    • The invention concerns a boring tool comprising a main tool body and a tool holder which is adjustable relative thereto, as well as a counterweight coupled to the tool holder in such a way that upon a movement of the tool holder in one direction a movement of the counterweight occurs substantially in the opposite direction, wherein both the tool holder and also the counterweight are respectively arranged at least in part in a bore in the main tool body. To provide a boring tool of the above-mentioned kind which is suitable in particular for high rotary speeds, which is advantageous in terms of manufacture and which in addition provides a reliable precise balancing function, it is proposed in accordance with the invention that the main tool body has a clamping device, by means of which the main tool body can be elastically deformed so that both the tool holder and also the counterweight are respectively clamped in the bore.
    • 本发明涉及一种钻孔工具,其包括主工具主体和可相对于其调节的工具夹具,以及以这样一种方式联接到工具夹具的配重,使得在一个方向上使工具夹具移动时 配重基本上沿相反方向发生,其中工具夹具和配重都分别至少部分地布置在主工具主体中的孔中。 为了提供一种特别适用于高转速的上述类型的钻孔工具,其在制造方面是有利的,并且另外提供可靠的精确平衡功能,根据本发明提出了主要的 工具主体具有夹紧装置,通过该夹紧装置,主工具主体可以弹性变形,使得工具夹具和配重都分别夹在孔中。

    • The invention relates to a tool head, especially a fine drill head, comprising a machine shank and a tool shank having a joint center axis, wherein the tool shank has a rigid core and a head with a tool, supported by a parallel spring arrangement and is able to be elastically displaced in relation thereto, said head having several limbs which emanate therefrom and form the parallel spring arrangement, whereby at least one of said limbs is fixed to the core or machine shank. The inventive tool head also comprises a device for radial displacement of the head in relation to the core, comprising a positioning device which has a conical part and is guided inside the core. The conical part bears against a contact part of the parallel spring arrangement under pressure when in use. The core is configured with the parallel spring arrangement in a single piece.
    • 技术领域本发明涉及一种工具头,特别是细钻头,其包括机柄和具有接头中心轴线的工具柄,其中工具柄具有刚性芯和具有工具的头,由平行弹簧装置支撑, 能够相对于其弹性位移,所述头部具有从其发出的若干分支并形成平行弹簧装置,由此至少一个所述四肢固定在所述芯部或机械柄上。 本发明的工具头还包括用于头部相对于芯部径向移位的装置,包括具有锥形部分并被引导在芯部内部的定位装置。 当使用时,锥形部分在压力下抵靠平行弹簧装置的接触部分。 芯体采用平行弹簧装置构成一体。
