  • Abrasive fabric sections serve as abrasives, which are then supported on the strip brushes lying behind in the direction of rotation. As a result, even uneven or profiled workpieces can be ground.

  • the present invention has the object to provide the structural requirements for a radia- les loading on a brush.
  • This radially directed insertion of the dovetail-shaped foot region of the brush into the likewise dovetail-shaped groove is made possible by the fact that the locking element engages in the narrow opening of the groove in the form of a profile rail or securing rail which extends from the front side of the groove Brush body is nachgeschoben.
  • This also has the advantage that the locking element can be made with a tight fit, so that reduce the radial length tolerances of the individual strip brushes to each other to a minimum. This leads to a correspondingly exact adaptation of the tool delivery to the contact plane with the workpiece. The thus given assurance of the assembly of the brush allows in addition to a much higher speed ranges of 1500 revolutions per minute and more.
  • an overgrip can be provided on the recesses, which engages the outwardly facing undersides of the locking element.

Abstract

L'invention concerne une brosse à polir présentant un corps de base métallique (11) doté de rainures (14) dirigées radialement vers l'extérieur dont l'ouverture (14a) est opposée au corps de base, dans lesquelles les zones de pied (16) de brosses à bandes (12) sont fixées par complémentarité de forme et/ou à force mais de manière interchangeable. Des sections de tissu de polissage (13) pouvant être fixées au corps de base (11) sont associées aux brosses à bandes (12). Par le fait qu'au moins un élément de verrouillage (18) fixant radialement au moins les brosses à bandes (12), et présentant un profil de section transversale pourvu d'une ouverture (18a) dirigée radialement vers l'intérieur en direction du corps de base, peut être fixé dans des évidements (19) du corps de base (11) et s'engage au moins en partie dans la rainure (14), la brosse à polie selon l'invention satisfait les exigences de construction pour une charge radiale.
