    Abstract: The invention describes an apparatus (1) for a cutting edge preparation of cutting tools (5), in particular of drills or milling tools or similar tools (5), in particular of hard-metal cutting tools, wherein during a relative movement the cutting tool (5) interacts in a machining fashion with a flexibly-bonded grinding body (2) that is provided with abrasive particles, the particles of the grinding body (2) influencing the edge geometry of the cutting tool (5),
    wherein the grinding body (2) is adapted with its dimensions substantially to the dimensions of the respective cutting tool (5) that is to be prepared and is accommodated in an exchangeable holder (4) which is arranged in a region of a processing device, in particular of a tool grinding machine, and is held such that it is machinable by the cutting tool (5) for the cutting edge preparation. Furthermore, a corresponding method and a corresponding grinding body (2) are given.

    Abstract: The device is for cleaning the inner surface of a pipe. The device has a spindle arranged to be rotated and having a front end and a rear end between which a plurality of elastic metal blades are attached both in the rotation direction of the spindle and in the direction perpendicular to the rotation direction to clean the inner surface of the pipe. The blades has a shape that is curved at at least two points such that they curve at least once towards the circumferential direction of the spindle and at least once outwards from the circumferential direction of the spindle to prevent the device from getting stuck in uneven pipe systems.

    Abstract: A gear grinding unit, capable of grinding a tooth flank of a gear to have fine surface roughness without requiring any special shaping work such as dressing, includes a threaded grinding part which is rotatable around a rotation axis (S1) and engages with a tooth of a gear to be ground. Through a rotational motion of the threaded grinding part, a tooth flank of the gear is ground. The threaded grinding part includes a plurality of flexible abrasive sheets each including a virtual circle having a diameter that equals a root diameter (DA) of the threaded grinding part and a bulge part bulging radially outward from the virtual circle. With the bulge parts of the abrasive sheets mutually shifted around the rotation axis (S1), the abrasive sheets are overlapped along the rotation axis (S1) to form the threaded grinding part.
