A long bar 20 is supplied to the automatic lathe 100 from a rear end of the first main spindle 1 by a conventionally known bar feeder or the like as a processing material. As shown in FIG. 4A, the bar 20 protrudes from the tip of the first main shaft 1 by a predetermined length and is gripped by the first main shaft 1 by the chuck 5. And the front-end | tip part which protruded from the 1st main axis | shaft 1 of the bar 20 is processed with the predetermined tool 11a with which the 1st tool post 12 was mounted | worn to the size which can be hold | gripped with the chuck | zipper 6 (step S1).

Then, as shown in FIG. 4B, the second spindle 3 is moved to the first spindle 1 side by the movement of the second spindle stock 4 in the Z2 axis direction, and the processed portion is inserted into the chuck 6. Then, the chuck 6 is closed, and the tip portion 20 a of the bar 20 is gripped by the second main shaft 3. Then, as shown in FIG. 4C, the chuck 5 of the first main shaft 1 is opened, the second main shaft 3 is retracted, and the bar 20 is pulled out from the first main shaft 1 by a predetermined length. 5 is closed, and the bar 20 is gripped by both the first main shaft 1 and the second main shaft 3 in a both-end supported state (step S2).

Then, as shown in FIG. 4D, a predetermined tool mounted on the first tool post 12 is rotated from the second main shaft 3 and is continuous with the tip portion 20a of the bar 20 while rotating both the

main shafts

1 and 3. Roughing corresponding to the shape of the product is performed as a primary processing on the part separated by a length (step S3). The processed portion 20b of the bar 20 shown in FIG. 4D is a portion subjected to roughing (hereinafter referred to as “roughened portion 20b”).

Then, as shown in FIG. 4D and FIG. 4E, the tip portion 20a is cut off by the cut-off tool 11b. And as shown to FIG. 4F, the front-end | tip part 20a is processed into the support tool 21 (step S4). At this time, center hole machining can also be performed at the tip of the rough machining portion 20b.

Then, as shown in FIG. 4G, the second main shaft 3 is moved to the first main shaft 1 side, and the tip of the support 21 is engaged with the center hole 20c formed in the roughing portion 20b, so that the roughing portion 20b The front end surface is supported (step S5). Thereby, the bar 20 is in a state where the roughing portion 20b is center-supported, and even if the length of the roughing portion 20b is relatively long, the subsequent finishing can be performed with high accuracy.

In this state, the rough machining portion 20b of the bar 20 is finished (secondary machining) with a predetermined tool mounted on the first tool post 12 while rotating both spindles 1 and 3 (step S6). .

Then, as shown in FIG. 4H, the chuck 6 of the second main shaft 3 is opened, and the support 21 held by the second main shaft 3 is discharged from the second main shaft 3 (step S7). A finished part (hereinafter referred to as “finished part”) 20d of the bar 20 held by the first spindle 1 is a part that becomes the product, and is finished into a shape corresponding to the product. Yes. In addition, when discharging | emitting the support tool 21 from the 2nd main axis | shaft 3 by step S7, as shown, for example in FIG. 4H, with the workpiece | work discharge | emission member 30 provided in the 2nd main axis | shaft 3 so that a movement was possible along the Z2 axis direction. It can discharge | emit from the front end side of the 2nd main axis | shaft 3 by extrusion.

As described above, the finishing process portion 20d, which is the first (first) product, is produced from the bar 20 by the processing steps (steps S1 to S7 (FIGS. 4A to 4H)). The finished processed portion 20d is not yet cut off from the tip of the bar 20 and is in a state of being a substantially final product. The base end side of the finished processed portion 20 d is processed to a size that can be gripped by the chuck 6.

Then, as shown in FIG. 5A, the second spindle 3 is moved to the first spindle 1 side, and the finishing portion 20d on the tip side of the bar 20 gripped by the first spindle 1 is inserted into the chuck 6. Then, the chuck 6 is closed and the finishing portion 20d is gripped on the proximal end side (step S8). Then, as shown in FIG. 5B, the chuck 5 of the first main shaft 1 is opened, the second main shaft 3 is retracted, the bar 20 is pulled out from the first main shaft 1 by a predetermined length, and the chuck 5 of the first main shaft 1 is removed. The rod 20 is closed and gripped by both the first main shaft 1 and the second main shaft 3 in a both-end supported state.

Then, as shown in FIG. 5C, while the both

spindles

1, 3 are rotated, a predetermined tool mounted on the first tool post 12 is used to pull out the bar 20 held by the both

spindles

1, 3. Roughing corresponding to the shape of the product is performed as primary processing on a portion that is continuous with the finishing portion 20d and separated from the second main shaft 3 by a predetermined length (step S9).

