Keeping the Customer First Tungaloy Report TE1008-E6 Innovative high performance cutting materials > PCBN (BX Series) and Ceramic (LX11) >

Nowadays, time consuming grindingprocesses are more and more replacedby hard turning operations. Various work piece profiles with smallest tolerances and different surface qualities can easily be machined without further grinding.Furthermore, dry machining is one posi-tive side effect leading to reduction in pro- duction costs. Tungaloy is a pioneer in the productionand development of PCBN and ceramiccutting materials. Already since the early 60ies and 70ies these high performance cutting grades have been produced in- house and successfully applied in variousmachining processes. Our...
