Selection Guide Grinding Wheel Materials and Compounds
1. Abrasive Grains
Abrasive grains are particles of
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
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.
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.
