PCBN (Polycrystalline Cubic Boron Nitride)

PCBN consists of CBN and Binder. It is produced in high pressure and high temperature. It has excellent performance in hardness, wearing resistance, thermal stability.

Application: for hard ferrous materials (hardened steel, cast iron, high-temperature alloy, HSS, Powder metallurgy metals, Ni-Cr alloy...

E-Grind provides two series of PCBN:

1) Solid CBN
2) CBN with Tungsten Carbide supporting.

PCBN and SBN Grade

SBN95Z1 PCBN95Z1 20、30 0.95 Continuous cutting with large stock removal For Rough processing Grey Cast Iron, Chilled Cast Iron, Powder Sintered Alloy.
SBN90Z PCBN90Z 10、15 0.9 Continuous cutting with large stock removal For Rough process and semi-finishing processing the wear resistant cast iron, nodular cast iron etc.
SBN90Z2 PCBN90Z2 10、15 0.9 Continuous cutting with large stock removal For rough processing and semi-processing alloy cast iron, high nickel Chrome, high chrome iron and chilled steel with hardness HRC45-50.
SBN80G 3、5 0.8 Continuous cutting with Medium stock removal For rough processing and semi-processing alloy cast iron, high nickel Chrome, high chrome iron and chilled steel with hardness HRC45-50.
SBN70G PCBN70G 3、5 0.7 Continuous cutting with small stock removal For finishing the chilled steel and high temperature alloy with HRC45-55.
SBN60G 1、3 0.6 Continuous cutting with small stock removal For finishing and super-finishing the chilled steel with HRC55-62 like bearing steel, tool steel, mold steel, gauge steel and HSS.