Then, as shown in FIG. 5C and FIG. 5D, the finishing part 20d which is the tip side of the roughing part 20b of the bar 20 is cut off with the parting tool 11b. Then, as shown in FIG. 5E, the front end side of the finishing portion 20d gripped by the second main spindle 3 is processed into the support 21 (step S10). At this time, center hole machining can also be performed at the tip of the rough machining portion 20b.

In this way, the control device 17 causes the second spindle 3 to grip the tip end side of the bar 20 whose tip portion is previously processed according to the product as the finish processing portion 20d as the support tool processing portion, and cut off the second portion. It functions as a support tool processing means that performs control so as to transfer to the main shaft 3 and process the support tool 21.

Then, as shown in FIG. 5F, the second main shaft 3 is moved to the first main shaft 1 side, and the tip of the support 21 is engaged with the center hole 20c formed in the tip portion of the roughing portion 20b. The tip side of the portion 20b is supported (step S11). As a result, the roughing portion 20b of the bar 20 is supported by the support 21 and the subsequent finishing is performed with high accuracy even when the length of the roughing portion 20b is relatively long. Can do.

In this state, the rough machining portion 20b of the bar 20 is finished (secondary machining) with a predetermined tool mounted on the first tool post 12 while rotating both spindles 1 and 3 (step S12). . A finished portion 20d ′ (see FIG. 5G) of the bar 20 held by the first spindle 1 is a portion to be the next (second) product, and is finished into a shape corresponding to the product. ing.

Then, as shown in FIG. 5G, by performing processing such as cutting with a predetermined tool on the finishing portion 20d gripped by the second main shaft 3 so as to remove the support tool 21 on the distal end side, The finished processed portion 20d held by the second spindle 3 is finally processed as the product. Then, as shown in FIG. 5H, the chuck 6 of the second main spindle 3 is opened, and the first product 22 is taken out from the second main spindle 3 and collected (step S13).

Then, after the first product 22 is collected in step S13, until the preset number of products is processed (step S14: NO), the processing steps of steps S8 to S13 (FIGS. 5A to 5H). By repeating this as one cycle, the second and subsequent products 22 from the bar 20 can be continuously processed and collected.

Thus, the control device 17 functions as a product recovery means for recovering the product 22 from the second main shaft 3 by removing the support 21 from the finished processed portion 20d.

If it is determined in step S14 that a predetermined number of products have been processed (step S14: YES), the above-described series of processing operations are terminated. In addition, when the first product is processed, the support 21 is discharged and the product 22 that has been processed is collected in a discharge device (not shown) provided on the second spindle 3 side or in the second spindle 3. A workpiece discharge member 30 as a moving body is provided so as to be movable along the Z2 axis direction, and the workpiece discharge member 30 is pushed toward the tip end of the second main shaft 3 and further pushed out toward the tip end side of the second main shaft 3. It can be performed by a conventionally known means such as extrusion from the base end side of the second main shaft 3 by the material 20 held by the first main shaft 1.

In this way, when the first product is processed, the tip 20a of the bar 20 is processed into the support 21 as a support tool processing part, and the bar 20 is supported by the support 21 held by the second spindle 3. When the second and subsequent products are processed after supporting the tip of the rough processed portion 20b, the finished processed portion 20d gripped by the second spindle 3 is processed into the support tool 21 as a support tool processing section. By supporting and processing the tip of the bar 20, the processing can be stably performed, and the product can be processed with high accuracy.

Further, when the finishing part 20d to be the first product is processed, after the support 21 to be a non-product is discharged, the finishing part 20d to be the second and subsequent products is to be processed second. A support 21 is integrally formed at the end of the finishing portion 20d that is in a state of being held by the main shaft 3, and after completion of the finishing of the bar 20 held by the first main shaft 1, its tip Only the part can be discharged as a non-product. Therefore, the ratio of the support tool discharged from the bar 20 as a non-processed product can be reduced, and the use efficiency of the material when processing a product having a predetermined shape from the bar 20 can be improved.

The automatic lathe 100 of the present embodiment shown in FIG. 1 is a so-called main shaft moving type in which the first main shaft 1 is movable in the Z1 axis direction, but as shown in FIGS. 4A to 4H and FIGS. 5A to 5H. When the first spindle 1 is not moved in the Z1 axis direction, the automatic lathe 100 is fixed in a state in which the first spindle 1 is not movable in the Z1 axis direction, and the first tool post 12 is movable in the Z1 axis direction. It is also possible to use a so-called main shaft fixed type provided in the main body. On the other hand, as shown in FIG. 1, when a so-called spindle moving type automatic lathe is used, the machining operations shown in FIGS. 4A to 4H and FIGS. 5A to 5H are performed so that the first spindle 1 moves in the Z1 axis direction. It can also be configured.

