The same members are designated by the same reference numerals and description thereof will be omitted.

That is, a plurality of suction members 133 are embedded at appropriate positions on the vise reference surface 15 of the reference vise 13 on the fixed side of the reference vise apparatus 11. The suction member 133 may be, for example, a magnet or a vacuum suction pad. Therefore, the effect can be the same as that of the first embodiment.

FIG. 8 and FIG. 9 show a fourth embodiment of the present invention. The point different from the first embodiment is the restraint means provided on the reference vice, which is different from the first embodiment. The same members are designated by the same reference numerals and description thereof will be omitted.

That is, at the lower part of the reference vise 13 on the fixed side of the reference vise device 11, a support portion 135 which projects from the vise reference surface 15 of the reference vise 13 and supports the workpiece W _s is provided. A fluid pressure actuated cylinder 137 is provided in a vertical state on the upper portion as a driving member, and a holding member 141 is integrally provided at the tip of a piston rod 139 of the cylinder 137.

The difference from the first embodiment is the restraint means provided on the reference vice, which is different from the first embodiment. The same members are designated by the same reference numerals and the description thereof will be omitted.

That is, at the lower portion of the reference vise 13 on the fixed side of the reference vise apparatus 11, an L-shaped guide member 144 for guiding the flange portion F of the H-shaped steel, which is the workpiece W _s , is attached to the bolt 145. It was fixed and configured. Note that the guide member 143 may be configured so as to be escaped by, for example, a cylinder or the like, as shown by a chain double-dashed line in FIG. Therefore, the effect can be the same as that of the first embodiment.

FIG. 12 and FIG. 13 show a sixth embodiment of the present invention. The difference from the first embodiment is that the work to be cut remains fixed by the moving side vise at the time of turning back. The same members as those in the first embodiment are denoted by the same reference numerals in that they are returned by turning, and the description thereof will be omitted.

That is, the moving-side vise 85 provided on the swivel base body 5 has a cylinder 87 fixed to the swivel base body 5 and a work pressing member 91 swingably attached to the tip of a piston rod 89 of the cylinder 87. It is constructed by being pivotally attached.

As an operation, as shown in FIG. 12, when the workpiece W _s to be cut is angle-cut, the cylinder 87 as the moving side vise 85 is operated on the vise reference surface 15 of the reference vise 13. The work W _s is pressed and fixed to the vise reference surface 15 by the work pressing member 91. Further, since the right angle cutting is performed after the end of the angle cutting, even when the turning base body 5 is turned, the moving side vice 85 turns while holding the workpiece W _s to be cut. (In the drawing of FIG. 12, the return swing is shown by an arrow, and the position of the work pressing member 91 at the end of the swing is shown by a chain double-dashed line.)
