Шлифпорошки кубического нитрида бора КО-К9

Grinding powders from cubic boron nitride КО-К9 (standard U 88.090.018-98 KO, КР, КВ) (standard U 26.8-05417377-170:2007 К8, К9

КO, КР, КВ

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

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.
