CBN cutting tool – it`s changeable cutting inserts made of superhard Cubic Boron Nitride material (CBN) and applied for high speed turning (grooving) of hard-to-machine materials, such as the tungsten carbide or chromic cast iron.
We produce the solid CBN inserts.
The main competitive advantage of our tool is high concentration of CBN in material of tool (up to 97%)
Due to this reason, we got a high strength (machining with impact, turning of high-Mn steels) with high abrasion resistance (turning of tungsten carbide) of tool at the same time.
The main application of our CBN inserts is a turning of tungsten carbide metallurgical rolls. Such rolls usually applied on the production of rebar and wire.
In practice very often the Customers perform this operation at their roll-turning shops on special foreign machines ATOMAT or HERKULES using our CBN cutting tool.
You can find more information about the most popular shapes and dimensions of our CBN inserts in the following table:
