The indexing means 7 is arranged on the head 1 outside the V block 5-2, and on the center of the workpiece 8 positioned by the V blocks 5-1 and 5-2, and is shown in FIG. As described above, the workpiece 8 is attached to the index 7-1, and a predetermined indexing hole position is set on the end side surface of the workpiece 8 together with the clamp attached to the bed 1.

Reference numeral 9 is a tool supporting portion, 9-1 and 9-2 are handles, 10 is a drilling tool (electric drill), and 10-1 is a drill. The tool support portion 9 faces the side surface of the V block 5-1 on the bed 1 with a distance laterally of the V block 5-1 and its height can be freely adjusted by a known means with a handle 9-1. Further, the head portion 9-3 of the tool supporting portion 9 is provided with a horizontally movable tool for drilling, that is, an electric drill having a mountable drill 10-1.

11 is a clamp means, 11-1 is a handle, and 11-2 is a retainer. The clamp means 11 is attached to the bed 1,
A known tool is used in which the holding tool 11-2 holds the peripheral surface of the workpiece 8 and clamps it by pulling the handle 11-1 toward you.
