2. Description of the Related Art Conventionally, a workpiece is machined by a lathe with a sub-spindle which is relatively large in a machining factory. When processing a work with such a lathe, the work is gripped by the chuck on the headstock side, and the processing tool is gripped by the chuck on the sub spindle side.
In this state, the chuck on the headstock side is rotated while the sub-spindle is advanced by manual feed of the handle, and this is performed (for example, as disclosed in Japanese Patent No. 2885475).

[0003]

However, in the above-mentioned lathe, the center on the headstock side and the center on the sub-spindle side are already 3/100 mm when the lathe is manufactured.
There is a problem that when the machining is repeated, the slide base is worn and the above error is further enlarged, the machining accuracy is deteriorated, and frequent calibration is required. In addition, when changing tools, it is necessary to change the tool with the sub-spindle separated from the headstock to some extent because there is a turret in front of the tool. There is a problem that it is lost. Further, as described above, since it is necessary to move the sub spindle forward and backward to the headstock side by hand-feeding the handle at the time of processing, it takes time until processing,
There is a problem that the types of work that can be processed by the lathe are also limited.

On the other hand, a drilling machine, a milling machine, and the like are installed in a processing factory in addition to a lathe. In the processing factory, various processings are performed by properly using these processing apparatuses.
When the number of machining devices is limited and the number of workpieces is large and the machining schedule is strict, for example, when performing hexagonal chamfering of bolt heads etc., the load is concentrated on the person in charge of the milling machine. There was a problem to do. Therefore, the present invention provides a general-purpose processing jig capable of sharing a part of operations of a lathe, a milling machine, and a drilling machine which are arranged in a relatively large number of processing plants while improving the processing accuracy, and a processing method using the same.
