    Abstract: The present invention relates to a drilling tool and method for modifying a blind hole in a blade root insert of a wind turbine. The invention further relates to an apparatus and method for cleaning a blind hole. The method for modifying a blind hole comprises: removing a blade screw located in the blind hole, inserting a drilling tool into the blind hole, fixing the drilling tool in a drill, recessing the blind hole by a predetermined depth, with a maximum diameter of the end section and of the hole bottom after recessing being smaller than or equal to a diameter of the end section prior to recessing and a transition from the end section to the hole bottom being round after recessing, removing the drilling tool and the drill, mounting the blade screw in the modified blind hole.

    Abstract: There is provided a workpiece separation apparatus permitting input of a mixture of workpieces and chips stably within a flow current and separating them accurately and efficiently. The workpiece separation apparatus includes an input cylinder inserted within a separating container, and a fluid supplying means arranged so as to supply fluid to the separating container from a part lower than a lower end of the input cylinder, and configured such that the fluid overflows and flows out of the upper end of the separating container due to a flow current generated within the separating container, and such that the level of the fluid rises up in the input cylinder and the fluid does not flow out of the upper end of the input cylinder, but is maintained substantially in a resting state and at a level above the level of the upper end of the separating container.

    Abstract: A machine tool chip removal device including a coupling interface to couple with a rotatable spindle of a machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed. The chip removal device can also include a main fluid channel with an opening to receive pressurized fluid from the machine tool. The chip removal device can further include a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions. Each fluid delivery channel can be in fluid communication with the main fluid channel. In addition, the chip removal device can include one or more valves associated with the first and second fluid delivery channels to selectively allow fluid passage from the main fluid channel to the fluid delivery channels. The one or more valves can be actuated by varying fluid pressure and/or rotational speed.
