BOND TYPES VITRIFIED
Vitrified bonds are the most common precision grinding bond. Porosity and strength of the wheels made
with this bond give high stock removal along with their rigidity helping to attain high precision.
Not affected by water, acid, oils or ordinary temperature variations. The most common vitrified bonds are:
V V is the original high temperature vitrified bond, usually used where tougher acting wheels are required
VS VS is a very versatile, low temperature, high performance vitrified bond system used in almost all applications
but predominately for tool room, centreless, cylindrical, & surface grinding
VTECH Low temperature, very technical bond, used with conventional abrasives & recommended for high tech
applications to maximise performance & dressing parameters
VX VX bond provides improved corner/form holding for most applications
VXP Induced porosity VX bond suitable for large contact areas & surface grinding
VQN/VQNP These bonds are associated with Norton Quantum technology - a versatile technology for low,
medium and high force applications.
