<p>A numerical controller which controls multiple spindles through a plurality of channels (10, 20, 30). When the machining program of the first channel (10) is stopped in response to a single block signal (6), the machining programs of other channels (20, 30) are placed under the feed-holding condition. This makes it possible to maintain synchronism in executing the whole machining program and to prevent the machining from losing balance and from interfering.</p> |
