しかし前記工作機械の場合、材料の加工前に予め支持具を準備する必要があるという欠点があった。また対向軸として第２主軸を使用するため、製品の加工工程の中に製品の背面側加工がある場合、製品の加工上の制約が発生したり、多品種少量の複数の製品を順次加工する加工工程で、前記第２主軸を使用する加工工程等の場合、支持具を保持する支持具専用の支持台等の特殊で高価な設備を必要とする等の欠点もあった。   However, the machine tool has a drawback that it is necessary to prepare a support in advance before processing the material. In addition, because the second spindle is used as the opposing shaft, if there is backside processing of the product in the product processing process, there will be restrictions on the processing of the product, or multiple products of a small variety of products will be processed sequentially. In the case of a machining process using the second main shaft in the machining process, there is a disadvantage that special and expensive equipment such as a support stand dedicated to the support holding the support is required.

上記課題を解決するための本発明の工作機械は、加工用の材料を把持する主軸１と、該主軸１に対向する対向軸と、前記主軸１に把持された材料から予め定められた形状の製品を加工する製品加工手段とを備え、前記主軸１に把持された材料の端部を支持する支持具１６を前記対向軸に装着し、前記材料を、前記支持具１６によって支持して前記製品に加工する工作機械において、前記主軸１に把持された材料の先端部分に、支持具加工用の支持具加工部１７を設け、該支持具加工部１７を前記材料から突っ切り、前記対向軸に受け渡す支持具加工部受渡し手段と、前記対向軸に把持された前記支持具加工部１７を加工して前記支持具１６を製作する支持具加工手段とを設け、前記製品加工手段が、前記支持具加工部１７が突っ切られた材料を、前記支持具１６によって支持して加工するように構成されたことを第１の特徴とする。   A machine tool according to the present invention for solving the above-described problems has a main shaft 1 for gripping a material for processing, an opposing shaft facing the main shaft 1, and a shape predetermined from the material gripped by the main shaft 1. A product processing means for processing the product, and a support tool 16 that supports an end of the material gripped by the main shaft 1 is mounted on the opposing shaft, and the material is supported by the support tool 16 to support the product. In the machine tool to be machined, a support tool processing section 17 for processing the support tool is provided at the tip portion of the material gripped by the main shaft 1, and the support tool processing section 17 is cut off from the material and received by the opposing shaft.

第２に、前記主軸１に把持された材料を、前記対向軸に把持させて受け渡す材料受渡し手段と、前記支持具１６を前記対向軸から排出させる支持具排出手段１４とを設け、前記製品加工手段が、前記主軸１での前記材料の加工完了後、前記支持具１６を前記対向軸から排出させ、前記対向軸に前記主軸１から前記加工済みの一次製品を受け渡し、前記対向軸での２次加工を実行するように構成されたことを特徴とする。   Second, there is provided a material delivery means for delivering the material gripped by the main shaft 1 while gripping the material to the opposing shaft, and a support tool discharging means 14 for discharging the support tool 16 from the opposing shaft. After the processing of the material on the main shaft 1 is completed, the processing means discharges the support 16 from the opposing shaft, delivers the processed primary product from the main shaft 1 to the opposing shaft, It is configured to perform secondary processing.

第３に、前記主軸１に対向する２次加工用の第２主軸３を備え、前記対向軸が前記第２主軸３からなることを特徴とする。   Thirdly, a second main shaft 3 for secondary processing that opposes the main shaft 1 is provided, and the counter shaft is composed of the second main shaft 3.

第４に、前記材料が、複数の製品を加工することができる長尺の棒材９からなることを特徴とする。   4thly, the said material consists of the elongate bar 9 which can process a some product.

上記課題を解決するための本発明の材料の加工方法は、主軸に把持された材料の先端部
分を、主軸１に把持された材料の端部を支持する支持具用の支持具加工部１７として突っ切って、前記主軸１に対向する対向軸に受け渡し、前記対向軸に把持された支持具加工部１７を前記支持具１６に加工し、前記支持具加工部１７が突っ切られた前記主軸１側の材料を、該主軸１で把持し、前記対向軸の支持具１６で支持して加工することを第１の特徴とする。 In the material processing method of the present invention for solving the above-described problem, the tip portion of the material gripped by the main shaft is used as a support tool processing portion 17 for a support tool that supports the end of the material gripped by the main shaft 1. Cut off, passed to the opposite shaft opposite to the main shaft 1, processed the support tool processing portion 17 gripped by the opposite shaft into the support tool 16, and the main shaft 1 side where the support tool processing portion 17 was cut off The first feature is that the material is gripped by the main shaft 1 and supported by the support tool 16 of the opposed shaft.

