ガイド部が当接している部位は切削されず、回転刃が被
加工物にくい込んで余分に切削することを防止すること
ができる。Therefore, when the rotary blade is rotated and brought into contact with the workpiece, the part that the blade is in contact with will be cut;
The portion that the guide portion is in contact with is not cut, and it is possible to prevent the rotary blade from digging into the workpiece and cutting it excessively.
〈実施例〉 以下、この発明の実施例を図面に基づいて説明する。<Example> Embodiments of the present invention will be described below based on the drawings.
第１〜４図に示した第１実施例の回転刃１１は、従来と
略同様に、縦条の刃部１３が形成される略円筒状の本体
部１２の下側から連結部１４が突設されて構成されてい
る。The rotary blade 11 of the first embodiment shown in FIGS. 1 to 4 has a connecting portion 14 protruding from the lower side of a generally cylindrical main body portion 12 in which a vertical blade portion 13 is formed, in substantially the same manner as the conventional one. established and configured.

。A U-shaped notch 13a is partially formed on the outer periphery of the blade portion 13 of the first embodiment, and a wire 16 such as a wire is engaged with this notch 13a and wound spirally. It is attached. The wire rod 16 is provided so as to be flush with the outer periphery of the blade portion 13, and the location where the wire rod 16 is disposed becomes the guide portion 1f.
次に回転刃１１の使用態様について説明する（第３・４
図参照）。Next, the usage mode of the rotary blade 11 will be explained (3rd and 4th
(see figure).

工物Ｗに当接して回転刃１１の被加工物方向への移動が
規制される。したがって、被加工物Ｗ自体を削ることな
く、ばりＷｌのみを簡単に削ぎ落すことができる。First, the rotary blade 11 is connected to the rotor M via the connecting portion 14, and the motor M is driven to rotate the rotary blade 11. Then, the circumferential surface of the rotary blade main body portion 12 is brought into contact with the burr Wl of the workpiece W. Then, the burr Wl is cut by the blade part 13, and when the rotary blade 11 is further brought closer to the workpiece W, the burr Wl is cut by the blade part 13.
All of l will be cut. At this time, rotary blade 1
Even if the blade 1 is further pressed against the workpiece, the guide portion 1f comes into contact with the workpiece W, and the movement of the rotary blade 11 toward the workpiece is restricted. Therefore, only the burr Wl can be easily scraped off without cutting the workpiece W itself.
なお、第１実施例では、刃部１３に切欠部１３ａを設け
、ガイド部１フが刃部１３と面一となるように構成され
たものを示したが、刃部１３に切欠部１３ａを設けるこ

刃部１３より外側にガイド部１７を形成することもでき
る。In the first embodiment, the notch 13a is provided in the blade 13 and the guide part 1 is configured to be flush with the blade 13, but the blade 13 is provided with the notch 13a. The wire rod 16 is wound around the outer periphery of the blade portion 13 and arranged,
The guide portion 17 can also be formed outside the blade portion 13.
このように構成すると、回転刃１３と被加工物Ｗとの間
に線材１６の直径分の隙間が生じるため、例えば被加工
物Ｗ表面に植設される毛糸等の糸状部材を所定寸法に容
易にカットすることができる。With this configuration, a gap corresponding to the diameter of the wire rod 16 is created between the rotary blade 13 and the workpiece W, so that it is easy to make a filamentous member such as wool, which is planted on the surface of the workpiece W, to a predetermined size. can be cut into.
また、線材１６を巻き付ける間隔を被加工物Ｗの仕上げ
面取り幅とすれば、面取り加工も行なうことができる。Furthermore, if the interval at which the wire rod 16 is wound is set to the finished chamfering width of the workpiece W, chamfering can also be performed.

第３実施例のように、本体部３２周面に切欠凹部３５を
設けた回転刃３１とすることもできる。In the first embodiment, the rotary blade 11 was shown as having a structure consisting of a vertical blade part 13 and a guide part 17 formed by a wire 16 that is engaged with and held on the outer periphery of the blade part 13. As in the second embodiment shown, the rotary blade 22 has a circular through hole 25 formed in the cylindrical main body 22, and as in the third embodiment shown in FIGS. It is also possible to use a rotary blade 31 with a notch recess 35 provided on the circumferential surface.
第２実施例の回転刃２１では、貫通孔２５周縁が刃部２
３となり、貫通孔が設けられていない部位がガイド部２
フとなる。In the rotary blade 21 of the second embodiment, the peripheral edge of the through hole 25 is
3, and the part where the through hole is not provided is the guide part 2.
It becomes fu.
第３実施例の回転刃３１では、切欠凹部３５周縁が刃部

イド部３フとなる。In the rotary blade 31 of the third embodiment, the peripheral edge of the cutout recess 35 becomes the blade portion 33, and the portion where the cutout recess 35 is not provided becomes the guide portion 3f.
第２・３実施例の回転刃２１・３１は、刃部２３・３３
及びガイド部２７・３フが第１実施例と略同様に作用し
、被加工物を削ることなくばつの切削を容易に行なうこ
とができる。The rotary blades 21 and 31 of the second and third embodiments have blade portions 23 and 33.
The guide portions 27 and 3 function in substantially the same manner as in the first embodiment, making it possible to easily cut holes without cutting the workpiece.
なお、第２実施例の回転刃２１では、削られたばりＷｌ
