Bosch premium grade wheels are constructed of high quality abrasive grains, bonding coats and backings for metal, concrete,
masonry, pipeline, asphalt and stainless steel cutting. Easy–to–read labels are incorporated into the manufacturing process and
therefore remain intact throughout the life of the wheel. While some manufacturers use recycled grains, Bosch uses only superior
virgin grains made to exact specifications. Carefully formulated resinoid bonds are applied to meet the unique specifications of
each wheel. Multiple layers of long, stranded fiberglass are woven to form an exceptionally strong reinforcement layer specific to
the application.
Selection Guide Grinding Wheel Materials and Compounds
1. Abrasive Grains
Abrasive grains are particles of man-made abrasive
compounds. While some manufacturers use recycled
grains, Bosch abrasives use only high quality, virgin
grains that are made to our specifications. The
chemical structure of the grains determines the
physical properties of the grains (i.e., shape,
sharpness, hardness, friability). Common grain
types used in making bonded abrasives include:
A - Aluminum Oxide - A tough, blocky
shaped grain used for cutting metals
and other high tensile strength materials
without excessive fracturing.
C - Silicon Carbide - A very hard and very
sharp abrasive suited for non-metallic
materials such as concrete.
Z - Aluminum Zirconium - A very fine,
dense crystalline grain which can be
used for rugged stock removal.
SG - Seeded Gel - A very fine, dense
crystalline grain which can be used
for rugged stock removal.
2. Bonding Agent
The bonding agent that holds the grains together determines the resistance of the
wheel. Bosch abrasives use a resinoid bond that is formulated to meet the unique
specifications of each product.
3. Reinforcement
The reinforcement material provides extra strength to use the wheel at maximum
RPMs and withstand lateral pressure that is applied during use. Bosch uses multiple
layers of long, stranded fiberglass that are woven to form an exceptionally strong
reinforcement layer specific to the application.
Combining the 3 Components
During the manufacturing process, these three components are combined to form a
grinding wheel. The grains and bonding agents are measured, combined and pressed
in an automated hydraulic press. Bosch abrasives labels are also incorporated into the
manufacturing process and therefore remain intact throughout the life of the wheel.
