    • A method for completely machining at least unprocessed centric journals (10) and crankpin journals (11), and the respective flat shoulders (9, 10) thereof surrounding the journals, of flanged or cast blanks of a crankshaft first includes turning the flat shoulders (9) associated with the journals (10). Then, the centric journals (10) are roughly ground without the flat shoulders (9) thereof and the crankpin journals (11) are roughly ground together with the flat shoulders (12) thereof. After the journals (10, 11) have been roughly ground, an allowance remains that is smaller than an allowance required for common finish grinding of journals and flat shoulders. The rough grinding is followed by the finish grinding of the centric journals (10) and the crankpin journals (11) from the smaller allowance (23) remaining due to the rough grinding to the final dimension.

    • A method and a tool head are provided for the chip-removingly machining of pairwise symmetrical, optically effective surfaces, in particular of surfaces of progressive power spectacle lenses. The spectacle lenses are rotated about a first axis and are displaced along the axis. Further, a chip-removing tool is provided being positioned and being adapted to be fed-in, such that a cutting edge of the tool is guided over the surface along a spiralled path and along an elevation function given by the shape of the spectacle lens, when the latter is rotated about the first axis. For machining right side spectacle lenses and left side spectacle lenses, the right side spectacle lenses are rotated about the first axis in a first rotational direction, and the left side spectacle lenses are rotated about the first axis in a second rotational direction opposite the first rotational direction. The tool head comprises a chucking structure defining an axis of the tool head, and a tool carrier section having at least two lathing tools arranged at a periphery thereof. The one lathing tool of the pair is oriented in the one circumferential direction of the periphery, and the other lathing tool of the pair is oriented in the opposite circumferential direction of the periphery. At least one, preferably all of the lathing tools are provided with an adjustment device allowing an adjustment of a point of engagement of the lathing cutting edge.
    • 提供了一种方法和工具头,用于对成对对称的光学有效表面,特别是渐进屈光力眼镜镜片的表面的去屑加工。 眼镜镜片围绕第一轴旋转并且沿轴线移位。 此外,提供了一种定位并适于被馈入的切屑去除工具,使得工具的切割边缘沿着螺旋路径被引导在表面上并且沿着由眼镜镜片的形状给出的仰角函数 ,当后者围绕第一轴线旋转时。 为了加工右侧眼镜片和左侧眼镜镜片,右侧眼镜镜片在第一旋转方向上围绕第一轴线旋转,并且左侧眼镜镜片围绕第一轴线以与第一旋转相反的第二旋转方向旋转 方向。 工具头包括限定工具头的轴线的夹紧结构,以及具有在其周边布置的至少两个车床的工具架部分。 该对的一个车床工具在周向的一个圆周方向上定向,并且该对的另一个车床工具在周边的相反圆周方向上定向。 至少一个,优选地,所有的车床工具都设置有允许调整车床切削刃的接合点的调节装置。
