CBN is the second hard material only after diamond.It
not only has many good features of diamond,but
also has the advantages of high thermal stability
and chemical stability to iron group.It is widely
used to process hardened steel,cold cast iron,heat
resistant alloy and other ferrous metals.
CBN30
Black, low toughness, easily
fractured monocrystal with irregular shape. Used
for resin, vitrified,electroplated bond,grinding
wheels and abrasive tools, suitable for grinding
ferrous metals and alloy in low temperature.
CBN40
Black, monocrystal with regular crystal shape and
high toughness.Mainly used for electroplated,metal
and vitrified bond,grinding wheels and abrasive
tools, suitabl for grinding ferrous metals and alloy.Optimum
balance of fracture strength and breakdown characteristics
to enhance wheel life and surface polish.
CBN50
Amber, semi toughness, irregular monocrystal
shape.Used for electroplated,metal and vitrified
bond,grinding wheels and abrasive tool,suitable
for grinding ferrous metals and alloy.
CBN60
Amber, regular crystal shape, extremely
tough, widely used in metal bond system and electroplated
tools.
CBN70
Dark brown,irregular monocrystal
with sharp-edged and high thermal
stability,used in vitreous and
metal bond systens
CBN80
Dark brown,momocrystal,highly crystallized,
extreme thermal stability,used for heavy grinding
to extend productive life in metal bond system
and electroplated tools.
