Abstract: A honing machine (100) for honing bores in workpieces has honing spindle (170) which is mounted movably in a spindle housing (130), is rotatable about a spindle axis (172) by means of a rotary drive (150), is drivable in an oscillating manner parallel to the spindle axis by means of a lifting drive and, at a tool-side end, has a device for fastening a honing tool arrangement with an expandable honing tool. Furthermore, an expanding drive for expanding the honing tool is provided, wherein the expanding drive is connected to the spindle housing and is coupled to a feed rod (180) running in the interior of the honing spindle. The honing machine is characterized by a monocoque housing (150), which has a spindle housing portion (150-1), which serves as the spindle housing, for receiving the rotary drive (135), and an expanding system portion (150-2), which is formed integrally with the spindle housing portion, for receiving the expanding drive (155).

Abstract: A honing machine (100) for honing a bore in a workpiece comprises a support structure (120) fixed to the machine, and at least one honing unit (130) which is mounted on the support structure. The honing unit has a main support (160) which can be mounted fixedly with respect to the support structure and a spindle unit (150) which is supported by the main support and in which a spindle shaft is rotatably mounted, wherein the spindle shaft is rotatable about a spindle axis by means of a rotary drive and, at a tool-side end (153), has a device for the fastening of a honing tool. Furthermore, a linear guide system which is arranged between the main support (160) and the spindle unit (150) for guiding a linear stroke movement of the spindle unit (150) relative to the main support (160) and a stroke drive for generating the stroke movement of the spindle unit (150) are provided.

Abstract: Various embodiments, methods and systems for implementing distributed data synchronization in a distributed computing system, are provided. In operation, a data record of a first data set is accessed. The data record is encoded to generate, for a first distributed invertible bloom filter (“DIBF”) data structure, a first DIBF record. The first DIBF record comprises a data field and a quantifier field that includes a quantifier value, which represents a reference count for the first DIBF record. The first and second DIBF data structures are accessed and decoded based at least in part on computing a difference between a quantifier value in the first DIBF data structure and a quantifier value in the second DIBF data structure. A determination whether a match exists between the first DIBF data structure and second DIBF data structure is made based on computing the difference between the first and second DIBF data structures.

Abstract: A honing machine comprises a machining unit for honing equipped with a tool spindle. It includes a machine base with an upper side and an upper machine part with an underside. The upper machine part has a vertical column, which has on its outer surface in an upper column region devices for receiving the machining unit that is equipped with a tool spindle. The machine further comprises an annular table with an underside, the annular table being arranged around the column in a lower column region and having a device carrier, which is rotatable about a vertical axis of rotation, for receiving at least one workpiece receiving device. The annular table and the upper machine part are respectively arranged with their underside on the upper side of the machine base and are mounted fixedly in place on the machine base.

Abstract: A cluster system includes a plurality of server computers and a data network. The cluster system is arranged to execute a plurality of virtual machines, wherein each of the virtual machines is allocated at least one virtual mass storage device. For each virtual machine, a first copy of the data of the associated virtual mass storage device is thereby stored on at least one local mass storage device of a first server computer and a second copy of the data of the associated virtual mass storage device is stored on at least one local mass storage device of a second server computer.

Abstract: A honing tool comprises a tubular tool body fastened with an end section in a tool shank and a cutting region on an opposite end section with at least one honing-stick accommodating opening. The dimensions of the honing-stick accommodating opening and of the honing stick are matched to one another so that the honing stick is accommodated in a radially movable manner, and essentially free of play in a circumferential direction of the tool body, between boundary surfaces of the honing-stick accommodating opening. A play-compensating device between the honing stick and the honing-stick accommodating opening comprises at least one elastically deformable supporting element which is supported with a pressure force, in a fitted state of the honing stick, on one hand on a side surface of the honing stick and on the other hand on a boundary surface, opposite the side surface, of the honing-stick accommodating opening.

Abstract: The invention relates to a method of coupling a honing tool (2) to a honing spindle (1), a honing spindle suitable therefor, a honing tool suitable therefor and a honing device comprising a honing spindle and a honing tool. According to the invention, a method of coupling a honing tool to a honing spindle is proposed which has the following steps: inserting the honing tool into the honing spindle into a joining position in which a honing-tool centre axis (24) is oriented coaxially to the honing-spindle centre axis (23); locking the honing tool on the honing spindle in the joining position by actuating an adjusting device (5, 6) assigned to the honing spindle. Furthermore, a honing spindle, a honing tool and a honing device which are suitable for carrying out the method are provided.
