342 SUPER ABRASIVES
Diamond is the hardest material known to man, closely followed by Cubic
Boron Nitride (CBN). As a result of their hardness these materials are used
extensively in the most demanding precision grinding, slicing, and cutting
applications. Super Abrasive wheels use diamond and CBN technology to cut
demanding materials such as carbide, high speed steel, ceramics, and glass.
Norton provides ultimate, high performance Super Abrasive solutions for the
cutting tools industry, offering products specifically designed to deal with the
hardest and most challenging materials.
UNDERSTANDING THE PRODUCT
ASD
ABRASIVE TYPE
Both diamond &
CBN have distinctive
characteristics
that meet the most
demanding applications.
ASD: Synthetic diamond,
armoured, high quality,
versatile.
CB: Cubic boron nitride,
armoured, durable.
R
GRADE
Refers to the
degree of
durability of
the wheel,
progressing
alphabetically
from A (softest,
least durable) to
Z (hardest, most
durable).
B99
BOND
The element in
a grinding wheel
that holds the
diamond or CBN
grains together.
151
GRIT SIZE
Size of the
Super Abrasive
particles
according to
FEPA standards.
The smaller the
number, the finer
the grit size.
75
CONCENTRATION
Indicates the amount of
Super Abrasive grits in the
wheel. For CBN wheels
the concentration number
is included in the grade
(Q=50, T=75, W=100, Z=125),
concentration 100~4,4 ct/cm³,
& accordingly 50~2,2 ct/cm³.
The optimum concentration
depends upon the application.