第２に、前記支持具加工部１７が突っ切られた材料の主軸１での加工完了後、前記支持具１６を前記対向軸から排出し、前記主軸１の加工済みの一次製品を、前記対向軸に受け渡して、該対向軸に把持させ、前記対向軸で加工することを特徴とする。   Second, after the processing of the material cut through the support tool processing portion 17 in the main shaft 1 is completed, the support tool 16 is discharged from the counter shaft, and the processed primary product of the main shaft 1 is transferred to the counter shaft. It is transferred to a shaft, gripped by the opposite shaft, and processed by the opposite shaft.

第３に、前記支持具１６を対向軸に一度支持させた後は、前記主軸１に把持された材料を連続的に前記支持具１６に支持させて、連続的に製品加工を行うことを特徴とする。   Third, after the support tool 16 is once supported by the opposing shaft, the material gripped by the main shaft 1 is continuously supported by the support tool 16 and product processing is continuously performed. And

以上のように構成される本発明の構造によると、材料を支持具によって支持して加工を行うことにより、材料を安定して、高精度に加工することができるだけでなく、支持具が対向軸に把持されて製造されるため、材料の加工前に予め支持具を準備する必要がなく前記加工を容易に行うことができるという効果がある。   According to the structure of the present invention configured as described above, it is possible not only to process the material stably and with high accuracy by supporting the material with the support tool, but also to support the material with the opposing shaft. Therefore, there is an effect that the processing can be easily performed without preparing a support in advance before processing the material.

また前記主軸での加工後に、加工済みの材料を対向軸に受け渡し、対向軸で２次加工を行う場合は、前記主軸に把持された材料を、前記対向軸に把持させて受け渡す材料受渡し手段と、前記支持具を前記対向軸から排出させる支持具排出手段とを設け、前記製品加工手段を、前記主軸での前記材料の加工完了後、前記支持具を前記対向軸から排出させ、前記対向軸に前記主軸から前記加工済みの一次製品を受け渡し、前記対向軸での２次加工を実行するように構成することによって、支持具の支持台と２次加工用の主軸を対向軸で兼用することができる。   In addition, when the processed material is transferred to the opposing shaft after the processing with the main shaft and the secondary processing is performed with the opposing shaft, the material transfer means for transferring the material gripped on the main shaft to the opposing shaft. And a support tool discharging means for discharging the support tool from the opposing shaft, and after the processing of the material on the main shaft is completed, the product processing means discharges the support tool from the opposing shaft, and By passing the processed primary product from the main shaft to the shaft and performing the secondary processing on the opposed shaft, the supporting base of the support tool and the main shaft for secondary processing are shared by the opposed shaft. be able to.

これにより加工上の制約の発生を抑制し、簡単な構造で支持具によって材料を支持しながら加工を行うことができるとともに、従来２次加工用の第２主軸が設けられている工作機械の場合、前記第２主軸を対向軸とすることによって、構成を変更することなく前記加工を行うことが可能となり、特殊で高価な設備が不要となる等の効果がある。   In the case of a machine tool that suppresses the occurrence of machining restrictions, can be machined with a simple structure while supporting the material with a support tool, and is conventionally provided with a second spindle for secondary machining By using the second main shaft as an opposing shaft, the processing can be performed without changing the configuration, and there is an effect that a special and expensive facility is not required.

また材料として、複数の製品を加工することができる長尺の棒材を使用することによって、特に２次加工が必要な場合は、対向軸で前記支持具と前記一次製品とを交互に把持して、連続的に製品を加工することができる。なお２次加工が不要な場合は、１本の棒材の１回目の加工に際して、該棒材から支持具を製造することによって、その後連続的に高精度で製品を加工することができる。   In addition, by using a long bar that can process a plurality of products as materials, especially when secondary processing is required, the support tool and the primary product are alternately held by the opposed shaft. The product can be processed continuously. When secondary processing is unnecessary, a product can be processed continuously with high accuracy by manufacturing a support from the bar during the first processing of one bar.

