ねばならなかった。In a general-purpose milling machine for machining round holes, as shown in FIG. 1, a boring device 2 is attached to the main shaft 1 of the milling machine, and a cutting tool 3 is attached to the boring device. A vise 5 is installed on the table 4 for this cutter 5, and the vise 5 is made to grip a workpiece 6 to be machined into a round hole, and the cutter 5 is
The inner diameter of the round holes is measured using a cylinder gauge 10, as shown in FIG.
is larger than the gap L1 between the upper surface of the workpiece 6 and the cutting tool 3, so the cylinder gauge 10 is connected to the cutting tool 3 and the boring device 2.
ft. could not be inserted into the round hole 7 due to contact with the ft.
o For this purpose, the table 4 was moved by rotating the handle 11, and the cylinder gauge 10 was inserted into the round holes 7, 8, 9 to measure the inner diameter. After this measurement is completed, the cutting tool S is returned to the position of the round hole 7, but since it is a general-purpose milling machine, it lacks reproducibility, so the boring device 2 is rotated to make the sound of the cutting tool 5 and the round hole 7 uniform. I had to move table 4 so that
