With the above structure, as shown in Fig. 2, the movement of the saddle 1 causes the support stand 4, and therefore the turret tool rest 5, to move in the X-axis direction, and the movement of the cross slide 2 also moves the support stand 4 in the X-axis direction. Moving is similar to a normal machine tool. Furthermore, by rotating the support base 4 by 90 degrees around the vertical indexing shaft 3 provided on the cross slide 2, the horizontal indexing shaft 6 of the Klett tool rest 5 is moved in the direction of the axis of the head stock (
2 axes) or perpendicular to these (X-axis).

In the device of the present invention, the horizontal indexing shaft 6 is set as the NC axis, so that the turret tool rest 5 can be indexed at any angle, so that it functions as a Y-axis indexer. I can do that. That is, when positioning the rotary tool 8 at point A in the figure as shown in Fig. 4, if the rotary tool is at position 21, the height a of point A in the Y-axis direction is a = R sin Rotate the turret tool rest 5 by an angle α to move the rotary tool to point B so that the radius from the center of rotation of the table to the center of the rotary tool becomes If the saddle 1 or cross slide 2 is moved by -Rcos α=R (1-cos α), the rotary tool will be positioned at point A. Therefore, in order to move the entire conventional turret tool rest device in the vertical direction The Y-axis sliding mechanism can be omitted.

As explained above, in the numerically controlled machine tool of the present invention, the indexing of the tool post is performed using the NG axis, so the positioning of the rotary tool is achieved by rotating the tool post by the required angle, adjusting the saddle, and adjusting the position of the rotary tool.
This can now be done in combination with the movement of the cross slide, making it possible to omit the conventional Y-axis sliding mechanism and sliding surface, making this machine that much more compact, and making it easier to index the turret tool rest. The previously used indexing drive motor is no longer required, and by providing the fixed origin (dog and switch) of the turret tool post on the disc brake and support base, the turret position confirmation switch that was previously used is no longer necessary. The practical effects are remarkable.
