History

Why Diamond or CBN?

Diamond and CBN are used whenever carbide tools reach their performance limits. The ultrahard cutting materials offer key advantages to the material carbide:

tool life
precision
high-quality outcome

The tool lives of diamond and CBN tools are sufficient to process several 100.000 workpieces. Diamond as the hardest and cubic boron nitride (CBN) as the second hardest material can process even brittle-hard and extremely wear-resistant materials like e.g. high-alloy tool steels, ceramics, GRP, CFRP with high precision.
