installed in a machine tool and is rotated by the machine tool; a body unit which is installed along an outer circumferential face of the rotation unit and in which a plurality of installation grooves for installing a plurality of blades, respectively, are formed along the outer circumferential face, and one face for forming the installation grooves is provided as an inclination face to prevent the blades from being separated from the installation grooves when the rotation unit rotates; and a support unit which is installed in the body unit and supports the blades such that the blades come in close contact with one face of the body unit forming the installation grooves and the other face of the body unit facing one face of the body unit. Accordingly, it is possible to effectively prevent the blades from being separated from the installation grooves. Therefore, a workpiece is prevented from being broken and safety of a worker is effectively secured. In addition, a structure of installing the blades on the body unit is simplified, and a large number of blades can be installed on the body unit.</p> |
