Abstract
A machine tool includes a bed including a bottom surface and legs arranged at three positions of the bottom surface. The bed includes two oblique sides arranged such that the bottom surface has a triangular shape. The machine tool also includes a first support surface arranged on the bed and extending along a substantially horizontal first axis, a work table supported by the first support surface so as to move along the first axis, a second support surface arranged on the bed and extending along a substantially horizontal second axis, which is perpendicular to the first axis, and a machining unit supported by the second support surface so as to move along the second axis. The second support surface is located higher than the first support surface.
Claims19
A machine tool comprising:
- a bed, the bed including:
- a bottom surface having a triangular shape, the bottom surface extending in a horizontal plane;
- two oblique plates, each having a respective major plane extending obliquely with respect to a vertical plane and the horizontal plane;
- and
- two side plates, a first of the two side plates being disposed above a first of the two oblique plates, and a second of the two side plates being disposed above a second of the two oblique plates;
- legs arranged at three positions of the bottom surface, wherein
- the first of the two oblique plates meets the bottom surface at the horizontal plane so as to form a first outer edge of the triangular shape, and the second of the two oblique plates meets the bottom surface at the horizontal plane so as to form a second outer edge of the triangular shape,
- the first of the two oblique plates extends from the first outer edge to the first of the two side plates and forms a respective oblique edge therewith, the respective oblique edge being oblique with respect to the vertical and horizontal planes,
- the second of the two oblique plates extends from the second outer edge to the second of the two side plates and forms a respective oblique edge therewith, the respective oblique edge being oblique with respect to the vertical and horizontal planes.
A machine tool, comprising:
- a bed;
- first guide rails arranged on the bed, the first guide rails extending along a substantially horizontal first axis;
- a work table supported by the first guide rails such that the work table moves back and forth along the first axis;
- second guide rails arranged on the bed, the second guide rails extending along a substantially horizontal second axis, which is perpendicular to the first axis;
- a machining unit supported by the second guide rails such that the machining unit moves back and forth along the second axis;
- third guide rails arranged at the machining unit, the third guide rails extending along a substantially vertical third axis;
- wherein
- the machining unit includes a machining shaft unit which is supported by the third guide rails such that the machining shaft unit moves in a vertical direction along the third axis, the machining shaft unit including a tool for machining a workpiece on the work table, wherein
- the second guide rails are located at a position higher than the first guide rails,
- a center of gravity of the machine tool is located at a position lower than a center of gravity of the machining unit thereof, and
- the center of gravity of the machining unit is located at a position lower than the second guide rails.
