FOR HARDTURNING OF:
Case and induction hardened steels Tool and die steels Bearing steels and many cast irons WHAT IS POLYCRYSTALLINE CUBIC BORON NITRIDE? Diamond, cubic carbon, is the hardest, most abrasive-resistant material known to man. It is therefore an ideal tool material. In the presence of extreme heat and a catalyst, (iron, nickel or cobalt), diamond transforms to the hexagonal carbon form, graphite. This is why ferrous materials are not generally machined with diamond.

The second hardest material, Cubic Boron Nitride (CBN), is created by man, using temperatures and pressures similar to those used for diamond synthesis, and does not have this inherent weakness when it comes to the machining of ferrous materials.
While CBN will machine soft irons and steels with ease, the relatively high cost of CBN tools makes them less cost-effective than conventional tool materials which will also perform well on soft materials. Used in the correct manner, however, CBN can offer cost-effective rapid stock removal and finishing of hardened steels and certain softer ferrous materials. Technodiamant offers two types of CBN material: 1. TDA-H- has a high CBN content and is designed for heavy machining applications, where high stock removal rates provide an attractive alternative to conventional techniques. 2. TDA-M- has a reduced CBN content and is designed for finishing and semi-finishing applications where grinding with conventional abrasives proves difficult or time consuming. |
