    • The present invention relates to a machine tool for machining of workpieces, having a workpiece support for mounting the workpiece, a tool holder, which can be moved at least along one axis, for holding a tool for machining the workpiece, and workpiece holding units for fixing the workpiece during the machining, the workpiece holding units being arranged outside the workpiece support surface of the workpiece support, which is covered by the workpiece in the mounted state, and each having a holding element for fixing the workpiece. In order that also workpieces of greater diameter can be machined, the machine tool otherwise being of the same dimensions, it is provided according to the invention that the holding elements can each be moved, substantially parallel to the workpiece support surface, in the direction of the workpiece, in particular in the direction of a central workpiece axis, which runs perpendicular to the workpiece support surface, for the purpose of centering and fixing the workpiece. The holding elements comprise a clamping surface that is arranged obliquely in relation to the workpiece support surface and that is, in the mounted state, pressed against the workpiece for fixing and centering the workpiece to be machined, thereby exerting a pressure both in the direction of the workpiece support surface and in the direction of the central workpiece axis.
    • 本发明涉及一种用于加工工件的机床,具有用于安装工件的工件支撑件,可至少沿着一个轴线移动的工具架,用于保持用于加工工件的工具,以及用于 在加工期间固定工件,工件保持单元布置在工件支撑件的工件支撑表面的外侧,工件支撑表面在安装状态下被工件覆盖,并且每个具有用于固定工件的保持元件。 为了也可以加工更大直径的工件,机床具有相同的尺寸,根据本发明,提供了保持元件可以基本上平行于工件支撑表面沿着 工件,特别是在垂直于工件支撑表面延伸的中心工件轴线的方向上,用于定心和固定工件。 保持元件包括相对于工件支撑表面倾斜地布置的夹紧表面,即处于安装状态的夹紧表面被压靠在工件上,用于固定和对准待加工的工件,从而在 工件支撑表面和中心工件轴线的方向。

    • A machine tool has a work space (17) in which a device (15) for accommodating workpieces (16) to be machined is arranged. The machine tool further has a work spindle (18) for machining the workpieces (16) and a slide (34) which carries the work spindle (18) and is traversable in a longitudinal direction relative to the device (15), a respective cover (25), variable in length in the longitudinal direction (x), for the work space (17) being provided on the slide (34) on each of its sides, said cover (25) being connected with its respective first end to the slide (34) and with its respective second end to a side wall (21, 22; 51) of the work space (17). Each cover (25) variable in length has a respective rear wall (26) and a respective top (27), whereby the top (27) is connected to the rear wall (26) in a detachable, push-in, manner. A further flexible cover (31) is arranged in front of the slide (34) to protect the work space (17) at the bottom. The flexible cover (31) is variable in a direction (y) orthogonal to the longitudinal direction (x) and is partly designed as a link apron (54).
    • 一种机床具有工作空间(17),其中布置有用于容纳待加工的工件(16)的装置(15)。 机床还具有用于加工工件(16)的工作轴(18)和承载工作主轴(18)的滑动件(34),并且可相对于装置(15)在纵向方向上移动;相应的盖 (25),其长度方向(x)的长度可变,对于工作空间(17),每个侧面上设置在滑动件(34)上,所述盖(25)与其相应的第一端连接到 滑动件(34)并且其相应的第二端连接到工作空间(17)的侧壁(21,22; 51)。 长度可变的每个盖(25)具有相应的后壁(26)和相应的顶部(27),由此顶部(27)以可拆卸的推入方式连接到后壁(26)。 另一个柔性盖(31)布置在滑动件(34)的前面,以保护底部的工作空间(17)。 柔性盖(31)在与纵向方向(x)正交的方向(y)上是可变的,并且部分地设计为连接围裙(54)。
