  • the machine component to be ground according to the invention has at its one end a bearing journal, which in comparison to the other areas of the machine component has a reduced diameter. Also, this journal must be centered with high precision and then be ground around its outer circumference. In addition, there is the grinding of the outer areas and the inner recess. In this case, can no longer be ground with the known methods, because with the usual methods for clamping certain areas of the machine component are no longer accessible Especially when the machine component in question here is a gear shaft, there are very high demands on the accuracy in terms of dimensional accuracy and centering Even the smallest changes, such as those that could result from inaccuracies in the grinding, in some cases lead to extremely adverse effects
  • the peripheral areas, but also end faces and tapered transition surfaces on the outer contour of the machine component can be ground.

Abstract

L'invention concerne un procédé de rectification d'un composant de machine, faisant par exemple office d'arbre de transmission, lequel composant tourne autour de son axe longitudinal lors de la rectification et présente un tourillon à son extrémité axiale ainsi qu'un évidement à son extrémité opposée. La rectification est effectuée dans une seule et même rectifieuse. Au cours de la rectification, le composant de machine passe par différents états de serrage causés par un mandrin d'une poupée porte-pièce (4) à mors amovibles (6) et à pointe de centrage, par une lunette (11) et/ou un fourreau de contre-pointe (8). L'avantage des états de serrage variables réside dans le fait que le composant de machine reste, en position de serrage, au même endroit d'une rectifieuse unique, dans tous les différents états de serrage. Ainsi, des exactitudes de dimension, de forme et de position améliorées peuvent être obtenues de façon économique et toutes les zones à rectifier du composant de machine sont successivement accessibles aux meules.
