Definitions
- the invention relates to a method for abrasive round machining of a workpiece and a device for carrying out the abrasive round machining process according to the Preambles of the independent claims.
- valve or nozzle needles typically one of the two faces is a sealing seat and the other the two surfaces forms a guide surface of the valve or nozzle needle.
- Valve or nozzle needles also for high pressure applications such as Fuel injection systems suitable for modern gasoline or diesel engines, where partial pressures be controlled from well over 1000 bar, are high requirements in terms to comply with the compliance of manufacturing tolerances.
- the transitional edge must between the seat and the guide surface sharp as possible and burr-free be educated.
- abrasive rounding can thus e.g. a cylindrical grinding process or a round honing process be. Accordingly, both a cylindrical grinding machine and a Rundhonmaschine as a device for carrying out an abrasive round machining process to watch.

- the grinder is with a Abrasive wheel and arranged with respect to the workpiece relative to the grinding wheel Provided deburring mandrel. If the grinding wheel is an abrasive surface of the As the workpiece grinds, a burr forms over the surface between the grinding surface and one adjacent edge formed in the region of the adjacent transition area Projecting surface.
- the deburring mandrel is arranged and formed such that the burr due to the rotation of the workpiece rotating about its axis from the deburring mandrel the grinding surface pressed back and ground on the next contact with the grinding wheel becomes.
- the object of the invention is to specify a method and a device for abrasive Round machining, which ensures reliable and precise machining of workpieces with a sharp and burr-free transition edge between two rotationally symmetric Allow surfaces in large-scale production.
- abrasive round machining process for machining a workpiece, which is a workpiece axis has performed an abrasive round machining process. While performing of the round machining process, the workpiece rotates about the workpiece axis, while simultaneously a first abrasive tool (in particular a grinding tool or a honing tool) rotating about a first tool axis and the workpiece be delivered against each other, in a first Abrasivvorgang (in particular a Grinding or honing process) to process a first workpiece surface.

- a first Measurement of the workpiece surface based on the measurement result, a first estimate of the determines the completion of the measurement-controlled abrasion process required time.
- This estimate is then used for a completion value the time required for the other abrasive process, the time difference between the estimate for completion of the gauged abrasive process and the time value for the completion of the other Abrasivvorgangs is determined. Is it? If the other abrasive process is a timed process, then the time value be determined due to the time already spent for this Abrasivvorgang. If, on the other hand, the other abrasive process is also a measurement-controlled one Process, the time value can be analogous to the estimated value for the first measuring process are estimated. Subsequently, that Abrasivvorgang, for which a shorter time has been determined until the completion of the operation, delayed according to the time difference. The determination of the time difference and the subsequent deceleration of one abrasive process can occur several times during the Implementation of the inventive method are made to the temporal To increase precision for the simultaneous termination of the two abrasive operations.
