Tool steels - Import export

CBN (cubic boron nitride) is the next hardest material after diamonds. When properly used, tools made from CBN exhibit considerably less wear than other materials. Cutting inserts or even VHM tools can be equipped with CBN. Technical application: Hardened tool steels with hardnesses greater than 55 HRC or high speed steels (HSS) can be machined without problems using CBN. Case hardened steels and chilled cast iron can also be machined with CBN. Non-ferrous metals are totally unsuitable for CBN; diamond tools are needed for these.

Contrary to external turning, tool selection and tool use are of greater significance in internal turning as these are limited by the length and hole diameter of the work-piece. During internal turning it is very important to select a boring bar which is optimal for the hole diameter in order to minimise vibrations. Zinner tools are available in steel, heavy metal or hard metal shanks.
