ABSTRACT:
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.