By moving the second headstock 4 in the X3 axis direction, both the main shafts 1 and 3 can be arranged to face each other so that their axis centers coincide. On both opposing surfaces of the main spindles 1 and 3, chucks that respectively hold the processing material are provided so as to be openable and closable.

前記第１主軸台２の対向側には、前記第１主軸１の軸線方向（Ｚ１軸方向）に平行なＺ２軸方向及び該Ｚ２軸方向に水平方向に直交するＸ２軸方向に移動自在に第１刃物台７が設けられている。本実施形態において、該第１刃物台７は、タレット刃物台からなり、前記第１主軸１に把持される材料を加工する加工工具が複数装着されている。前記第２主軸台４の対向側には、第２刃物台８が固定的に設けられている。前記第２刃物台８には、前記第２主軸３に把持される材料を加工する加工工具が複数装着されている。   On the opposite side of the first headstock 2, the first main shaft 1 is movable in the Z2 axis direction parallel to the axial direction (Z1 axis direction) of the first main shaft 1 and in the X2 axis direction perpendicular to the Z2 axis direction. A one tool post 7 is provided. In the present embodiment, the first tool post 7 is composed of a turret tool post, and a plurality of processing tools for processing the material gripped by the first main spindle 1 are mounted thereon. A second tool post 8 is fixedly provided on the opposite side of the second head stock 4. A plurality of processing tools for processing the material gripped by the second main spindle 3 are mounted on the second tool post 8.

本自動旋盤には、加工用の材料として第１主軸１の後端から、従来公知のバーフィーダ等によって長尺の棒材９が供給される。該棒材９は、図２（Ａ）に示されるように、前記第１主軸１の先端から所定長さ突出して、前記チャック１１によって前記第１主軸１に把持される。本自動旋盤は、図２（Ｂ）に示されるように、前記棒材９の第１主軸１から突出した部分を、第１主軸１の回転及び第１刃物台７のＺ２軸方向とＸ２軸方向の移動により、前記第１刃物台７に装着された加工工具７Ａで加工することができる。   The automatic lathe is supplied with a long bar 9 from the rear end of the first spindle 1 as a processing material by a conventionally known bar feeder or the like. As shown in FIG. 2A, the bar 9 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 11. As shown in FIG. 2 (B), the automatic lathe has a portion protruding from the first main shaft 1 of the bar 9 as the rotation of the first main shaft 1 and the Z2 axis direction of the first tool post 7 and the X2 axis. By the movement of the direction, it can be processed by the processing tool 7A mounted on the first tool post 7.

前記第２主軸３は、図２（Ｃ）に示されるように、前記第２主軸台４のＺ３軸方向の移動によって、前記第１主軸１に把持された棒材９の先端部分が前記チャック１２に挿入されるように、第１主軸１に向かってＺ３軸方向に移動することができる。図３（Ａ）に示されるように、本自動旋盤は、第１主軸１に把持された棒材９の先端部分が第２主軸３に挿入された状態で、第２主軸３のチャック１２を閉じ、突切りバイト１３で棒材９を突っ切ることによって、第１主軸１で加工された棒材９の一部を材料として第２主軸３に受け渡すことができる。   As shown in FIG. 2C, the second spindle 3 has the tip portion of the bar 9 gripped by the first spindle 1 by the movement of the second spindle stock 4 in the Z3 axis direction. 12 can be moved in the Z3 axis direction toward the first main shaft 1. As shown in FIG. 3A, the automatic lathe is configured so that the chuck 12 of the second main spindle 3 is inserted in a state where the tip portion of the bar 9 gripped by the first main spindle 1 is inserted into the second main spindle 3. By closing and cutting off the bar 9 with the parting tool 13, a part of the bar 9 processed by the first main shaft 1 can be transferred to the second main shaft 3 as a material.

