ABSTRACT:
An improved cutter head in a machine tool includes a cutter head main body, a cutter spindle that is rotatably supported by the cutter head main body and adapted to be rotatably driven, a cutter support carried by the cutter head main body so as to be rotatable and movable along the axial direction of the cutter spindle, and a support shaft that is rotatably supported by the cutter support so as to be coaxial with the cutter spindle. At the tip end of the support shaft is formed a collet section having an expansible and contractible diameter so that the tip end of the cutter spindle can be fitted in the inner circumference of the collet section, resulting in expansion of the diameter of the collet section, and a cutter can be fitted around the outer circumference of the collet section. The improved cutter head further includes a clamp device for clamping the cutter fitted around the outer circumference of the collet section by bringing the cutter spindle and the support shaft close to each other under the state where the tip end of the cutter spindle is fitted in the collet section of the support shaft.