When an unexpected power failure or erroneous operation occurs during the machining operations shown in FIGS. 4A to 4H and 5A to 5H of the above-described embodiment, the closed state of the

chucks

5 and 6 is released, and the

chucks

5 and 6 are released. May be open.

For example, in the machining operation states shown in FIG. 4H, FIG. 5G, and FIG. Even when the bar 20 is gripped by 5, the bar 20 held by the chuck 5 on the first main spindle 1 side may be misaligned.

For this reason, when the chuck 5 is closed with respect to the storage means such as the memory on the control means 17 side corresponding to each machining operation (machining process) shown in FIGS. 4A to 4H and 5A to 5H. Can be set so that once the chuck 5 is opened, the flag is lowered. For example, in FIGS. 4C and 5B, after a command from the control device 17 side that closes the chuck 5 of the first spindle 1, a flag (“1”) is set for the storage means, and the chuck 5 is once closed. When the detection signal is interrupted, the set flag can be reset. The flag can be automatically set in accordance with the chuck 5 closing command, or can be instructed to set the flag after the chuck 5 closing command.

As described above, the control unit 17 is configured as a detection unit that detects the switching from the state in which the bar 20 is gripped by the first spindle 1 to the non-grip state by setting and resetting the flag for the storage unit. To function. Accordingly, when the chuck 5 is opened during the machining operations (each machining step) shown in FIGS. 4C to 4H and 5B to 5H, the flag is reset, and the control device 17 once closes the chuck 5 to make the product It can be determined that an unexpected opening operation of the chuck 5 has occurred during the machining of the chuck 22.

For example, when the chuck 5 is configured to open and close the chuck 5 by an extension operation or contraction operation of the cylinder, the flag is automatically reset by detecting the release of the extension or contraction state of the cylinder. Can do.

In this case, the control device 17 functions as reworking means, interrupts and stops the subsequent normal machining operation (machining process), and cuts off the processed portion of the bar 20 gripped again by the chuck 5 with a parting tool. Returning to the first machining operation (machining process) shown in FIG. 4A, the machining is started from FIG. 4A. Thereby, it is possible to prevent a defective product from being produced.

When the work discharge member 30 as a moving body is provided in the second main shaft 3 so as to be movable along the Z2 axis direction, as shown in FIG. The tip part 30a to be provided can be provided as a support.

For example, during the machining operation shown in FIG. 5F described above, as shown in FIG. 7, the workpiece discharge member 30 is gripped by the chuck 6 and fixed to the second main spindle 3 side, and the tip portion 30a is fixed to the first end 30a. The front end side of the roughing portion 20b can be supported by engaging the front end surface (center hole) of the roughing portion 20b of the bar 20 gripped by the chuck 5 on the one main spindle 1 side.

In this way, the roughing portion 20b on the first spindle 1 side is used as the tip surface (center) by using the workpiece discharge member 30 provided in the second spindle 3 as a support without processing and gripping the support on the chuck 6. It can be easily supported on the hole) side, the use of unnecessary materials can be suppressed, the use efficiency of the materials can be improved, and even if the length of the roughing portion 20b is relatively long Subsequent finishing can be performed with high accuracy.

The tip portion 30 a is prepared by previously forming the tip of the workpiece discharge member 30 into a protrusion shape, and is prepared separately from the workpiece discharge member 30 so that the tip portion 30 a can be attached to and detached from the tip of the workpiece discharge member 30. It can be installed.

It is also conceivable that the roughing portion 20b is supported by the tip portion 30a without gripping the workpiece discharge member 30 by the chuck 6. Incidentally, since the work discharge member 30 is provided in the second main shaft 3, the product 22 is collected by moving the work discharge member 30 toward the front end of the second main shaft 3 as shown in FIG. This can be done easily by extruding the product 22 to the distal end side of the second spindle 3 through the portion 30a.

In addition, by accommodating the workpiece discharging member 30 in the second main shaft 3, the bar 20 that has been subjected to the roughing process is cut through and transferred from the first main shaft 1 to the second main shaft 3 to perform the secondary processing. After completion, the product 22 can be recovered by being pushed out of the second main spindle 3 by the work discharge member 30.
