PURPOSE: To provide a moving body feeding method in which stick slip is never caused even at ultra low speed feeding.

CONSTITUTION: A second middle table 11 is placed on the X axis direction second slide guide face 4a on a first middle table 4, which is placed on the X axis first sliding guide face 2a on the saddle 2 placed on a bed 1 and whose movement is controlled by a feed screw 6, and the movement of the second middle table 11 is controlled by a feed screw 13. When the feed speed V1 of the first middle table in the -X axis direction and the feed speed V2 of the second middle table in the +X axis direction are given, when V2>V1, the tool rest 8 of the second middle table 10 and a tool rest 8 move at a speed of the difference between V2 and V1, and can perform ultra low speed feeding without stick slip by minimizing the difference. In this case, of course, V2 and V1 are speed at which stick slip is never caused.
