Definitions

  • the invention relates to a tool for finishing, brushing and / or polishing superfinishing surfaces of a workpiece, with a finishend, brushing and / or polishing acting active material having an at least partially curved active surface.
  • the invention further relates to a device with a tool, and to a method for producing a workpiece designed in particular as a ball screw spindle.
  • Finish tools for finish machining of workpiece surfaces are for example from DE 198 04 885 A1 as well as from the EP 1 506 839 B1 known. Finish tools are used to reduce the roughness of ground workpiece surfaces.
  • the layer thickness of the removed material is usually only a few microns.
  • finishing bricks and finishing stones with a curved effective surface are used.
  • brushing or polishing tools can also be used.
  • the present invention has the object to provide a tool with which high surface qualities can be produced in the shortest possible time.
  • the curved effective surface of the tool is annular and has radially inward.
  • the tool according to the invention is thus circumferentially closed, so that a ring is formed.
  • the radially inwardly facing surface is the effective surface with which a workpiece can be processed.
  • Characterized in that the active surface is annular the active surface may conform to a curved workpiece surface. The smaller the ratio between the diameter of the effective surface and the diameter of the workpiece to be machined, the better the effective surface of the finishing tool can conform to the surface of the workpiece.
  • geometric unevennesses for example, "chatter marks" produced during a grinding process
  • the superfinishing can be completed in one pass, so that time-consuming and expensive tool changes omitted. Since the active material is annular and can wear away radially outward, a large volume of wear is available. As a result, caused by wear tool change intervals are increased, downtime avoided and increases the efficiency.
  • the active surface is circular.
  • the rotational position of the tool and / or the workpiece at a given distance of the respective axes of rotation has no influence on the material removal process.
  • the profile of the active surface is mirror-symmetrical. In this way, the material removal process is independent of the direction in which the tool and the workpiece move along their axes of rotation relative to each other.
  • the profile of the active surface is arcuate, in particular, the active surface is convex radially inwardly formed.
  • This profile allows on the one hand a gentle engagement of the tool in a machined surface of the workpiece.
  • a ball running surface can be produced with such a radially inwardly convex shaped active surface.
  • Such a ball raceway can for example form a bearing surface of a ball bearing.
  • An example of such a workpiece is a ball screw, in particular the ball screw of a steering gear for motor vehicles.
  • the profile of the active surface can be exactly predetermined in the context of the work preparation, so that the tool can be used immediately and the profile of the effective surface does not have to first adapt to surfaces with pre-machined geometries.
  • the tool can be completely formed from the active material, so that it has a particularly simple structure.
  • the active material can also be arranged on an annular holding body. This facilitates the handling of the tool.
  • the active material and the holding body can be permanently connected to each other, so that a solid bond between the parts arises.
  • the active material and the holding body can also be releasably connected to each other, wherein means for fixing the active material are provided on the holding body. In this way, the active material can be exchanged after exceeding a wear limit and the holding body can be reused for new active material.

Accordingly, the invention also relates to a device with a tool described above. The device makes it easier to handle the tool. The further features of the device discussed below help to produce very complex geometries at high material removal rates.
  • the device can have a tool drive with which the tool can be driven to rotate about a tool axis. Although it can be significantly increased with a non-rotating driven tool, the material removal rate compared to tools known from the prior art, when rotating in a stationary tool, only the workpiece; However, by the rotating drive of the tool, a further increase in material removal performance can be effected.
  • the rotating drive of the tool also has the advantage that the active material along its annular active surface can wear evenly.
  • the tool can also be driven to oscillate about the tool axis. A superposition of rotational and oscillatory motion is possible.
