Original abstract

An effective threading of austenitic steel with HSS taps protected by CrAlN, TiCN and TiN PVD coatings was tested. The chrom-nickel austenitic non-stabilized steel (X5CrNi 18-10), was threaded with the HSS-E M6-6H Narex Zdanice taps at the cutting speed vc=10 m/min, with outer cooling fluid Cimperial HD 801-03 – 10%, a flood cooling intensity and 60 bars in press. A CNC machining centre MCV 1210 with a built-in dynamometer KISTLER 9272 were used for the machining technology and measurements. The results showed an effective cutting with a tool life of 40-45 holes and acceptable quality of threads for HSSE with the CrAlN coating.

Tento článek popisuje efektivní řezání austenitické oceli pomocí závitníků HSS-E M6-6H Narex Zdanice, chráněných CrAlN, TiCN and TiN PVD povlaky. Jako obráběný materiálbyla použita chrom-ncklová nestabilizovaná ocel X5CrNi 18-10. Řezná rychlost vc=10 m/min, vnější chlazení s Cimperial HD 801-03 – 10%, 60 barů. CNC centrum MCV 1210 s dynamometrem KISTLER 9272. Výsledky prokázaly obrobení 40-45 s přijatelnou kvalitou opracování, nejlepších výsledků bylo dosaženo s CrAlN povlakem.
