Tool layout for making boreholes in materials such as fiber composite materials
摘要：
The invention pertains to a tool layout (10) for making boreholes (12) in materials (14) such as fiber composite materials, comprising a cutting tool (16) with a drill shaft (20) having a suction channel (18) and with a drill head (26) having at least one tool blade (22, 24), wherein the drill head (26) has a larger diameter DBK than the drill shaft (20) in order to form an intermediate space (28) between drill shaft (20) and the wall of the borehole, and a suction device (30) coupled to the suction channel (18) of the drill shaft (20) to suction away the shavings removed through at least one suction opening (32, 33) of the drill head (26) coordinated with the at least one cutting blade (22, 24) into the suction channel (18). To improve the suctioning of the shavings and/or the cooling of the tool and work piece, an outer wall (64) of the drill head (26) has at least one recess (64, 66) extending for the entire length of the drill head (26) and emerging into the at least one suction opening (32, 33) as a crossover channel by which a connection is produced between the intermediate space (28) bounding the drill shaft and the suction opening (32, 33).
摘要（中）：

本发明涉及用于在诸如纤维复合材料的材料（14）中制造钻孔（12）的工具布局（10），其包括具有钻杆轴（20）的切割工具（16），所述钻杆轴具有吸入通道（18） 具有至少一个工具刀片（22,24）的钻头（26），其中所述钻头（26）具有比所述钻杆轴（20）更大的直径DBK，以在所述钻头轴（22,24）之间形成中间空间 （20）和钻孔壁，以及联接到钻杆轴（20）的抽吸通道（18）的抽吸装置（30），以通过至少一个吸入开口（32,33）吸出通过 所述钻头（26）与所述至少一个切割刀片（22,24）配合到所述抽吸通道（18）中。 为了改善刨花的抽吸和/或工具和工件的冷却，钻头（26）的外壁（64）具有至少一个凹槽（64,66），该凹槽在钻头的整个长度上延伸 头部（26）并且作为交叉通道出现在至少一个吸入开口（32,33）中，通过该交叉通道在限定钻杆轴和吸入口（32,33）之间的中间空间（28）之间产生连接。
