Definitions

  • the invention relates to a method and a device for grinding cams or the like. With the features specified in the preamble of claim 1 and claim 3, respectively.
  • the pre-grinding wheel is designed as an interchangeable grinding wheel that can be removed from the grinding spindle.
  • This interchangeable grinding wheel is provided with profiles to break the edges of the cams during pre-grinding.
  • the pre-grinding wheel is not moved laterally, but the cam contour is pre-ground by a single insert grinding and then the interchangeable grinding wheel decreased.
  • a different pre-grinding wheel is required for each cam width or chamfer shape.
  • the invention is therefore based on the object of avoiding these disadvantages and of specifying a grinding method or a grinding device, in particular a targeted cooling of the grinding zone being possible during the pre-grinding.
  • the formation of the pre-grinding wheel with at least one radially circumferential groove on the outer circumference ensures that the entire circumferential surface of the cam is not machined at once. This entails a reduction in heating, which also contributes to the fact that a coolant can be introduced to the webs remaining in the grooves during grinding. High cutting speeds and an increased machining volume per unit of time are therefore possible, i.e. The feed rate and depth of cut can be increased so that changes in structure or grinding cracks in the workpiece can be ruled out even with high-speed machining. This enables faster and therefore more economical grinding.
  • a further advantageous embodiment of the method according to claim 1 is the subject of claim 2. Further embodiments of the device according to claim 3 are the subject of claims 4 to 7.
  • the pre-grinding wheel 1 is wider than the cam 3 and has two radial annular grooves 4 on the outer circumference. These grooves 4 become wider towards the inside, so that between the flanks of the grooves 4 and the webs 7 which remain during grinding, there are clearance angles into which coolant is supplied. The actual grinding area does not go over the entire cam width. This can be seen in particular from FIG. 4, where it is shown that a galvanically applied grinding layer 9 is interrupted by the grooves 4.
  • This grinding wheel can also be designed with a metal-bonded CBN grinding surface.
  • FIG. 7 Another possibility of executing the pre-grinding wheel is shown in FIG. 7.
  • the abrasive coating protrudes somewhat beyond the groove side surface, so that the grooves 4 that run radially on the outer circumference can be made with the same width down to the groove base.
  • the chamfer 8 on the left of the cam 3 in the picture is simultaneously ground.
  • the pre-grinding wheel 1 has projecting edges 5 and 6, which are freely triangular in cross section according to FIG. 2 or 3 and are approximately triangular in cross section and whose inclination corresponds to the desired profiling of the chamfers 8.
  • the pre-grinding can be completed after a single axial displacement of the pre-grinding wheel 1. However, other grinding cycles can also be connected if required. In any case, the movement of the pre-grinding wheel is repeated until the finished pre-grinding dimension is reached. Each grinding process takes place with one full or several workpiece revolutions.
  • the cam 3 is finished by the finish grinding wheel 2. This is shown in Fig. 1.
  • the outer circumference of the finished grinding wheel 2 has the finished profile shape of the cam 3.
  • the finish grinding wheel 2 has a cylindrical outer circumference. But it is easily possible that the finish grinding wheel 2 is also used for grinding oblique or spherical cams; it then only has to have an appropriate profile shape.
  • the finish grinding wheel can have a different grain and bond than the pre-grinding wheel in order to obtain the desired surface and to influence the grinding parameters in a targeted manner.
  • the finishing grinding wheel can have a very simple profile shape. Furthermore, no lateral forces on the finish grinding wheel or the workpiece occur during finish grinding, which can negatively influence the working accuracy, ie the grinding wheel or the camshaft are only loaded radially.
  • Fig. 5 it is shown that a cam 3 is finish-ground while the adjacent cam still has the raw cast surface.
  • the pre-grinding wheel 1 is about to be used for the first time. The result of this use corresponds to the situation shown in FIG. 2.
  • both grinding wheels 1 and 2 are mounted on a common spindle. This enables the cam 3 to be pre-ground and finished in one setting.
  • the cams are arranged very close to one another, it is not possible to work with grinding wheels 1 and 2 mounted on a spindle. In such a case, the grinding wheels 1 and 2 are arranged opposite one another on the camshaft; see Fig. 6. Two grinding spindles must be provided here.
