Diamond / CBN Grinding Tools, Electroplated Bond
CBN Grinding Points and Special Shapes
Cylindrical points with carbide shank are used
Cylindrical points with carbide shank
for internal grinding on stationary machines.
The modulus of elasticity of the carbide shank
is approx. three times higher than that of a
L
1
steel shank. The modulus of elasticity indicates
L
the amount of deformation which a body
T

undergoes as a result of a given load.

In internal grinding applications, tools with
a carbide shank offer higher stock removal
rates, superior surface qualities and longer
tool life.
Please refer to the tables on pages 7 and 8 for
the recommended cutting speeds.
