Grinding with electroplated cubic boron nitride (CBN

Electroplated cubic boron nitride (CBN) wheels are manufactured with a single layer of CBN superabrasive grains held on the wheel hub by an electroplated nickel bond Unlike other conventional and superabrasive wheels these wheels are not periodically trued or dressed Consequently their performance during grinding varies significantly as the wheel wears down and its topography changes
