    • A spindle attachment device attached, for use, to a distal end of a spindle of a machine tool is provided. The spindle attachment device (11) includes a hollow casing (13) having an internal space; an input shaft (17) rotatably supported inside the casing; an output shaft (19) rotatably supported inside the casing; a coupling member (15) connected to the input shaft in order to join the input shaft to the spindle of the machine tool; a gear train (21) disposed between the input shaft and the output shaft in order to increase a rotation speed of the input shaft for a transmission to the output shaft; and a tap holder (25, 27) for mounting a tapping tool on the output shaft. The spindle attachment device increases the rotation speed of the spindle and transfers it to the tapping tool, and thus makes it possible to perform a tapping process on a workpiece at high speed, while maintaining the rotation speed of the spindle at a low level.
    • 提供了用于机床的主轴的远端附接的主轴附接装置。 主轴连接装置(11)包括具有内部空间的中空壳体(13) 可旋转地支撑在壳体内的输入轴(17) 可旋转地支撑在壳体内的输出轴(19) 连接到输入轴的联接构件(15),以将输入轴连接到机床的主轴; 设置在所述输入轴和所述输出轴之间的齿轮系(21),以便增加所述输入轴用于向所述输出轴的变速器的转速; 和用于将出钢工具安装在输出轴上的龙头保持架(25,27)。 主轴安装装置增加主轴的旋转速度并将其传送到攻丝工具,从而可以在将主轴的转速维持在低水平的同时高速地对工件进行攻丝加工。

    • A boring device includes a base on which a work is placed, a cutting tool inserted into the through hole of the work, a rotatingly driving device for rotating the cutting tool, and supporting jigs for supporting the cutting tool by bush surfaces. The cutting tool includes a tool body having a main flow path and second branch flow paths and cutting edges formed on the outer peripheral surface of the tool body. Recessed pockets are formed in the outer peripheral surface of the cutting tool at the respective portions opposed to the bush surfaces of the support jigs. A set screw is detachably fitted to each of the second branch flow paths. The set screw includes an orifice allowing the upstream side and the downstream side of each of the second branch flow paths to communicate with each other.
    • 钻孔装置包括放置工件的基座,插入工件的通孔中的切削工具,用于旋转切削工具的旋转驱动装置和用于通过衬套表面支撑切削工具的支撑夹具。 切削工具包括具有形成在工具主体的外周面上的主流路和第二分支流路以及切削刃的工具主体。 在与支撑夹具的衬套表面相对的各个部分处,在切削工具的外周表面上形成嵌入式凹穴。 固定螺钉可拆卸地装配到每个第二分支流动路径上。 固定螺钉包括允许每个第二分支流动路径的上游侧和下游侧彼此连通的孔口。
