PURPOSE:To high accurately perform positioning machining, by linearly moving a shuttling slide base through rotation of a feed screw and detecting a movement amount of the slide base with a rotary position of the feed screw. CONSTITUTION:When a slide base 2 is moved, its position is detected by a resolver 6, directly connected to a feed screw 3 driving the slide base 2, and an output electric signal of the resolver is fed to an NC device 23 through contactless type rotary transformers 15a, 15b to control a driving gear 24 of the slide base 2. As a result, the driving gear of the slide base can be controlled by feeding the output signal to the NC device to perform high accurate positioning machining. |
