Definitions

  • the invention relates to a method for finish machining peripheral surfaces of rotationally symmetrical workpiece sections and to a device suitable for carrying out the method.
  • Finishing which is also referred to as superfinishing, is a machining process with indefinite cutting edges.
  • workpieces such as crankshafts, camshafts, transmission shafts or other components for power and working machines can be edited to produce a desired surface fine structure.
  • a finishing tool with granular cutting agent is pressed against the peripheral surface to be machined.
  • the workpiece is rotated about its workpiece axis. At the same time, a relative movement that oscillates parallel to the workpiece surface is produced between the workpiece and the finish tool resting against the peripheral surface.
  • the workpiece section to be machined may be, for example, a main bearing or a crank bearing of a crankshaft or a camshaft bearing.
  • finishing is a thermally neutral processing method in which no soft skin interspersed with microcracks or surface tensions arises. Finishing is often used after a grinding process as the last machining process of a process chain to remove the soft skin, re-exposing the original microstructure, increasing the support of the roughened surface structure, and improving the component geometry in terms of roundness and shortwave errors in the axial and circumferential directions.
  • Grinding is the last shaping machining operation.
  • the geometry of the grinding tool of the machine control is known, so that the workpiece can be contoured by grinding according to the guided by the machine control tool guide.
  • a prerequisite for this shaping is the regular dressing or calibration of the grinding tools.
  • the grinding process is usually unable to achieve the achievable by the finish machining surface properties.
  • the preservation of the axial contour is usually in the foreground.
  • An improvement in the form values on cylindrical bearings takes place mainly in the radial direction and is highly dependent on the pre-processing.
  • short-wave error components e.g. with more than 15 waves on the circumference
  • long-wave components such as e.g. Ovals, triangles or quadrilaterals can not be positively influenced by finishing.
  • the cutting volume through the finishing process is usually less than 10 ⁇ m.
  • the material removal of the finishing process is normally adjusted to the pre-processing.
  • Grinding is usually the last shaping machining operation. This means that the contouring of a rotationally symmetrical bearing point essentially takes place through the grinding process preceding the finishing process.
  • a continuous dressing of the grinding wheel is imperative for the shaping and design of the bearing. Depending on the requirement and the drawing tolerance of the bearing, the dressing cycle is reduced or extended. However, the grinding process is usually unable to achieve the achievable by the finish machining surface properties.
  • a crowned (barrel-shaped, convex) shape of rotationally symmetric bearing sections can help to reduce bearing damage due to flight and form errors of the components interacting in the bearing.
  • specified by the customer final generatrix requirements regarding crowning are usually expressed in diameter differences of a few micrometers between different axial positions of the bearing section.
  • a crowned macro-shape can be achieved by appropriate dressing of the circumferential surfaces of the grinding wheels used during grinding (cf. EP 1 181 132 B1 . Fig. 5 ).
  • the EP 1 514 642 A2 describes a device for finish machining of shafts, in particular crankshafts and camshafts, with a tool carrier and an endless abrasive belt, which has a flexible carrier and an abrasive layer with hard material.
  • the device is used for processing a rotating about its axis of rotation workpiece.
  • a sanding belt drive continuously drives the sanding belt during workpiece machining.
  • the tool carrier has a machining head with two mutually spaced band deflections, which limit a working range of the machining head, wherein the grinding belt is guided over the tape deflections and passes in the work area on the peripheral surface of the workpiece to be machined.
  • the circulating abrasive belt outside of the work area is associated with a device for dressing the abrasive layer, which has a deliverable during the workpiece processing against the abrasive layer of the belt at a speed adjusted to the workpiece processing belt speed adjustable dressing tool.
  • the dressing tool has a convex contour transverse to the direction of tape travel, which is transferred to the abrasive layer during dressing. As a result, a slightly convex contour can be generated on the machined workpiece section.
  • the DE 10 2011 087 252 B3 which forms the basis for the preamble of claim 3, describes an apparatus for finishing machining a particular annular workpiece, comprising a carrier for connection to a finishing tool holder for holding a finishing tool and drive means for generating a linear oscillating movement of the carrier ,
  • An oscillation unit is provided which has a finish tool holder for receiving a finish tool and an auxiliary drive means for generating a linear oscillation movement of the finish tool holder.
