  • the lathe chuck flange 30 according to fig. 2 is manufactured analogously to the spindle flange 10.
  • a reference spindle flange 70 is used and is shown in a longitudinal sectional view in fig. 12 and in a detail view in fig. 13.
  • reference is made at this point to the above statements, in particular to the statements regarding the manufacture of the spindle flange 10.
  • the process material 3, which is used to fix the positioning elements 12, 32 into the corresponding recesses 13, 33, should be as resistant as possible to all kinds of coolants and lubricants which are used in machine tools. On the other hand, it would also be conceivable, however, to seal the process material 3 in a suitable manner after curing. Furthermore, the process material has to be strong enough and withstand certain loadings, in particular transverse forces, impacts, etc. Preferably, the process material should have a lifetime of at least 10 years.

Abstract

L'invention concerne un élément de liaison (10; 30) pour constituer une interface (100) entre une pièce (2) d'une machine-outil et un composant (1) que l'on peut relier à celle-ci de façon réversible, par exemple une bride de mandrin de tour ou une bride de broche. Avec en tête l'objectif que le montage de l'élément de liaison (10; 30) sur un élément de liaison concourant (30; 10) puisse être facilement exécuté sans avoir à effectuer une fonction spéciale d'adaptation, il est proposé par la présente invention que l'élément de liaison (10; 30) comporte une face d'appui (11; 31) et au moins deux éléments de positionnement (12; 32) qui se logent chacun dans un évidement (13; 33) pratiqué dans la face d'appui (11; 31) de l'élément de liaison (10; 30), où ils sont reliés à l'élément de liaison (10; 30) d'une manière unissant les matières. L'invention concerne en outre un procédé de fabrication reproductible d'un tel élément de liaison.
