Glass Powders for Superabrasive Grain Bonding

Specialty Glass, Inc. (SGI) delivers a customer service centered approach using proprietary technology along with our flexibility to customize formulations, physical properties and particle size distribution*. We can move away from the “one-size-fits-all” approach to glass powders and work within the parameters you require. A collaborative approach to developing optimized products makes SGI a partner in your business, not just a valued supplier.

Glass for Vitrified Bonded Grinding Wheels
  • SGI can provide a custom formulation and production process in small lab testing quantities to tons.
  • Electric and gas heated furnaces to enable melting glasses up to 1600°C (composition dependent).
  • Diamond and cBN grain vitrified bonding for optimum performance and service life.

Specialty Glass Inc. builds on a reputation as an innovator in the industry with an extensive array of micron sized glass powders that meet individual requirements for vitrified bonded products. Customers can further customize “in-house” a vitrified bond mix for superabrasive grains by proportioning different sized grinds to modify porosity, bond strength and hardness.

SGI has the unique ability to fine tune glass properties tailoring to specific user applications for traditional abrasive and superabrasive grinding wheels.
