APROACHES UPON THE INFLUENCE OF A NEW TAP DRILL GEOMETRY ON C45 STEEL PROCESSING

Adrian Sorin FAUR, Marcel Sabin POPA, Stefan SATTEL

Abstract


Abstract: The article presents an analysis of the current state of research on the influence of a tap drill geometry on C45 steel processing, that extends the tap drill's life by controlling the chip when the tap drill reverses. It relates to the improvement of a spiral tap drill, which discharges chips toward a shank via a helical flute. The article contains general details about C45 steel and its applications, the importance of high speed steel and tap drills geometry, factors that influence the geometry and threading problems. The research will be divided into 4 stages, which will be achieved with the support of Gühring Company and Technical University of Cluj-Napoca.
Key words: C45 steel; high speed steels; tap drill geometry; threading problems