前記第２主軸３で把持した材料は、前記第２主軸台４のＸ３軸方向及びＺ３軸方向の移動によって、図３（Ｂ）に示されるように、前記第２刃物台８に装着された加工工具８Ａで加工することができる。前記第２主軸３内には棒状のノックアウト手段（ノックアウト棒）１４が、第２主軸３の軸線方向に進退移動自在に装着されている。前記第２主軸３の材料の把持を解除し、該ノックアウト手段１４を第２主軸３の先端に向けて移動させることによって、前記第２主軸３の材料を排出することができる。   The material gripped by the second spindle 3 was mounted on the second tool rest 8 as shown in FIG. 3B by the movement of the second spindle stock 4 in the X3 axis direction and the Z3 axis direction. It can be processed with the processing tool 8A. A rod-shaped knockout means (knockout rod) 14 is mounted in the second main shaft 3 so as to be movable back and forth in the axial direction of the second main shaft 3. By releasing the gripping of the material of the second main shaft 3 and moving the knockout means 14 toward the tip of the second main shaft 3, the material of the second main shaft 3 can be discharged.

本自動旋盤には、前記両刃物台７，８及び第２主軸台４の移動や両主軸１，３の回転等を制御する制御装置１０が設けられている。該制御装置１０は、内蔵されるプログラムによって、前記棒材９から予め定められた形状の製品を加工する製品加工手段として機能する。   The automatic lathe is provided with a control device 10 for controlling the movement of the two tool rests 7 and 8 and the second spindle stock 4 and the rotation of the two spindles 1 and 3. The control device 10 functions as a product processing means for processing a product having a predetermined shape from the bar 9 by a built-in program.

前記製品加工手段は、図４のフローチャートに示されるように、ステップＳ１で、前記棒材９から前記製品を加工する際に、前記第１主軸１に把持された棒材９を支持する支持具１６を加工し、次にステップＳ２で、前記第２主軸３に把持された前記支持具１６を使用して前記棒材９を第１主軸１で加工（１次加工）する。次にステップＳ３で、前記第２主軸３から前記支持具１６を排出し、ステップＳ４で、前記ステップＳ２で加工された棒
材９の一部を一次製品として第２主軸３に受け渡し、該一次製品を材料として第２主軸で加工（２次加工）する。 As shown in the flowchart of FIG. 4, the product processing means supports the bar 9 gripped by the first main shaft 1 when processing the product from the bar 9 in step S <b> 1. 16 is processed, and then in step S2, the bar 9 is processed (primary processing) with the first main shaft 1 using the support 16 held by the second main shaft 3. Next, in step S3, the support 16 is discharged from the second main spindle 3, and in step S4, a part of the bar 9 processed in step S2 is delivered to the second main spindle 3 as a primary product. Machining (secondary machining) with the second spindle as a material.

前記一次製品の第２主軸３への受け渡しは、前記のように第２主軸３のＺ３軸方向への移動と、第１主軸１及び第２主軸３のチャック１１，１２の開閉と、突切りバイト１３の作動によって行われ、この際前記制御装置１０は、プログラムによって材料受渡し手段として機能する。前記ステップＳ４の加工によって前記製品が完成するため、製品（完成品）を回収し、ステップＳ５で加工個数を確認し、必要な個数に達するまで、上記ステップＳ１からＳ４を繰り返す。   As described above, the primary product is transferred to the second main shaft 3 by moving the second main shaft 3 in the Z3 direction, opening and closing the chucks 11 and 12 of the first main shaft 1 and the second main shaft 3, and parting off. The control device 10 functions as a material delivery means according to a program. Since the product is completed by the processing in step S4, the product (finished product) is collected, the number of processed products is confirmed in step S5, and the above steps S1 to S4 are repeated until the required number is reached.

本自動旋盤は以上のように製品加工手段によって製品の加工を行うため、１つの製品を加工するために必要な棒材９の長さは、ステップＳ１で行う加工に必要な長さ（支持具１６の加工に必要な長さ）とステップＳ２及びＳ４で行う加工に必要な長さ（製品の加工に必要な長さ）との和となる。   Since this automatic lathe processes the product by the product processing means as described above, the length of the bar 9 necessary for processing one product is the length required for the processing performed in step S1 (support tool). 16) and the length required for processing performed in steps S2 and S4 (length required for processing the product).

このため１つの製品を加工するための棒材９の先端部分は、図２に示されるように、前記支持具加工用の支持具加工部１７を構成する。本実施形態では、１つの製品を加工するために必要な棒材の長さに対して十分に長尺な棒材を本自動旋盤に供給し、１本の棒材から複数の製品を加工するように構成されている。   For this reason, the front-end | tip part of the bar 9 for processing one product comprises the support tool processing part 17 for the said support tool processing, as FIG. 2 shows. In the present embodiment, a sufficiently long bar material is supplied to the automatic lathe for processing a single product, and a plurality of products are processed from one bar material. It is configured as follows.

