Cubic Boron Nitride Pastes is produced for semi-finishing and finishing operations. It is used for finishing and polishing operations of carbon and alloy steel, chilled iron.
Past composition is next: cubic boron nitride powder, filler with organic oils, fatty acids, carbons of paraffin series and its derivate, polymer material. Cubic Boron Nitride Paste affects on processed surface with chemical and mechanical influence. The past composition consists of surface active materials, they help with washing workpieces, and output the slags from the processing surface.
It increases productivity and the roughness of the surface.
The paste divides:
“N” – normal consistency
“H” – higher consistency
“E” – extra-high consistency
