Abstract
L'INVENTION CONCERNE DES ALESOIRS ETAGES A PAS FORTEMENT IRREGULIERS DES TRANCHANTS. UN ALESOIR PRESENTE UN ETAGE DE FORAGE 13 ET UN ETAGE D'ALESAGE PLUS GRAND 14 PRESENTANT, LE PREMIER UN ANGLE D'ATTAQUE 16, ET, LE SECOND UN ANGLE D'ATTAQUE 17. LE PAS ENTRE LES DENTS 7, 8... EST IRREGULIER ET LES RAINURES BRISE-COPEAUX INTERCALEES ENTRE DEUX DENTS DE PLUS GRAND PAS SONT PLUS PROFONDES QUE LES AUTRES. L'INVENTION S'APPLIQUE AU FORAGE ET A L'ALESAGE COMBINES AVEC UN SEUL OUTIL.THE INVENTION CONCERNS STEP RIMS WITH NOT STRONGLY IRREGULAR EDGES. A REAMER HAS A DRILLING STAGE 13 AND A LARGER BALE STAGE 14 HAVING, THE FIRST AN ANGLE OF ATTACK 16, AND THE SECOND A ANGLE OF ATTACK 17. THE STEP BETWEEN TEETH 7, 8 ... IS IRREGULAR AND THE CHIPBREAKER GROOVES INTERPRETED BETWEEN TWO TEETH WITH LARGER PITCHES ARE DEEP THAN THE OTHERS. THE INVENTION APPLIES TO DRILLING AND BORING COMBINED WITH A SINGLE TOOL.