前記ステップＳ１における支持具１６の加工は、まず図２（Ｂ）に示されるように、第１主軸１に把持された棒材９の支持具加工部１７の先端から所定長さを、第２主軸３のチャック１２に把持されるサイズに外径切削加工を行う。次に図２（Ｃ），図３（Ａ）に示されるように、支持具加工部１７を棒材９から突っ切り第２主軸３に受け渡す。前記ステップＳ１の加工プログラムによって前記制御装置１０は支持具加工手段として機能し、支持具加工部１７から支持具１６を製作する。   As shown in FIG. 2 (B), the processing of the support 16 in the step S1 is performed by setting a predetermined length from the tip of the support processing unit 17 of the bar 9 held by the first main shaft 1 to a second length. The outer diameter is cut to a size that is held by the chuck 12 of the main shaft 3. Next, as shown in FIG. 2C and FIG. 3A, the support tool processing portion 17 is cut off from the bar 9 and transferred to the second main shaft 3. The control device 10 functions as a support tool processing means according to the processing program in step S 1, and manufactures the support tool 16 from the support tool processing unit 17.

この際前記制御装置１０が材料受け渡し手段として機能し、第１主軸１で加工済みの支持具加工部１７を材料として第１主軸１から第２主軸３に受け渡す。つまり該材料受け渡し手段が、支持具加工部１７を前記棒材９から突っ切り、前記第２主軸３に受け渡す支持具加工部受渡し手段を兼用する。次に図３（Ｂ）に示されるように、第２主軸３で支持具加工部１７の先端を加工してテーパ状に尖らせ、支持具１６の加工を完了する。支持具１６は、第２主軸３に把持された状態で加工され、製造される。   At this time, the control device 10 functions as a material transfer means, and transfers the support tool processing portion 17 processed by the first main shaft 1 from the first main shaft 1 to the second main shaft 3 as a material. That is, the material transfer means also serves as a support tool processing portion transfer means for cutting the support tool processing portion 17 from the bar 9 and transferring it to the second main shaft 3. Next, as shown in FIG. 3 (B), the tip of the support tool processing portion 17 is processed by the second main shaft 3 so as to be tapered, and the processing of the support tool 16 is completed. The support 16 is processed and manufactured while being gripped by the second spindle 3.

前記ステップＳ２の１次加工は、まず図５（Ａ）に示されるように、第１主軸１に把持された棒材９の先端中心に凹部１８を加工し、次に図５（Ｂ）に示されるように、前記棒材９を製品の加工に必要な長さ突出させ、支持具１６の先端が凹部１８に収容当接するように、第２主軸３をＺ３軸方向に移動させ、第１主軸１に把持された棒材９の先端を支持具１６によって回転自在に支持する。次に図５（Ｃ）に示されるように、前記棒材９を支持具１６によって支持した状態で、第１刃物台７の加工工具７Ａによって所定の形状に加工する。これにより一次製品が加工される。   In the primary processing in step S2, first, as shown in FIG. 5A, the recess 18 is processed in the center of the tip of the bar 9 gripped by the first main shaft 1, and then in FIG. 5B. As shown in the drawing, the bar 9 is projected for a length necessary for processing the product, and the second main shaft 3 is moved in the Z3 axis direction so that the tip of the support 16 is accommodated and abutted on the recess 18. The tip of the bar 9 held by the main shaft 1 is rotatably supported by the support 16. Next, as shown in FIG. 5C, in a state where the bar 9 is supported by the support 16, it is processed into a predetermined shape by the processing tool 7 </ b> A of the first tool post 7. As a result, the primary product is processed.

ステップＳ２での１次加工は、前記棒材９の先端が支持具１６によって支持されているため、前記棒材９の第１主軸１からの突出長さが比較的長い場合であっても、安定して加工を行うことができ、高精度の加工を行うことができる。   In the primary processing in step S2, since the tip end of the bar 9 is supported by the support 16, even if the protruding length of the bar 9 from the first main shaft 1 is relatively long, Processing can be performed stably, and high-precision processing can be performed.

