Has a low coefficient of friction. CBN and the friction coefficient of different materials between 0.1 to 0.3, much lower than the friction coefficient of cemented carbide (0.4 ~ 0.6), and with the friction speed and positive pressure increases slightly reduced. So the low coefficient of friction and excellent anti-adhesion ability, so that CBN cutting tool is not easy to form a retention layer or BUE, is conducive to improving the processing surface quality.
