Definitions

  • Such a form of dressing as described there, enables 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 move 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.
  • the measures specified in claim 1 are proposed.
  • 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.

Claims (3)

  1. Méthode pour le meulage d'un filet de vis intérieur au moyen d'une meule pour moulurer (2) fixée à une broche de meulage (1), le meulage étant effectué à une inclinaison de meulage de la broche porte-meule étant inférieure à l'inclinaison du filet de vis à meuler et une correction du profilé étant exécutée lors du taillage de la meule (3),
    caractérisée en ce que
    (a) la broche de meulage (1) avec la meule (2) est montée sur un dispositif pivotant, le mécanisme de réglage duquel est commandable pour la modification de la position de l'axe de la broche porte-meule par l'intermédiaire d'un programme de calculation déterminant l'inclinaison optimale du filet de vis et le profilé respectif de la meule,
    (b) le façonnage du profilé de la meule étant effectué par un rouleau de taillage universel restant en position invariable sous une course de mouvement déterminée par le programme de calculation de la broche porte-meule aussi horizontale au-dedans des axes X et Z de la machine, et
    (c) que le meulage du filet de vis intérieur est exécuté après avec l'inclinaison corrigée et la meule étant profilée correspondemment.
  2. Méthode pour le meulage selon la revendication 1,
    caractérisée en ce qu'un porteur-broche (6) est logé est guidé dans un plan de trajectoire circulaire (7), le rayon (R) du plan de trajectoire circulaire (7) aussi bien que la position du plan de trajectoire circulaire correspondant à la distance du centre de meulage, le centre du plan de trajectoire circulaire coïncidant avec le centre de la meule.
  3. Méthode pour le meulage selon la revendication 1 et/ou 2,
    caractérisée en ce que le porteur-broche (6) est entrainé au moyen d'une broche filetée à billes (8) suspendue à la Cardan par l'intermédiaire d'un servomoteur (9).
