摘要： A method for honing a rotationally symmetric, non-cylindrical bore includes the steps of limiting the stroke of a honing tool between upper and lower reversal points, continoulsy detecting the actual diameter of the bore at all points along its length between the upper and lower reversal points, continuously comparing the actual diameter of the bore to a specified target diameters for at least one of the upper or lower reversal points, continuously limiting the stroke to regions of the bore in which the actual diameter is smaller than the target diameter, continuously limiting the stroke to regions of the bore in which the actual diameter is smaller than the target diameter, and reducing the stroke of the honing tool step-by-step based on the detected actual values of the diameter of the bore, so that it only the regions of the bore that are machined in which the actual diameter of the bore is smaller than the target diameter corresponding to the detected actual values of the diameter.

摘要： A honing machine for machining workpieces that have at least one bore to be machined by means of honing, comprises a plurality of workstations (180-1, 180-2), wherein at least one of the workstations is configured as a honing station (180-1, 180-2) that comprises at least one honing unit (150-1, 150-2) that has a spindle shaft (152) that is rotatable about a vertical spindle axis (155) by means of a rotary drive and is movable back and forth parallel to the spindle axis by means of a reciprocating drive. The honing machine has a pallet transport system (200) internal to the machine, for transporting workpieces from and to the workstations (180-1, 180-2) by means of pallets (210-1, 210-2). The pallet transport system (200) is designed such that different transport paths are freely configurable via a control unit (190) of the honing machine (200).

摘要： Provided are a machining method and a machining device that can reduce the displacement from a target round shape due to elastic deformation after machining, and can shorten the time required to machine a target round shape in the work. A machining method machines a round hole in a work, and includes: a hole-shape acquisition step of acquiring a shape of a hole of the work; an inverted-shape acquisition step of inverting the shape of the hole acquired at the hole-shape acquisition step relative to a target round shape to acquire an inverted shape; and an inverted-shape machining step of machining the hole in accordance with the inverted shape acquired at the inverted-shape acquisition step.

摘要： A honing machine for honing a bore in a workpiece comprises a support structure fixed to the machine and at least one honing unit which is mounted on the support structure and which has a spindle unit (150) in which a spindle shaft (152) is rotatably mounted, wherein the spindle shaft (152) is rotatable about a spindle axis (155) by means of a rotary drive (450) and, at a tool-side end (153), has a device for the fastening of an expandable honing tool. The honing machine furthermore comprises a stroke drive for generating a stroke movement of the spindle unit (150) and an expansion drive (550) for expanding the honing tool, wherein the expansion drive is coupled to an advancing rod (460) which runs in the interior of the spindle shaft. The spindle unit (150) has a spindle unit housing (310) which has a first housing portion (310-1) for accommodating the rotary drive (450) and a second housing portion (310-2) for accommodating the expansion drive (550). The rotary drive (450) is accommodated in an exchangeable first cartridge (400) and the expansion drive (550) is accommodated in a second cartridge (500) which is exchangeable independently of the first cartridge (400), wherein the first cartridge (400) is introducible into the first housing portion (310-1) and the second cartridge (500) is introducible into the second housing portion (310-2).

摘要： Processing tool for processing a surface of a workpiece. The processing tool includes a tool body which defines a tool axis. At least one first roll element, which is borne by the tool body, is rotatable around a first roll element axis and has a first outer surface with a rough surface structure in at least one first working section configured for rolling contact with the workpiece surface. Further, at least one second roll element, which is borne by the tool body, is rotatable about a second roll element axis and has a second outer surface that, in at least one second working section configured for a rolling contact with the workpiece surface, has a distance (r2) to the tool axis, which is less than a distance (r1) of the at least one first working section to the tool axis.

摘要： Methods of honing a surface are disclosed. The method may include spraying a coating having an initial average bulk porosity onto an engine bore wall and honing the coating to create an intermediate honed surface. The method may then include cleaning the intermediate honed surface and honing the intermediate honed surface with a cutting force of, for example, 110-130 kgf after the cleaning step. This may create a honed surface having an average porosity greater than the initial average bulk porosity. The methods may create a honed surface having a porosity that is more porous than the initially sprayed coating. The increased porosity of the honed surface may allow for increased oil retention in, for example, engine bores.
