ることにより、各工具を順次割出し、位置決めして加工
する技術が実現されている。In recent years, in No. lathes, a transfer robot that transfers the workpiece is placed adjacent to the lathe body, and the workpiece transferred by this transfer robot is gripped and rotated by a power chuck, and the other hand is placed on the tool rest. Multiple cutting tools are installed in advance, and by rotating the tool post (turret tool post) or moving it horizontally (<shi-made tool post), each tool can be indexed and positioned in sequence. The processing technology has been realized.

ところで鍛近、省力化等の要請から、この種のＮｏ旋盤
にめっては、人手をわずられすことなく長時間に亘って
自動的に加工を行う無人化の要望が高まってきている。By the way, due to demands for forging, labor saving, etc., there is an increasing demand for unmanned lathes that can perform processing automatically over long periods of time without requiring manual labor. .

ところが、上述したようなＮｏ旋盤にあっては、刃物台
に予め装着し得る切削工具はせいぜいｌｏ数本どまりで
あり、予め、寿命に達した工具、或いは欠損した工具に
対する代替用工具を多数本準備して装着することがむず
かしくこのため長時間の無人化が困難であった。However, in the above-mentioned No. lathe, the number of cutting tools that can be pre-installed on the tool rest is at most a few, and many replacement tools for tools that have reached the end of their service life or are missing are installed in advance. It was difficult to prepare and install it, making it difficult to leave it unattended for long periods of time.

でいる。Therefore, as in machining centers, for example, there is a technology in which a lathe body is equipped with a tool magazine that can store a large number of cutting tools, and a dedicated tool exchange device that exchanges cutting tools between the tool magazine and the turret. It has been developed. However, when such a tool changer is attached, the space in the lathe body is narrowed, which limits the size of workpieces that can be machined.In addition, the installation of the tool changer increases manufacturing costs. This is hindering its spread.
