    • A chuck includes a holder body, a clamp sleeve, and a large number of needle rollers. The holder body has a shank portion, a flange formed at one end of the shank portion, and a chuck sleeve that extends from the flange in the direction away from the shank portion. The clamp sleeve is fitted onto the outer circumference of the chuck sleeve such that the clamp sleeve is rotatable and axially movable relative to the chuck sleeve. The needle rollers are disposed between the chuck sleeve and the clamp sleeve over the entire circumference. The clamp sleeve is rotated to cause the needle rollers to revolve spirally along the outer circumferential surface of the chuck sleeve while rotating about their own axes in order to decrease and restore the diameter of the chuck sleeve. In the chuck, a groove having a predetermined depth is formed in the end surface of the flange opposite the shank portion such that the groove surrounds the base end of the chuck sleeve through which the chuck sleeve is joined with the flange.
    • 卡盘包括夹持器本体,夹紧套筒和大量滚针。 保持器主体具有柄部,在柄部的一端形成的凸缘以及从凸缘向离开柄部的方向延伸的卡盘套筒。 夹紧套筒装配在卡盘套筒的外周上,使得夹紧套筒可相对于卡盘套筒旋转和轴向移动。 滚针在整个圆周上设置在卡盘套筒和夹紧套筒之间。 旋转夹紧套筒以使滚针沿着卡盘套筒的外周表面螺旋地旋转,同时围绕它们自己的轴线旋转,以便减小和恢复卡盘套筒的直径。 在卡盘中,在与轴部相对的凸缘的端面中形成具有预定深度的凹槽,使得凹槽围绕卡盘套筒的基部端部,卡盘套筒通过该基部端部与凸缘接合。

    • PURPOSE: Disclosed is an inexpensive end mill integrally formed with a shank capable of jointing a shank of the main body of the end mill to a tapered bore of a holder with heating lower than a shrinkage fitting temperature. CONSTITUTION: An end mill holder in which a tapered face gently tapering backward is open to a front end of a holder is provided in front of the holder, a cutting method is provided in a front part of a main body, a shank in which an outer circumference of the shank is gently tapering backward is provided in a back side of the main body, and an end mill in which a back end face in the front part of the main body is perpendicularly projected to the outer circumference of a front end of the shank is provided. With a heat lower than a shrinkage fitting temperature, the shank of the main body is forcibly fitted into a tapered bore in the holder to bring the back end face of the main body into contact with the front end of the holder and bond the main body of the end mill to the holder.

    • PURPOSE: A collet chuck for a winder is provided to prevent a condenser from slipping as the side wall of the condenser is inclined, and engaged with the condenser. CONSTITUTION: A collet chuck(1) for a winder comprises a shank(10), a tapered portion(20), a receiving unit(30), slits, a side wall(33), first and second fixing pieces(32a,32b). A coupling unit(11) formed at the rear part of the shank is connected to a spindle shaft. The tapered portion is formed in the leading end of the shank, and the diameter of the tapered portion is gradually reduced toward the back. A condenser is inserted into the inlet of the receiving unit. The slits are connected from the receiving part, and formed toward the rear part of the receiving unit. The side wall is formed in the receiving unit. The first and second fixing pieces are formed into square shapes as the condenser.
