As a result, the auxiliary claw 1 is integrated with claw c of lathe chuck b, causing auxiliary claw 1 to wobble. There is no need to worry; the work piece a, which is larger than the standard of the lathe, can be clamped by the auxiliary claw 1 and turned on the lathe. This means that it can be fixed to chuck b.
【００１９】 また、旋盤チャックｂのツメｃに一体的に装着した補助ツメ１を取り外す場合 には、ボルト４を反対に回して弛め、ツメｃの突起部ｅの側面を押圧係止してい たボルト４の先端を係合受部２から後退させた後、補助ツメ１の係合受部２をツ メｃの突起部ｅから取り外すのみで簡単に、補助ツメ１をツメｃから取り外すこ とができる。[0019] Also, when removing the auxiliary claw 1 that is integrally attached to the claw c of the lathe chuck b. , turn bolt 4 in the opposite direction to loosen it, and press the side of protrusion e of claw c to lock it. After retracting the tip of the bolt 4 from the engagement receiving part 2, push the engagement receiving part 2 of the auxiliary claw 1 back. The auxiliary claw 1 can be easily removed from the claw c by simply removing it from the projection e of the claw c. I can do that.
