Abstract

L'INVENTION CONCERNE L'USINAGE DES PIECES ALLONGEES. ELLE SE RAPPORTE A UN PROCEDE SELON LEQUEL UNE PIECE W EST PORTEE SUR UNE PARTIE AU MOINS DE SA LONGUEUR PAR UN SUPPORT 12, PAR EXEMPLE UN MANDRIN MAGNETIQUE, LA PIECE POUVANT TOURNER PAR RAPPORT AU SUPPORT. UNE FORCE MAGNETIQUE EST APPLIQUEE A LA PIECE AFIN QU'ELLE SOIT MAINTENUE PAR LE SUPPORT LORSQU'ELLE TOURNE AUTOUR DE SON AXE, ET UN OUTIL 16 D'USINAGE, PAR EXEMPLE LA MEULE D'UNE RECTIFIEUSE, ASSURE L'USINAGE DE LA PIECE LORSQU'ELLE TOURNE PAR RAPPORT A SON SUPPORT 12. APPLICATION A L'USINAGE DES TREPANS ALESEURS ET DES MECHES EN SPIRALE.THE INVENTION CONCERNS THE MACHINING OF ELONGATED PARTS. IT RELATES TO A PROCESS ACCORDING TO WHICH A PART W IS CARRIED ON A PART AT LEAST OF ITS LENGTH BY A SUPPORT 12, FOR EXAMPLE A MAGNETIC CHUCK, THE PART CAN TURN RELATIVE TO THE SUPPORT. A MAGNETIC FORCE IS APPLIED TO THE PART SO THAT IT IS HELD BY THE SUPPORT WHEN IT TURNS AROUND ITS AXIS, AND A MACHINING TOOL 16, FOR EXAMPLE THE WHEEL OF A GRINDING MACHINE, ENSURES THE MACHINING OF THE PART WHEN IT TURNS IN RELATION TO ITS SUPPORT 12. APPLICATION TO THE MACHINING OF BORING TREPANS AND SPIRAL BITS.
