色々と苦労があつた。Conventional technology The tool rest of a normal NC lathe often has a separate turret tool rest for turning tools and a turret tool rest for rotary tools, and the turret rests are placed in a standby position to avoid interference with the chuck, tailstock, or each tool rest. are doing. For this reason, when a command for outer diameter, inner diameter or hole drilling is issued, the stroke for selecting a tool and positioning the tool in the processing device becomes long, resulting in an unexpectedly large amount of idle time. Furthermore, when a large number of tools are mounted on one tool post, the chuck, tailstock, and tool post tend to interfere with each other, making it difficult to arrange and control the tools to avoid this.

面９ｃには工具取付部は必ずしも設けない。Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. In a known multi-tasking lathe, a main spindle 2 is rotatably and indexably supported on a headstock 1 on a bed (not shown), and a workpiece W is gripped by a chuck 3 fitted on the end of the main spindle. There is also a headstock 1 on the bed.
A tailstock 6 having a tailstock shaft 5 on which a center 4 is fitted is placed opposite to the tailstock 6 . Furthermore, the carriage 7 placed on the Z-axis direction guide surface on the bed is not shown.
Positioning is controlled by a feed screw from an NC-controlled servo motor. A transverse feed table 8 is mounted on the reciprocating table 7 so as to be slidable in the X-axis direction, and its position is controlled by a feed screw from an NC-controlled servo motor (not shown). A square tool rest 9 that can be rotated and indexed is provided on the cross feed table 8, and a rotating shaft 10 having axes perpendicular to each of the X and Z axes is provided.
The four corner sides 9a, 9b, 9c, 9d
is indexed parallel to the Z axis. The side surface 9a of this square indexing tool rest 9 is provided with rotary tool mounting portions A and B with tapered shank whose axes are perpendicular to the rotation axis and parallel to each other at two positions symmetrical with respect to the rotation axis 10. The tool is conveyed from the magazine to the receiving hole of the taper shank by an exchange arm (not shown). Rotation is transmitted to the rotary tool mounting portions A and B from a separate motor (or on the tool rest) via gears (not shown) built into the tool rest 9, respectively. Normally, the rotary tool attachment part A is equipped with a tool T1 for machining the outer periphery of the workpiece, such as an end mill, and the rotary tool attachment part B is equipped with a tool T2 for machining the end surface of the workpiece, such as a drill. Also, the left side (first side) adjacent to side 9a
Figure) On the right side 9b and 9c, a turning tool with a taper shank with an axis perpendicular to the rotation axis and on the same axis or parallel to the rotation axis is mounted on the opposite side of the rotary tool attachment parts A and B with respect to the rotation axis. Sections C and D are provided,
Each has a tapered shank receiving hole. Normally, the outer diameter turning tool T3 is attached to the attachment portion C, and the inner diameter cutting tool T4 is attached to the attachment portion D, respectively. Note that a tool attachment portion is not necessarily provided on the side surface 9c.

Mounting part D has a boring or internal cutting tool T4
is installed and controlled by NC. In the machining sequence, for example, as shown in FIG. 2, the side surface 9b of the tool post 9 is indexed in the Z-axis direction, and the outer periphery of the workpiece W is cut with the tool T3. Also, cutting of the end face is performed. Next, as shown in FIG. 3, the side surface 9a of the tool rest 9 is indexed parallel to the Z-axis, the main shaft is indexed to the C-axis, and a flat portion or key groove is cut on the outer periphery using the tool T1. Next, as shown in FIG. 4, the side surface 9a of the tool rest 9 is indexed parallel to the X-axis, and a hole is drilled in the end surface of the workpiece W using the tool T2. Next, as shown in FIG. 5, the side surface 9d of the tool rest 9 is indexed parallel to the X axis, and the inner diameter of the workpiece W is cut and bored using the tool T4. The processing order is not limited to this.

ログラムが容易となる特徴を有する。Effects As detailed above, the present invention has a four-cornered indexing tool rest with one outside diameter tool and one inside diameter tool on both sides with respect to the center of rotation, and a rotary tool on the other side of the tool rest. Since it is installed in two positions symmetrical to a line that passes through the center of the rotation axis and is parallel to the side surfaces 9c and 9d, the tool rest can be rotated even when changing the cutting area or cutting content, resulting in slight X and Z changes. By simply moving the axis, the tool can be positioned at the machining position in an extremely short time, reducing idle time and enabling efficient machining. In addition, since the tools are arranged on one turret with consideration to the machining direction, there is less interference with the chuck, tailstock, lower turret, etc., making operations and programming easier.
