Abstract
A machine tool includes a main spindle movably supported in an axial direction, and two gang tool posts disposed opposed to each other with an axis of the main spindle located therebetween. Each of the two gang tool posts is supported movably in X and Y directions that are perpendicular to the axial direction of the main spindle. Each of the two gang tool posts is provided with tools arranged parallel to each other in the Y direction. One of the two gang tool posts is movably disposed in a Z direction that is a same direction as the axial direction of the main spindle. Any one of the two gang tool posts is integrally provided with a turning tool base that turnably supports tools about a Y-axis along the Y direction.
Claims6
A machine tool comprising:
- a main spindle movably supported in an axial direction thereof,
- a second main spindle disposed opposed to the main spindle, and
- two gang tool posts disposed opposed to each other with an axis of the main spindle therebetween,
- wherein each of the two gang tool posts is supported movably in X and Y directions that are perpendicular to the axial direction of the main spindle, and each of the two gang tool posts is provided with tools that are arranged in the Y direction parallel to each other,
- wherein one of the two gang tool posts is movably disposed in a Z direction that is a same direction as the axial direction of the main spindle such that the Z direction is parallel to the axial direction,
- wherein the one of the two gang tool posts movably disposed in the Z direction is provided with an end surface tool base that moves together therewith, and
- wherein an other gang tool post of the two gang tool posts is immovable in the Z direction and integrally provided with a turning tool base that turnably supports tools about a Y-axis along the Y direction.
A machine tool comprising:
- a main spindle movably supported in an axial direction thereof,
- a second main spindle disposed opposed to the main spindle,
- a first gang tool post and a second tool post disposed opposed to each other with an axis of the main spindle therebetween, wherein the first and second gang tool posts are supported movably in X and Y directions that are perpendicular to the axial direction of the main spindle, and comprise tools that are arranged in the Y direction parallel to each other, and wherein the first gang tool post is movably disposed in a Z direction and the second gang tool post is immovable in the Z direction, the Z direction being a same direction as the axial direction of the main spindle and parallel to the axial direction of the main spindle,
- an end surface tool base disposed on the first gang tool post to move together with the first gang tool post, and
- a turning tool base integrally disposed on the second gang tool post to turnably support tools about a Y-axis along the Y direction.
