Шлифпорошок кубического нитрида бора КО, КР, КВ

КO, КР, КВ

Are made from CBN powders of the increased friability, grains are presented by assemblies and joints with the developed surface

Шлифпорошок кубического нитрида бора К8, К9

К8, К9

Are made  from CBN powders  which grains are presented by crystals, joints, assemblies with factor of the form no more than 1,2

Application КО-К9
KO - Wheels on organic and ceramic bonds for both finish and semi finish machining of high speed and difficult-to-machine steels  and alloys.
КР - Wheels  on ceramic and metal bonds for grinding of high-speed  and others quenched up to high hardness steels.
КВ - Tools for boring, turning and grinding  of quenched alloyed and bearing steel, difficult-to- machine alloys on the basis of iron and nickel.
К8 - Wheels on ceramic and metal bonds for a high-productive and honing the quenched alloyed steels and others difficult-to-machine alloy on the basis of iron and nickel, including for high volume stock removal.
К9 - wheels on ceramic and metal bonds for course and semi finish machining of quenched up to high hardness and the alloyed steels poached cast irons  and special alloys, in particular at  high productive and deep grinding, honing  including high volume stock removal.
