    • Machining tool comprising a main tool body, a slider element received at least partially in an opening in the main tool body and movable relative thereto in an adjustment direction between a first and second position, and a drive shaft having two threaded portions, wherein the first threaded portion of the drive shaft cooperates with the threaded portion of the slider element and the second threaded portion of the drive shaft cooperates with the threaded portion of the main body so that upon rotation of the drive shaft about its axis the slider element moves relative to the main body between the first and second positions. Ultrafine adjustment of the slider element is possible in almost zero-backlash fashion in relation to the main tool body in both adjustment directions by providing a spring element engaging the slider element and biased in the direction of one of the two positions.
    • 加工工具包括主工具主体,至少部分地容纳在主工具主体的开口中并且可在第一和第二位置之间沿调节方向相对于其移动的滑块元件和具有两个螺纹部分的驱动轴,其中第一 驱动轴的螺纹部分与滑块元件的螺纹部分配合,并且驱动轴的第二螺纹部分与主体的螺纹部分配合,使得当驱动轴绕其轴线旋转时,滑块元件相对于 主体在第一和第二位置之间。 通过提供接合滑块元件并沿两个位置中的一个位置的方向偏置的弹簧元件,两个调节方向相对于主工具主体以几乎零的间隙方式进行超微调节。

    • The present invention concerns a milling or boring tool comprising a main tool body rotatable about a tool axis and a cutting element which can be fastened to the main tool body and which has a cutting portion or a cutting insert seat for receiving a cutting insert. To provide a fastening system for fastening the cutting element to the main tool body, which is to be easily implemented at low cost, which allows highly accurate positioning of the cutting element on the main tool body and which in addition permits very rapid exchange of the cutting element, it is proposed according to the invention that a centering pin which is arranged parallel to the boring axis and the axis of which does not coincide with the tool axis is connected on one part, the main tool body or the cutting element, and a corresponding centering opening is provided on the other part, the cutting element or the main tool body.
    • 本发明涉及一种铣削或钻孔工具,其包括可围绕刀具轴线旋转的主工具主体和可紧固到主工具主体上并具有用于接收切削刀片的切削部分或切削刀片座的切削元件。 为了提供用于将切割元件紧固到主工具主体的紧固系统,其将以低成本容易地实现,这允许将切割元件高度精确地定位在主工具主体上,并且还允许非常快速地更换 切割元件,根据本发明,提出了平行于钻头轴线并且其轴线不与工具轴线重合的定心销连接在主工具主体或切割元件的一部分上,以及 在另一部分,切割元件或主工具主体上设置相应的对中开口。
