The wear status of a micro-endmill tool may be inferred by monitoring the chip production rate of the tool in operation. Chips may be extracted from a work area, captured on an adhesive surface, imaged, and counted to determine the chip production rate. When the rate of chip production falls, the feed rate of the micro-endmill may be modified to a level suitable for the current state of tool wear. In this manner, costly and inconvenient work stoppages to evaluate the wear status of a tool are eliminated.

A machine is provided, including at least one cutting tool in the form of cutting head with coolant supplied for machining parts from flat material, wherein the machine also includes a coolant containment and recovery system which includes: a waste removal apparatus, a coolant guard having at least one wall bounding a containment forming area, wherein the coolant guard is fluidly connected to the waste removal apparatus, wherein in use: the coolant guard is located upon a plate to be machined; and the containment forming area becomes a containment area, within which the cutting tool and coolant are both located during the machining process, so that used coolant can be removed.

A rotary part of a pump (200) is connected to a body member (110) to be rotatable together. When the body member is attached to a main shaft (20) of a machine tool (10), a rotation stopping pin (310) of a rotation stopping device (300) fits in a fitting hole (41) of the machine tool and abuts on a wall surface (41a) of the fitting hole, whereby the rotation stopping pin and a rotation stopping lever (340) axially move against an elastic force of a spring (320) and the rotation stopping lever disengages from an engagement hole (113) in the body member such that the body member becomes rotatable relative to a support part (150, 160) that rotatably holds the rotary part. A force detecting sensor (50) outputs a force detection signal indicating a force with which the rotation stopping pin is pressing against the wall surface.

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.

A residue remaining on an object to be cleaned after cleaning is easily detected and observed on the object. Adhesive materials for use in residue confirmation, which are applied in advance to an object to be cleaned for confirmation of a residue remaining on the object after cleaning, are formed by coloring chips produced during cutting work. The adhesive materials are preferably formed by coating and coloring the chips with paint, the paint emitting visible light in an excited state.

A cleaning method allows reliable cleaning of thread roots of a female screw. A cleaning method for a female screw includes producing a jet of a cleaning liquid from a nozzle in a direction tilted from an axis of the female screw without inserting the nozzle in the female screw, and directing the jet to impinge on a thread of the female screw while rotating the jet about the axis.

A sealing device for sealing a leakage flow on a machine element, which is circular in cross section, of a working machine includes a housing, which has an upstream end and a downstream end and through which the machine element extends, an upstream pressure chamber which is arranged at the upstream end of the housing, a downstream pressure chamber which is arranged at the downstream end of the housing, and a sealing element which is arranged between the upstream pressure chamber and the downstream pressure chamber. The sealing element is mounted within the housing and rests sealingly against the machine element. A bypass line runs around the sealing element and fluidly connects the upstream pressure chamber to the downstream pressure chamber. A throttle element designed to reduce the pressure of a flowing leakage fluid by a predetermined pressure difference is arranged in the bypass line.

In order to adapt a centrifugal cleaning installation (1) in a simple manner to different components (7), the centrifugal cleaning installation (1) is provided with a clamping unit (14) for clamping and retaining a component holder (4a, 4b, 5a-5d) for the component (7). The clamping unit (14) and a drive (6) are removably connected to the component holder (4a, 4b, 5a-5d) and said component holder (4a, 4b, 5a-5d) is adapted to a specific component (7) by positioning devices (25) and/or balance weights (26) provided on the holder.

Disclosed is a machining system wherein provisions are made to be able to remove machining chips reliably without requiring human intervention. The machining system includes: an image processing unit which detects the position and amount of machining chips by comparing images captured of a workpiece and a machining tool before and after execution of a machining step; a condition judging unit which, based on the detected amount of machining chips, determines whether or not there is a need to execute a removal step; and a result judging unit which judges the result of the removal step by comparing the images captured of the workpiece W and the machining tool before and after the execution of the removal step.
