That is, the present invention forms a first bracket (100) for fixing the multi-stage antenna structure sliding cylinder 90 to the lower carrier support 51 that is inside the cutting space, the lower carrier 50 is transported It is possible to move like a multi-stage antenna structure sliding cylinder 90, and to form a second bracket 110 on the right side of the non-cutting space to serve to fix the multi-stage antenna structure sliding cylinder (90).

Looking at the operation of the present invention configured as described above are as follows.

The machine tool of the present invention uses the first spindle 20, the second spindle 30, the upper tool rest 40, and the lower tool rest 50 on the first spindle 20 and the second spindle 30. Process the interlocking workpiece.

At this time, the upper tool bar 40 and the lower tool bar 50 processes the workpiece while moving in the Z1 axis and Z2 axis direction, in particular, since the working area of the Z2 axis is located inside the cutting space, it concentrates on chips or cutting oil at the bottom. Exposed.

In the present invention, the first tool bracket 100 and the second bracket 110 are installed on the lower tool rest supporter 51 and the partition 60, and one end of the first bracket 100 and the second bracket 110 is installed.
