<p>PROBLEM TO BE SOLVED: To provide a machine tool that can have a different kind of tool mounted on the same tool mounting body to decrease the number of components, and is good in convenience since a user need not change the tool mounting body as processing steps and processing conditions change and only replaces a tool on the processing spot.SOLUTION: A tool mounting body 4 includes an annular part 41, an arbor 42, a pull stud 43, a plate fitting part, and a sleeve fitted inside the plate fitting part. A rotation stop plate 5 includes a fitting hole where the plate fitting part is fitted, a hand reeling hole part formed on the reverse side of the fitting hole, a screw insertion hole 52 into which a screw is inserted, and a pin insertion hole 55. A tool retainer 6 includes a shaft fitting hole in which a shaft part is fitted, a female screw, and a holding hole for holding a tool 7. After the rotation stop plate 5 is threadably engaged with the tool mounting body 4 with the plate fitting part fitted in the fitting hole, the screw 81 is inserted into the screw insertion hole 52 and screwed in the female screw so as to fit the tool retainer 6 to the tool mounting body 4.</p> |
