ABSTRACT:
In a tool-indexing apparatus, the apparatus comprises a member being moved in a linear direction, one set of ball screws which connects between the member and a tool-post, a stopper which restricts the linear movement of the tool-post, and two coil springs which resist against the linear movement of the tool-post and the member. During the operation of the apparatus, first, the member together with the tool-post are lifted, and after the tool-post has become abutted against the stopper via one of the two coil springs, the tool-post is revolved by means of one set of ball screws and by the other one of the coil springs for establishing the tool-indexing operation of the apparatus.