特に支持具１６は第２主軸３に把持されて製造されるため高精度であり、且つ支持具１６の軸線と前記両主軸１，３の軸線とが高精度で一致するため、ステップＳ２での加工精度がより向上する。また前記１次加工に際して予め支持具を作製して準備しておく必要がないため、上記加工を容易に行うことができる。   In particular, since the support 16 is manufactured by being gripped by the second main shaft 3, the axis of the support 16 and the axes of the two main shafts 1 and 3 coincide with each other with high accuracy. Processing accuracy is further improved. Further, since it is not necessary to prepare and prepare a support in advance during the primary processing, the processing can be easily performed.

前記ステップＳ３の支持具１６の排出は、図６に示されるように、前記支持具１６と前記棒材９とが離反するように第２主軸をＺ３軸方向に移動させ、前記ノックアウト棒１４を第２主軸３の先端に向かって移動させ、第２主軸３のチャック１２を開くことによって、支持具１６を第２主軸３の先端から押し出して排出を行う。前記ノックアウト棒１４は、前記支持具１６を前記第２主軸２から排出させる支持具排出手段を構成している。   As shown in FIG. 6, the discharge of the support 16 in step S3 is performed by moving the second main shaft in the Z3 axis direction so that the support 16 and the bar 9 are separated from each other. By moving toward the tip of the second spindle 3 and opening the chuck 12 of the second spindle 3, the support 16 is pushed out from the tip of the second spindle 3 and discharged. The knockout bar 14 constitutes a support discharging means for discharging the support 16 from the second main shaft 2.

前記ステップＳ４の２次加工は、まず前記制御装置１０を材料受け渡し手段として機能させ、図７（Ａ），（Ｂ）に示されるように、前記一次製品９’（第１主軸１で加工が完了した棒材９の一部）を突っ切り、第２主軸３に材料して受け渡す。なお該一次製品９’の受け渡しは、前記同様であるため詳細な説明は割愛する。次に図７（Ｃ）に示されるように、前記一次製品９’に第２刃物台８の加工工具８Ａにより所定の加工を行い、製品加工を完了し、図８に示されるように、前記ノックアウト棒１４によって製品回収を行う。   In the secondary processing in step S4, first, the control device 10 is made to function as a material delivery means, and as shown in FIGS. 7A and 7B, the primary product 9 ′ (processing by the first main spindle 1) is performed. A part of the completed bar 9 is cut off and delivered to the second spindle 3 as a material. Since the delivery of the primary product 9 'is the same as described above, a detailed description is omitted. Next, as shown in FIG. 7 (C), the primary product 9 ′ is subjected to predetermined processing with the processing tool 8A of the second tool post 8 to complete the product processing, and as shown in FIG. The product is collected by the knockout bar 14.

以上のように第２主軸３に棒材９の先端を支持する支持具１６を設けて第１主軸１での加工（１次加工）を行うため、心押し台や支持具１６を保持する支持具専用の支持台等の特殊で高価な特別な機構や設備が不要であり、簡単に材料の端部を支持して安定して高精度に加工を行うことができる。   As described above, the support 16 that supports the tip of the bar 9 is provided on the second main shaft 3 to perform processing (primary processing) on the first main shaft 1, so that the support for holding the tailstock and the support 16 is held. Special and expensive special mechanisms and equipment such as a support stand dedicated to the tool are not required, and the end portion of the material can be easily supported and processed stably with high accuracy.

また１つの製品を加工する際に、該製品の加工に使用する支持具１６を製品加工毎に製造し、２次加工（第２主軸３での加工）前に、第２主軸３から排出するように構成することによって、２次加工が必要な製品を加工する場合も、加工上の制約の発生を抑制し、心押し台等の特別な機構を設けることなく、第２主軸３を使用して連続的に材料の端部を支持して前記加工を行うことができる。   Further, when processing one product, the support 16 used for processing the product is manufactured every time the product is processed, and discharged from the second main shaft 3 before the secondary processing (processing by the second main shaft 3). With this configuration, even when processing a product that requires secondary processing, the second spindle 3 is used without suppressing processing restrictions and without providing a special mechanism such as a tailstock. Thus, the processing can be performed by continuously supporting the end of the material.

