    摘要： Two separate drive systems for driving a rotary table about an axis of rotation relative to a support member within a predeterminable angular segment. The first drive system can move the rotary table into a starting position and the second drive system is a linear one and has a play-free pre-loaded ball-and-screw spindle drive by means of which the movement of the rotary table is performed within the predeterminable angular segment. The linear drive system can be coupled and uncoupled free from play to and from the rotary table by means of a clamping system, with the linear drive system being connected to the support member and to the clamping system with two play-free joints. A rotary measuring system is mounted at the axis of table rotation to ascertain the table's current angle of rotation. Once the rotary table has been moved to the starting position, the first drive system is switched off and the second drive system is rigidly connected to the rotary table by the clamping system, and thereafter the table is moved free from play by the spindle drive powered by a servomotor under CNC control.

    摘要： A CNC machine for producing spiral-toothed bevel gears is described, which has a first carriage supporting a tool spindle and is displaceable in height, and whose guide is disposed on a lateral surface of a machine housing, which is horizontally guided in a straight coordinate axis on a machine base. The tool spindle axis is parallel with the lateral surface and with the coordinate axis. Furthermore, the machine has a workpiece spindle support having a second carriage and a pivoting device with a vertical axis and is also horizontally guided on the machine base. The parallel arrangement of the tool spindle axis results in a new machine concept with a compact structure and optimal chip flow. Therefore the machine is particularly suited for heavy-duty dry milling. Since the tool spindle is not located above the area of the machine having a horizontal guide, it is possible to arrange a chip collector underneath the tool spindle, which can be reached by the chips essentially under the force of gravity.

    摘要翻译： 描述了一种用于生产螺旋齿锥齿轮的数控机床，其具有支撑工具主轴并且可高度移动的第一滑架，并且其引导件设置在机器壳体的侧表面上，其以直线坐标水平引导 轴在机器基座上。 刀具主轴与侧面和坐标轴平行。 此外，机器具有工件主轴支撑件，其具有第二托架和具有垂直轴线的枢转装置，并且还在机器基座上水平引导。 刀具主轴轴的平行布置使得新的机器概念具有紧凑的结构和最佳的切屑流。 因此该机特别适用于重型干磨。 由于工具主轴不位于具有水平导轨的机器的区域之上，所以可以在工具主轴的下方布置芯片集合体，该芯片可以在重力作用下由芯片实现。
