High performance machine taps HSSE Using of machine taps of general purpose made of the molybdenum steel class HSS, provides good results of work with conventional machines with the standard cutting speed and it is technically and economically justified in many cases of unitary or short and medium serial cutting. There are cases, where using the tool of the higher purchase price results in a significant lowering of producing costs, because of significant increase of cutting speed, tool durability as well as decrease of labour consumption and cost of servicing the work stand. Such possibilities are given by using the high performance machine taps. Basic features of high performance machine taps Blade material High speed steel HSSE, high speed powder steel HSSE-PM and solid carbide VHM characterised with thermal and abrasion resistance Heat treatment High hardness with preserving good ductility Surface treatment Using the super hard coatings made of titanium nitride TiN, titanium carbonitride TiCN, titanium-aluminium nitride TiAlN or aluminium-chromium nitide AlCrN and passivation OX Working part geometry Adopting to each material group with various workability Super hard coatings properties Symbol cerlikon balzers coating Name Color Hardness HV 0,05 Max temp. usage Usage TiN BALINIT A Titanium nitride Gold 2300 600 Universal TiCN BALINIT B Titanium carbonitride Blue grey 3000 400 Difficult workable, hard grinding materials TiAlN BALINIT FUTURA NANO Titanium- aluminium nitride Grey violet 3300 900 As the above ones dry machining HL BALINIT HARDLUBE о < + о Ti W Dark grey 3000 800 Difficult workable, hard grinding materials TECHNICAL INFORMATION 3.5.