なお前記ステップＳ１において、前記支持具加工部１７の先端部分の外形切削加工を行い、支持具加工部１７の第２主軸３に把持される部分の径を、前記ステップＳ４での加工を行う際に、前記一次製品９’の第２主軸３に把持される部分の径と同一にすることによって、第２主軸３のチャック１２を交換することなく、連続的に支持具１６と前記一次製品９’の第２主軸３での把持を交互に行うことができる。   In step S1, when the outer end of the support tool processing portion 17 is subjected to external cutting and the diameter of the portion gripped by the second spindle 3 of the support tool processing portion 17 is processed in step S4. Further, by making the diameter of the portion gripped by the second main shaft 3 of the primary product 9 ′ continuous, the support 16 and the primary product 9 can be continuously replaced without replacing the chuck 12 of the second main shaft 3. It is possible to alternately perform gripping on the second main spindle 3.

また前記支持具１６は製品と同一の材料（棒材９）から製造されるため、前記１次加工時の支持が安定するほか、排出された支持具１６を切削屑とともに処理することができ、支持具１６の処理を容易に行うこともできる。   In addition, since the support 16 is manufactured from the same material (bar material 9) as the product, the support at the time of the primary processing is stabilized, and the discharged support 16 can be treated together with cutting waste. The support 16 can be easily processed.

本実施形態では、２次加工を行う場合について説明したが、２次加工が不要な場合は、棒材９の先端を支持具加工部とし、１本の棒材の１回目のみ支持具１６を加工して第２主軸３に設けることによって、当該支持具１６を連続的に使用することで、棒材９から複数の製品を加工することができる。この場合も支持具１６を第２主軸３で加工することによって予め支持具を準備する必要がなく、簡単な構成で材料を支持し、高精度な加工等を行うことができる。   In the present embodiment, the case where the secondary processing is performed has been described. However, when the secondary processing is unnecessary, the tip of the bar 9 is used as the support tool processing portion, and the support 16 is only attached to the first time of one bar. By processing and providing the second main shaft 3, a plurality of products can be processed from the bar 9 by continuously using the support 16. Also in this case, it is not necessary to prepare a support tool in advance by processing the support tool 16 with the second main shaft 3, and the material can be supported with a simple configuration, and high-precision processing or the like can be performed.

また本実施形態では、第２主軸３を、第１主軸１に対向する対向軸として、支持具１６の把持を行う例について説明したが、第２主軸３を有さない自動旋盤の場合は、前記第１主軸１に対向し、前記第２主軸と同様に、前記支持具１６の加工を行うことができる対向軸を設けることによって、本発明の自動旋盤とすることができる。ただし第２主軸３を有する自動旋盤の場合は、自動旋盤の構成を特に変更することなく、本発明の自動旋盤とすることができる。   Further, in the present embodiment, an example in which the support 16 is gripped using the second main shaft 3 as an opposed shaft facing the first main shaft 1 has been described. However, in the case of an automatic lathe that does not have the second main shaft 3, The automatic lathe of the present invention can be provided by providing an opposing shaft that faces the first main shaft 1 and can process the support 16 in the same manner as the second main shaft. However, in the case of an automatic lathe having the second spindle 3, the automatic lathe of the present invention can be obtained without changing the configuration of the automatic lathe.

なお上記実施形態では、第１主軸台２がベッド６上でＺ１軸方向に一体的に固定されて
いる例について説明したが、前記第１主軸台２を、前記Ｚ１軸方向に移動自在に設け、前記第１主軸１の対向側に、ガイドブッシュを設けたいわゆるガイドブッシュ型旋盤とすることもできる。 In the above embodiment, the example in which the first headstock 2 is integrally fixed on the bed 6 in the Z1 axis direction has been described. However, the first headstock 2 is provided to be movable in the Z1 axis direction. A so-called guide bush type lathe provided with a guide bush on the opposite side of the first main shaft 1 can also be used.

この場合第１主軸１（第１主軸台２）がＺ１軸方向に移動するため、第２主軸３（第２主軸台４）をＺ２軸方向に、第１主軸１と同期して移動させることによって、第１主軸に把持される材料の先端を、支持具１６で支持しながら、ガイドブッシュを使用して１次加工等を行うことができる。   In this case, since the first spindle 1 (first spindle stock 2) moves in the Z1 axis direction, the second spindle 3 (second spindle stock 4) is moved in the Z2 axis direction in synchronization with the first spindle 1. Thus, primary processing or the like can be performed using the guide bush while the tip of the material gripped by the first spindle is supported by the support 16.
