    • A milling tool includes a milling body and a plurality of insert-carrying cartridges mounted in the milling body. Each cartridge includes front and rear side surfaces which oppose leading and trailing walls of a pocket formed in the milling body. The cartridge also includes inner and outer flank surfaces which interconnect the front and rear side surfaces. The body includes a slot which opens into the front side surface at a location intermediate the ends of the cartridge, to divide the body into a rigid base portion and an expandable portion. The base portion has a seat for a cutting insert. A threaded hole is formed in the slot intermediate the slot ends to receive a threaded wedge screw. Tightening of the screw causes the expandable portion to be expanded into contact with the leading wall of the pocket and thereby push the base portion into tight contact with the trailing wall of the pocket. Accordingly, the cartridge is secured within the pocket by a tight frictional contact which resists chatter. The cartridge carries an adjusting screw to enable the cartridge to be adjusted in a direction along the axis of rotation of the milling body.
    • 铣削刀具包括铣削主体和安装在铣削主体中的多个插入件。 每个墨盒包括与形成在铣削体中的凹穴的前壁和后壁相对的前后表面。 该盒还包括互连前表面和后侧表面的内表面和外侧面。 主体包括一个槽,该槽在中间位于盒的端部的位置处向前侧表面开口,以将主体分成刚性基部和可扩张部分。 基部具有用于切削刀片的座。 螺纹孔形成在槽端部中间的狭槽中,以容纳螺纹楔形螺钉。 螺钉的拧紧导致可膨胀部分膨胀成与袋的前导壁接触,从而推动基部与袋的后壁紧密接触。 因此,通过紧密的摩擦接触将卡盒固定在口袋内,抵抗喋喋不休。 墨盒带有调节螺钉,以使墨盒能够沿着研磨体的旋转轴线的方向调节。

    • A drill is provided having a generally cylindrically shaped body. The body has a rear end structured to releasably connect with a torque transmitting machine in a conventional manner. The body has a forward end which is provided with diametrically opposed seats. Each seat releasably retains a cutting insert. Each cutting insert has a cutting edge projecting forwardly from the forward end of the body. Further, the cutting inserts are oriented so that one cutting edge is at a ten degree positive lead angle and the other cutting edge is at a five degree negative lead angle, the angles being measured normal to the center line of the drill. In operation, the drill is used to provide a bore hole in a workpiece, the bore hole having a predetermined perimeter. As the rotating drill contacts the workpiece, the cutting edges contact the workpiece in a predetermined, progressive manner which thereby creates a plurality of spaced apart circular notches of differing depth in the workpiece. The result is controlled, easily managed removal of chips of the material cut from the workpiece.
    • 提供具有大致圆柱形的主体的钻头。 主体具有构造成以常规方式与扭矩传递机器可释放地连接的后端。 主体具有向前端部,其具有直径相对的座椅。 每个座可释放地保持切削刀片。 每个切削刀片具有从主体的前端向前突出的切削刃。 此外,切削刀片被定向成使得一个切削刃处于十度正的引导角,另一个切削刃处于五度负的引导角,该角度被测量为垂直于钻头的中心线。 在操作中,钻头用于在工件中提供钻孔,钻孔具有预定的周长。 当旋转钻接触工件时,切削刃以预定的渐进方式接触工件,由此在工件中产生不同深度的多个间隔开的圆形凹口。 结果是控制,容易地管理从工件切割的材料的切屑。
