Abstract
There is disclosed a feed system for a rotating cutting tool which is driven by a spindle and is adjustable in the feeding direction via an adjusting means. The adjusting means is driven by an operating shaft which can be driven synchronously with the spindle or at a predetermined difference in speed with respect to the spindle by a separate feed motor. In the case of a synchronous drive of the operating shaft and the spindle no feed is effected, whereas the cutting tool is adjusted, when a speed difference is adjusted by the adjusting means. After adjusting the desired position of the cutting tool, the operating shaft and the spindle are again driven at the same speed.
