Definitions

  • Such a dressing form does allow exact profiling of the grinding wheel, but is complex because a basic form must be produced for the different basic profile forms of the thread.
  • the invention has for its object to vary the profile of the grinding wheel compared to the thread profile in a simple manner with a universal dressing roller so that an optimal use of the grinding mandrel is possible.
  • the invention is based, to be able to retract the grinding spindle / mandrel with the grinding wheel as far as possible into the bore of the workpiece to be ground and the most favorable angle, but to dress the profile of the grinding wheel required in each case with a universal dressing roller. To achieve this object, the measures specified in the claim are proposed.
  • the grinding mandrel 1 with the grinding wheel 2 is guided through the workpiece at the grinding pitch angle ⁇ to the thread axis of the workpiece 3. As shown in FIG. 1, this is only possible up to a certain length because after a certain insertion length the grinding mandrel 2 no longer has any free play, it abuts the workpiece at 4. If the grinding pitch angle ß is reduced, longer threads or threads with a higher pitch can be ground, but the grinding wheel profile must be changed according to the grinding pitch angle ß in order to achieve the same thread profile.
  • Fig. 2 illustrates the relationships schematically.
  • the swivel device carries the grinding spindle with the grinding wheel as shown in FIG. 3.
  • the swivel device consists of the grinding spindle carrier 6, which is mounted in a circular path plane 7.
  • the radius R of the circular path level and its position corresponds to the distance to the center of the grinding wheel.
  • the grinding wheel can be guided past the dressing roller which remains in a horizontal position, the path being controlled by the computer program in such a way that the correct profile is generated.
  • This is shown schematically in FIG. 4.
  • the grinding arbor 1 with the grinding wheel 2 is guided past the universal diamond dressing roller by controlling the grinding slide in the x-Z direction in a way which corresponds to the corrected grinding wheel profile.
  • the starting position is shown and the end position of the grinding wheel after the dressing process is dash-dotted.
  • the dressing roller 10 keeps the location unchanged.
